How Many Amps Do I REALLY Need for a MIG Welder >> 200-300 Amps?

Have you ever wondered how many amps do you need for a MIG welder? Few things are more important for welders than making sure that they have the proper amount of amperage.

Too little amperage and you might not be able to spark your welder to life, let alone have the heat and power necessary to melt and weld solid metal.

Too much and you might scorch the metal, cause the metal to bead, or overload the welder and potentially even cause it to explode.

How many amps do you really need for a MIG welder? In average you need 140 amps for 115 volts welders in order to weld up to ¼” thick steel and around 200 amps for 220 volts welders and weld up to ½” thick material.

How Many Amps Do I really Need for a MIG Welder?

You need to remember that the amperage depends on many factors like the type and thickness of the material. how many amps for a welder?

The answer to that question will change depending on what type of welder you’re using.

MIG welding is the option of choice for many welders – especially beginners – which sparks another question – “how many amps to run a welder”

Welder Amperage Chart

Are you going to be welding mild steel? Or do you anticipate working with stainless steel, aluminum, or an exotic metal or alloy?

What is the thickest thickness of the material that you expect to have to join? Knowing the answers to these questions will help you determine how much machine you need.

It’s always better to have a little bit more than you’ll need because even the kind of join that you’re welding can influence the amperage settings you’ll need to get the job done right.

Related reading: I have recently written an article in which I describe “5 Types of Welding Joints and Their Use – Complete Guide” in more detail, read this article here.

If you’re welding mild steel using stick welding techniques, the type of electrode that you’re using will influence the suggested amperage range.

E6013 is an all-purpose electrode that will weld 2mm mild steel with an amperage setting between 35 and 60.

At the same time, an E6010 or E6011 electrode will require a range of 40 to 85 amps.

To TIG weld mild steel that is 2mm thick, you will need 60 amps for a closed root butt joint, 75 amps for a fillet joint, and only 55 amps for a lap joint or an outside corner.

For MIG welding mild steel, a good rule of thumb is to adjust the welder amperage level using one amp for every thousandth of an inch of thickness.

That would mean that 75 to 80 amps would be a good setting to start out on for mild steel that is 2mm in thickness.

The welder amperage range that is appropriate will change depending on the type of material you are welding and the thickness of that material.

So, you will need to take the range of materials that you want to be able to work on into consideration when you are determining how many amps you’ll need.

Let’s take a closer look at how amperage for welders work, the specifics of amperage and MIG welding, and how you can keep your unit at the right setting.

Type of Material

First and foremost, you’re going to want to consider what type of material you are welding. Different materials have different degrees of strength, and different metals have different melting points.

Those are a lot of points of differentiation, which means that you can’t and shouldn’t use the same amount of amperage for different materials.

Among the most common metals used in welding are aluminum, stainless steel, and low carbon steel.

For welding these as well as other metals, you’ll want to make use of a melting point calculator to determine how hot you need your welder to be to melt and weld it effectively.

There is also the fact that not all varieties of a given metal are created equally, or have the same welding properties.

For example, there are three basic types of stainless steel: austenitic, ferritic, and martensitic. You’ll want to differentiate between them when determining how much heat and, thus, the welder amperage is needed to effectively melt and weld with each.

Intergranular corrosion occurs when stainless steels are exposed to high temperatures – like, say, in welding – which can in turn make them more difficult to weld.

While austenitic and ferritic stainless steels are generally very weldable, martensitic stainless steels are harder and are more liable to crack, thus, making them harder to weld with.

As a result, you may need more amperage to deal with them.

What about low carbon steel?

Well, if you’re looking for an easy-to-weld metal with a MIG welder, you’re in luck. Low carbon steel is highly weldable, requiring less effort, thus, amperage than other metals.

One reason for this is that its low carbon content makes it less ductile, which in turn makes it less brittle, thus, avoiding the cracking issues common in martensite stainless steel.

wire size

Select your wire size, according to amperage. We recommend not to change wire, therefore select your most commonly used thicknesses.

Wire Size Amps .023 inch 30-130 amps .030 inch 40-145 amps .035 inch 50-180 amps .045 inch 75-250 amps

Set Your wire feed speed.

The amperage depends on wire speed as well as the amount of weld penetration.

Too high speed can lead to burn-through. We recommend to read your manual or the weld specification sheet.

As a general rule use the multipliers in the following table chart to determine your wire speed.

i.e, for .030-inch wire, multiply by 2 inches per amp to find the wire feed speed in inches per minute (ipm).

Wire Size Multiply by using 1/8 inch (125 Amps) .023 inch 3.5 inches per amp 3.5 x 125 = 437.5 ipm .030 inch 2 inches per amp 2 x 125 = 250 ipm .035 inch 1.6 inches per amp 1.6 x 125 = 200 ipm .045 inch 1 inch per amp 1 x 125 = 125 ipm

Material Thickness

Even if you are a beginner MIG welder, it shouldn’t come as too much of a surprise that thickness plays a huge role in determining how much heat, power, and, thus, amperage you need to weld something.

That said, while thickness is always significant, the actual amperage difference can vary a great deal depending on the type of metal being welded.

In the case of aluminum, for example, a good rule of thumb in TIG welding is 1 amp per 0.001 of thickness.

That said, this rule begins to break down at more than ¼ inch in thickness.

On the whole, the thicker the piece of aluminum, the less the amperage goes up. The same basic rule holds true for MIG welding as well.

The amperage for stainless and low carbon steel tends to be a bit less intense, requiring only 2/3 of an amp for every 0.001 of thickness, which works out to an average of around 40 amps per 1 mm.

Even thickness is dependent upon other factors; however, including the direction of the heat flow.

After all, the reason more amperage is needed at greater thicknesses is that more heat flow is needed to successfully melt and weld the area.

If some of that heat flow is dissipated, some of that heat is lost, and, thus, you will need even more heat than you might have needed if the flow had been more concentrated.

Gauge Metal Thickness (mm) Metal Thickness (Inches) Required Amps 8 4,2 .164 164 10 3,4 .135 135 12 2,7 .105 105 14 1,9 .075 75 16 1,5 .060 60 18 1,2 .048 48 20 0,9 .036 36 22 0,8 .030 30 24 0,6 .024 24

A good example of this is joints. In these pieces, the heat flow is dissipated out in the different directions to which the joints extend and attach to other pieces of metal.

As a result, the heat flow and, thus, amperage necessary to weld these pieces will be greater than their straight-edged counterparts.

Last, but not least, it is worth noting the amount of voltage you’ll need to power the welder itself. 110v per every 1/4in is a good metric with which to start your welding work.

How You Plan on Using the Welder

The thickness of the material that you’re welding is one thing, but what are you welding it for in the first place? The actual welding job you’re trying to perform can have a big impact on how many amps you need to power the unit.

If you are doing a job that requires extra power, you’re naturally going to need extra amperage.

Welding gates, machinery, and other things typical of farm work typically take an amp welder with at least 200v.

However, if you are looking to do higher-octane work, or are performing tasks that require a three-phase welder, you’ll need something with somewhere between 300 and 600 amps.

On the other hand, if you are just using your MIG welder for hobbies or lower-level projects, you shouldn’t need that much amperage. A 110v machine that can produce 140 amps should be sufficient.

You’ll also want to think about where you’re using that welder. Most homes’ power sockets can support that 110v range, but above that, you’ll likely need to buy an adaptor or generator to make sure that your power source can handle the amount of amperage necessary for the job.

How Many Amps Does a Welding Machine Use?

Even if you were talking about a specific welding machine, the question of how many amps that it uses would still require a lengthy answer.

That is because almost any modern welding machine will have adjustable amperage settings that allow the user to fine-tune the machine’s function to make it more powerful when more power is required and easier to control when that is what the job calls for.

How many amps does a welding machine use? The answer depends on the machine that you are talking about. But some would argue that it isn’t even the right question to ask.

The number of amps that a welder needs to deliver depends on the kind of welding that is being done, the type of material or materials being welded, the thickness and cleanliness of the materials, and more.

It is easy to find welding machines that deliver what it takes to complete small jobs on lighter materials.

Often these machines are affordable, easy to set-up, easy to use, and easy to maintain.

But these machines tend to have limited power and typically aren’t what you’ll want if you’re doing jobs that are bigger, more technically complex, or involve challenging conditions.

How Much Amperage Should You Look for In A Welder?

Welding is one of the most useful skills that you can learn. Whether you want to make welding your primary occupation or just want to be able to make repairs to equipment around your farm or shop, there is a lot that can be accomplished with basic knowledge and skills.

Welding plays a role in everything from the arts to heavy industry. It makes sense that what works for modern sculpture isn’t the same as what works for shipbuilding or industrial ironworking.

One of the first questions you need to ask about a welding machine is whether you’ll be using it for a specialized task or whether you need it to be good for work as a generalist.

The type of work that you do will determine whether you want a MIG, TIG, or stick welder as well as how much power you need from the machine.

Higher amperage will give you more options, but it might come with tradeoffs like a higher price tag and lower portability that will make a high amp machine less desirable.

Higher amperage will give you deeper penetration that makes it possible to weld thicker materials and work faster and cleaner.

Amperage is also a key determiner of the duty cycle, which influences the amount of time that you can work before letting the machine rest.

If you’re shopping for a welding machine, you should ask how many amps you need as well as how many you’re able to run and how many your budget will permit.

By approaching your purchase this way, you’ll be able to find a machine that will do the jobs you need it to do without taking on the burden of rewiring your workspace or overspending your budget for no reason.

Questions to Ask Before You Purchase a Welding Machine

If you’re just getting into welding and haven’t settled into a preference, you will need to do some research.

There are at least three welding techniques that are common currently, and many high-end machines will give you the ability to use more than one technique. Some machines will even allow you to switch between all three.

Stick welding is probably the easiest and most basic technique to learn, but it is only easy in a limited number of circumstances, and it can be difficult to get good results on some materials or thicknesses.

MIG and TIG welding are a bit more complicated to learn, but they give welders a wider range of capabilities in terms of what they can work on and where they can work.

Whether you choose stick welding, MIG, or TIG, will help to determine how many amps you will need from your machine to be able to do the kinds of work that you want to do.

There are many jobs that you can do with any one of the three techniques, but the technique you use will help determine the amperage requirements for the job.

I have recently written an article in which I describe “the different types of welding machines and their uses” in more detail, read this article here.

How Many Amps Can You Run?

Welding machines that are powerful enough to deliver higher amperages are typically 3 phase machines that require access to three-phase power.

That isn’t an option for most homes or hobby shops. Even if a heavy-duty three-prong or four-prong outlet is available, you might still need to upgrade your circuit breakers before you can run a heavy-duty machine capable of delivering 300 to 600 amps.

Fortunately, 150 to 200 amps will be enough for the vast majority of welding tasks. That means that 115v or 220v outlets will be all that you’ll need to run your machine.

Unless you’re shopping for a machine that can run a 100% duty cycle on challenging materials, you should be able to get more than enough machine without getting into rewiring or major renovations.

How Many Amps Can You Afford?

When it comes to purchasing a welding machine, it pays to spend a little bit more to get more machine than you think you’ll need and make sure that it is a quality piece of equipment that will perform for a long time.

At the same time, it won’t do you any good to spend too much to get the biggest and best machine if you’ll never use half of the power or features that come with it.

Why Higher Amperage Matters

Having covered what factors contribute to the choice, it is worth taking a closer look at why higher amperage matters in the first place. While you don’t want to do things, higher amperes tend to be easier to work with.

There are several benefits of using higher amperages, not the least of which being that more amperage simply means more options.

The more heat and power you can generate, the greater your range of welding possibilities, which is always a good thing.

Then, there is the matter of actually penetrating the metal itself. The harder or thicker the metal is, the harder this will be, which will naturally require more effort on your part.

That said, this can get tedious and exhausting all too quickly. Besides, the amount of effort and strength you can personally give to the project is finite.

Adding extra amperage to the mix can, thus, be a great way to lessen the difficulty for yourself. After all, if there is more amperage and, thus, heat involved, the metal in question can be melted that much more quickly, thus, requiring less welding time from you.

Of course, you’ll need to make sure that you practice this in moderation. Adding too much amperage too quickly can cause burning and other severe safety issues. That said, practiced properly, more amperage means less toil.

This is especially true when welding thicker materials. As already mentioned, the thicker the metal, the more amperage it will take. Kicking that number up quicker while observing safety protocols can help you weld thicker and quicker.

Finally, there is the fact that higher amps provide greater consistency. At lower amperages, the work takes longer, which means there is more time to make mistakes.

Higher amperes expedite the process. They can also help you weld that much smoother. As a result, you can weld away all those little imperfections, producing work which is smoother, more consistent, and thus of greater quality.

By taking these factors into consideration, you can make sure that you are able to power your MIG welder with enough amperage to get the job done.

Can I Run A Welder On A 30 Amp Breaker?

Can I run a welder on a 30 Amp breaker? Yes, In the case of smaller welders with 115v, you will be able to run them on a 20 to 30 Amp breaker. For a 220v welder it is not possible to operate on low amperes and would require 30 amperes minimum but more than 30 amp is recommended.

In the end it all comes down to your usage and the intensity of the project. If you plan to use the MIG welder for smaller projects such as daily maintenance work around the house, then operation of small welder can work perfectly on a 30 Amp breaker.

However, it is important to note that a 30 Amp breaker will not trip if you hit 30 Amp limit but it will lessen the time period for it.

How Thick Can A 180 Amp MIG Weld?

How thick can a 180 Amp MIG weld? A 180 amperes MIG welder is qualify for welding up to 0.035 inch. In some cases, ½ of an inch can be welded. However, its penetration level is not as effective.

Thicker than the mentioned parameters (0.035 inch) would adversely affect the penetration level hence requiring a lot more effort.

When it comes to MIG welder amps steel thickness it’s important to understand that welders utilizing single pass are 1 ampere per 0.001 inches of thickness. This can also be understood as 250 amps per every 1/4th of an inch.

How Thick Can A 70 Amp Welder Weld?

How thick can a 70 Amp welder weld? 70 Amp welders are perfect for welding up to 1/8 inch thick sheets. This proves a 70 amp to be the best match for intricate work and small welding projects.

70 Amp welders are small and portable welders that are extremely convenient when it comes to using it for lightweight purposes.

Although 70 Amp welders are not heavy duty, it helps in performing small tasks around the house and gives you the choice for electrode attachments and earth systems.

It should be kept in mind that while 70 Amp welding machines are on the more durable and affordable end, they are extremely challenging to control and it will require time in both learning the machine and the process of welding with it.

Frequently Asked Questions

Here are a few common questions people often have about MIG welder Amps:

Can I Put A 50 Amp Plug On A 30 Amp Breaker?

The breaker capacity defines the limit of current withdrawal. For any breaker it is recommended that no more that 80% of the actual breaker capacity is used.

Can I put a 50 Amps plug on a 30 Amp breaker? No. 30 ampere breaker defines the limit at 30 amperes strictly so you should not be using more than 24 to 25 amperes when using a 30 Amp breaker.

You should not exceed the capacity of the circuit through the usage of high ampere requiring machinery. This will not only cause the circuit to malfunction but could also potentially damage your device.

Can You Plug a 15 Amp Plug Into a 20 Amp Receptacle?

The receptacle value is always supposed to be higher than the plug that is being connected to it. Most household appliances include a 15 amp plus that makes them eligible to be used in 15 or 20 amp receptacle.

Can you plug a 15 Amp plug into a 20 Amp receptacle? Yes, you can do it. A 15 amp plus has two parallel blades and a ground pin that can easily be plugged into a 20 amp receptacle.

The 20 amp receptacle provides you with a diverse range of choices when it comes the plug being used but it should always be noted that the ampere limit should not be exceeded.

A 20-amp receptacle accommodates larger influx on current and enables you to use more heavy-duty appliances. Larger power tools including welding machines can be used with a 20 amp receptacle.

How Many Amps Does A Lincoln 140 Use?

How many amps does a Lincoln 140 use? This machine proves itself to be robust and reliable through its 140 Amp tool that gets the job done on normal household power of 120 volts.

It comes in two variants called 140 HD and 140 C hat both share the same ampere usage but differ in componential qualities.

Despite them being variants, both welders all you to withdraw up to 140 amperes with no problem.

The minimum ampere requirement is 30 amperes and allows you to weld up to 5/16 inch for mild steel without gas and MIG welding up to 3/16 inch in a single pass with gas.

Lincoln 140 is one of the top tier welding machines available on the market.

Conclusion

When it comes to welding, there aren’t many simple answers. That’s because so much of what you need to know to find the right answer depends on variables like the type of work you’re doing and the type of materials you’re welding.

If you know that you have enough welding work to do that you are considering investing in a machine, you should know the specific answers to those questions that will allow you to determine how much machine is enough and how much is too much.

A beginner’s guide to buying a welder for light fabrication, maintenance, motorsports, home-hobby, farm/ranch, metal art, automotive and other DIY applications

Understanding your Needs

While all ESAB welders let you accomplish many welding projects, there is one series of welders that gives users more flexibility than any other welder on the market: the Rebel Family. This portable, integrated multi-process welding system lets you weld using the MIG, flux cored, Stick welding and TIG welding processes.

No other compact, lightweight welder offers more flexibility than the Rebel! Review the chart below for a quick snapshot of all the possibilities with its multi-process output.

When buying a welder, consider the following factors:

Primary power requirements

Portability, size and weight

Welding output and duty cycle

Electrode selection

Shielding gas requirements

Input Power Requirements

Before buying a welder, you need to determine if the primary power you have available (or can have an electrician install) is compatible with the unit. Consult the operating manual or spec sheet and look at requirements for primary voltage (range, phase, frequency), minimum primary circuit size and recommended circuit size (required to achieve maximum output).

For example, the Fabricator 181i has the following requirements:

Primary voltage: 208 – 265V AC, single-phase, 50/60 Hz

Minimum circuit size: 208 – 230V/25A

Recommend circuit size: 208 – 230V/40A (or 230V/50A)

As a general rule, consider the following:

A welder running on 115V primary requires a minimum breaker size of 20A with 30A recommend (this would be for welding at up to 140 amps).

A welder running on 208 – 230V primary requires a minimum breaker size of 30A with 50A recommend (this would be for welding at up to 180 amps).

Welding at an output of 200 amps or more requires at least a 50A breaker.

Note that some power sources accept different types of primary power. For example, the Thermal Arc 161 and 201 Stick welding and TIG welding inverters accept both 115V and 208 – 230V primary power, as does the Thermal Dynamics Cutmaster 42 plasma cutter.

Portability, Size and Weight

In the days before inverter technology, getting the welder to the work site used to be a challenge in many situations. Small MIG welders weigh 70 lbs. or more, Stick welders typically weigh more than 100 lbs. and TIG welders are even heavier. Even moving one of these welders around a shop without a wheeled cart could lead to lower back strain.

Welding Output and Duty Cycle

The output or “size” of a welder is measured using amps, volts and rated duty cycle. Duty cycle is the amount of time a welder may be operated at a given output without exceeding the temperature limits of its component parts.

Duty cycle is always measured using a 10-minute cycle. For example, the Fabricator 181i has duty cycle of 20% when MIG welding at 180 amps/23 volts. This means the unit can weld continuously for two minutes at this output. It will then need to cool for the remaining eight minutes.

Duty cycle and welding output are inversely proportional. When welding at lower outputs, duty cycle increases. For example, the Fabricator 181i has a duty cycle of 60% when MIG welding at 113 amps/19.7 volts.

Note that duty cycle is evaluated at a specific ambient temperature. Thermal Arc uses 104o F. Some other industry leaders use this standard, while others use a lower temperature (e.g., 86o F); these other units will need to be “de-rated” when welding in hotter conditions.

Amperage and Metal Thickness

When someone asks, “What thickness of metal can that unit weld,” they are really referring to metal thickness that can be welded in a single pass while achieving full penetration.

When buying a welder, consider the following as general rules:

A 140-amp unit can weld up to about 1/4” steel

A 180-amp unit can weld between 3/8” and 5/16” steel

A 200-amp unit can weld between 5/16” steel

A 250-amp unit can weld 1/2” steel

Broadly speaking, you need 1 amp of power for every .001” of steel thickness. Stainless steel and welding out-of-position require 10 to 15% less heat input, while aluminum requires about 25% more. Here are some common metal thicknesses in gauges/fractions, decimals and metric equivalents.

Gauge or Fraction 24 22 20 18 16 1/16 14 1/8 10 3/16 1/4 5/16 Decimal (in.) .0239 .0299 .0359 .0478 .0598 .0625 .0747 .125 .1345 .1875 .250 .3125 Metric (mm) .607 .759 .912 1.214 1.519 1.588 1.897 3.1750 3.416 4.763 6.350 7.938

When discussing amperage and metal thickness, be sure to consider these points:

1. Welding thicker metal can be accomplished by beveling the edges to create a V-groove and then making multiple pass welds (often called “running stringer beads”). The heaviest construction equipment and thickest pipe is often welded with a 1/8” diameter Stick electrode run between 110 and 165 amps.

2. An old trick for increasing penetration on thicker metal is to heat it with a torch until it reaches about 250o F (which you may want to do anyway to drive off moisture).

3. In many applications, using a smaller diameter electrode increases control over travel speed, the weld puddle, weld bead placement and heat input. When welding on thinner metal (auto body work is a good example), good arc characteristics at low outputs (e.g., good arc stability, positive arc starts, low spatter) are far more important than total power.

4. Consider the nature of the projects you plan to tackle. Long, continuous wire welds on thicker metal with larger diameter electrodes will call for a welder with a higher output and duty cycle. Conversely, a Stick welding electrode burns in about 1 minute, after which you need to stop and chip slag. During that time, the welder will cool.

5. The current carrying capacity of the electrode selected dictates maximum welding output. Here are a few common electrodes and typical operating ranges.

Shielding Gas Selection

Different processes and base metals require different shielding gases:

For short circuit MIG welding, use “C25” or “75/25” (75% argon blended with 25% CO2). C25 produces less spatter and less heat than welding with 100% CO2.

You can use 100% CO2 for more penetration on thicker material, but be aware that it creates more spatter.

For MIG welding aluminum, use 100% argon.

For MIG welding stainless steel, use a “tri-mix” blend of approximately 90% helium, 7.5% argon and 2.5% CO2.

Spray transfer MIG welding requires a different gas blend, generally a 90% argon/10% CO2 mix. Basically, the spray transfer process requires a MIG welder in the 200+ amp category.

100% argon is acceptable for all TIG welding applications.

Consult with your welding supply distributor if you have any questions about shielded gas choices.

Notes on Selecting a Stick Welder

Stick inverters make it much easier to learn to weld because they have a “hot start” function. During Stick arc initiation, the rod is prone to sticking because the voltage drops to zero when the rod touches the work piece. Hot start helps to free the rod and establish the arc by automatically boosting the welding current for a fraction of a second during arc starts. Once the arc is established, the hot start function shuts off.

Stick inverters also have the ability to adjust arc force or “dig” characteristics. Increasing dig creates a stiffer, more driving arc that helps prevent the rod from sticking when welding overhead or welding in tight fit-up situations. 7018 electrodes especially tend to run better with a little more arc force added, while 6011 and 6013 electrodes favor less or neutral arc force settings.

Note that some conventional Stick welders are built specifically to excel at welding with one type of electrode or in one particular application (it has to do with their volt/amp curve, which is an advanced topic). Because Stick inverters with arc force adjustment enable you to adjust the arc characteristics from soft to stiff, you always get the best performance in any situation.

People who grew up welding with a classic Stick buzz box and its AC output might be concerned about switching to a DC output. However, if you imagine an electric current flowing only in one direction, it’s easy to picture how a DC output creates more positive arc starts, helps keep the arc established and makes the rod less prone to sticking. These benefits make Stick welding a lot easier to learn! Other benefits of a DC output include reduced spatter, easier out-of-position welding and better weld bead aesthetics.

Notes on Buying a MIG/Flux Cored Welder

Inverted-based MIG welders create extremely positive arc starts (little or no popping) and a very stable welding arc with minimal spatter. They can react to changing welding conditions (typically arc length and electrode stick out) extremely quickly and adjust their output to maintain consistent performance.

Inverted technology also makes it affordable to incorporate features found on industrial MIG welders, such as inductance control. Without going into too much technical detail, adding inductance decreases the number of short circuits per second while increasing the amount of arc-on time per short circuit. This creates a more fluid weld puddle (better “wet out”), which in turn produces smoother beads and a flatter crown.

Inductance noticeably improves results on stainless steel. The properties of stainless keep the heat of the welding arc very localized. The puddle does not like to wet out, resulting in a ropey looking bead with a high crown. Adding inductance—more arc on time—helps solve these problems.

Some features to look for that aren’t related to inverter technology:

Burn back control, which improves arc starts by regulating how much wire “stick out” remains after you let go of the MIG gun trigger. If your application requires a large number of arc starts or very positive arc starts, such as for spot welding or on thin metal, you’ll really appreciate burn back control.

Spool gun compatibility. Spool guns are considered essential for MIG aluminum, are an easy way to quickly switch to a second type of wire and are a good way to prevent stainless steel wires from becoming contaminated by the steel wire shavings in your regular MIG gun liner.

A quick note about MIG aluminum: If you plan to weld aluminum in critical applications or on a commercial basis, consider a power source with sufficient output for spray transfer or pulsed spray transfer welding. These processes ensure better fusion when welding aluminum.

Notes on Selecting a TIG Welder

Choose the TIG weldingprocess when you want the best weld bead appearance possible—that classic “stack of dimes” look—or need more precision and control, such as for chrome-moly tubing in motorsports applications.

As with MIG and Stick, TIG inverters provide positive arc starts and a smooth, steady welding arc. Industrial-grade TIG inverters may also have pulsing controls, which help increase travel speed and reduce warping in thin stainless steel applications.

Here are other considerations when selecting a TIG welder:

Metal thickness for 180 amp mig

Metal thickness for 180 amp mig I have a buddy who has been using a 120v mig and has decided to move up. He is looking at a Lincoln K8421-1, 180 amp, at Lowe’s but says it shows on the box that it will only weld 3/16″ steel in a single pass using gas. Says it will do ½” with fluxcore in a single pass. He claims his old mig would weld 3/16″ in a single pass. I don’t know if he’s right or not, but does that sound right? A 180 amp mig will only do 3/16″, not up to ½” in a single pass. He just doesn’t want to use fluxcore wire.

All I have is a stick welder so don’t know much about migs at all. I recommended he go with a Miller or Hobart since that’s what most people on these boards seem to use. Any help fellas?
