Best TIG Welder Reviews


Best 250+A TIG Welder

If you’re a professional, you need the best TIG welder on the market. This means, opting for as much power as possible. To get the best TIG welder with 250 amps, you’re going to need to make a sizeable investment. With that said, you’ll have a machine that can handle just about anything.

Here are our top two choices as the best 250A or better TIG welder.

1. Everlast PT325EXT

Everlast PT325EXT

Rugged Infineon IGBT Module Inverter Digital Infineon Microprocessor Industrial 60% Duty Cycle at 250 Amps AC/DC TIG/ DC Stick functions

Of course, we give our first place spot to the Everlast PT325EXT. It provides plenty of power plus tons of versatility. To maximize your power, you’ll want a TIG cooler to use in conjunction with this machine.

When welding aluminum, you’ll find this welder provides a smooth, stable arc which starts off easily. It also works with single to three-phase power.

Surprisingly, it offers a 40% duty cycle at 320A, 60% at 250A and 100% at 200A. It also comes with plenty of adjustments so you can ensure a job well done. There’s no denying this was built with industrial performance in mind.

It packs more punch than any other welder in the Everlast line, but the price reflects that. The most useful feature is the Advanced Pulse. This increases the welding penetration while working with aluminum. It also comes with waveform control and AC balance control.

Something else that Everlast has going for them is the exceptional warranty period. You get five years parts and labor with this unit. At 60 pounds, it is on the heavy side, but certainly not impossible to tote around if you need to.

Overall, it’s a top choice when it comes to professional TIG welder options.

4. PrimeWeld CT520D

PrimeWeld Ct520d

Combines plasma cutting, TIG/stick and arc welding functions in 1

As a great choice for the best TIG welder, you might be interested in this combination machine. It features a 200A stick and TIG welder plus a 50A plasma cutter. That gives this unit more value for the money and creates versatility.

Other than the exceptional power it offers, it’s also remarkably efficient. At max amperage, you can expect a 60% duty cycle, which is impressive. Just keep in mind that it’s only a DC welder. Even still, it works well for steel; we just don’t recommend it’s usage much on thinner material.

All the parts are made in the United States and the company offers seven day a week customer support. This is helpful if you find yourself with a question. Should something go wrong, which we don’t foresee, they even offer a three-year warranty.

Finally, the portability is one of the major selling points to this unit. Weighing just 32 pounds, you can take this machine almost anywhere with you. It’s portable, reliable and well-priced; an all-around great device.

Check out this project that was done with the PrimeWeld:

What Customers Say

Customers rave about the customer service with this company. Aside from that, the welder itself is valuable and worth far more than what’s being charged. Here’s what one person had to say, “The prime weld ct520d is the best machine that I’ve worked with for small projects such as log splitters cut up to 1-inch steel with no problem recommend buying extra chips ahead pack of 26 p l 60 plasma cutter torch tips.

Best Under 200A TIG Welder

If you want the best TIG welder, but you don’t want to invest too much money, you might do better with a lower amperage model. Typically, these work well on thinner materials such as aluminum, so you won’t find the same versatility. If you don’t work with heavier metals, then these are sufficient. They are geared mainly toward the home user and not for professional usage.

1. Hobart 500551 EZ-TIG

Hobart 500551

Easy-to-Use Interface; All you need to do is power it up, select your material, and set the material thickness range

This entry level welder from Hobart is impressive and the price isn’t too high either.  It features both AC and DC functionality plus it operates at 230V. The controls can’t be any simpler. There’s just one dial that you adjust for your amperage. Choose from 10 and 165 amps plus use the single switch to go back and forth between the AC and DC operation.

The included foot pedal offers easy control while welding. There’s also a high frequency start to allow non-contact arc start. Some of the features further extend this machine’s longevity, which makes it a great value.

The fan on this welder reduces the potential debris which gets pulled in during cooling. In addition, there’s an automatic high-temperature shutdown which further protects you. The duty cycle isn’t overly impressive, but we didn’t expect it to be on this beginner unit. At 150A it has a duty cycle of 20%, but that jumps to 100% at 50A. If you compare it to an entry-level Miller machine, you see this one lacks.

Still, it’s a solid welder and quite durable. It works with 22-gauge to 3/16” materials; either aluminum or steel. Of course, it also comes with Hobart’s long five-year warranty which is another plus.

On the downside, it does weigh 50 pounds. While this doesn’t seem overly heavy, it is for an entry-level machine. With that said, when you are just learning, flexibility is more important than portability.

What Customers Say

Some people use this to learn on, while other customers found it made a great second welder to take with them. Here’s what one person had to say about the operation, “Have used this welder for about six months now and its working terrific. The quality is terrific and Hobart support is the best. Have used on a variety of aircraft 4130 steel and on aluminum and have no complaints.”


  • Amp capacity: 165A
  • Voltage: 230V
  • Weight: 50 lbs
  • Dimensions: 26.8 x 13.7 x 20.8 inches
  • Warranty: 5-year limited
  • Great for beginners
  • Easy to operate
  • Exceptional warranty
  • High-quality
  • Plenty of features included

  • Heavier than most entry-level machines
  • Not as powerful as some others


2. Forney 322 140-Amp MIG/Stick/TIG

Forney 322 140-Amp

Processes include MIG (Gas), Flux Cored (No Gas), Stick and TIG

Of all the TIG welders in this category, the Forney 322 shines above the rest. It has one of the best prices, capability and quality in this power range. This multi-process machine handles TIG (with separate parts), Stick plus MIG welding. That’s why it’s a great all-around machine for any home welder.

To use the 322 for your TIG welding, you will need to purchase a foot pedal and TIG torch separately. This adds some additional cost to your upfront expenses. Even still, you’re getting a great deal when compared to many of the other units.

Just keep in mind that the 322 isn’t geared toward heavy fabrication work. As a MIG welder, it handles ¼” of material, but it requires a decent amount of preparation to ensure the weld is strong. You have to make sure there’s no grease or dirt on any of your material and then hit it with a grinder or wire brush first. In addition, you’ll want to ensure a stable ground connection.

Anything you weld below ¼” should be a piece of cake. That’s why this is the best TIG welder for smaller, household projects. It’s also easy to use and simple to control. Just select what type of welding you wish to do, make your adjustments and get started.

Not only does this unit come with a five-year warranty, but it only weighs 38 pounds. That’s lighter than most of the machines we’ve reviewed for you. It also features a duty cycle of 60% at 60A and won’t require a special outlet to run.

Check out the video that Forney uploaded about this welder:

What Customers Say

You’ll have trouble finding anything negative to say about this welder. In fact, here’s what one customer thought, “This has been a great welder for the money. My son and I are using it to restore a ’75 Jeep CJ5. It was easy to figure out and has been a solid performer.”


  • Amp capacity: 140A
  • Voltage: 120V
  • Weight: 38 lbs
  • Dimensions: 20.2 x 10.2 x 16 inches
  • Warranty: 5-year limited
  • Great for beginners
  • Easy to operate
  • Five-year warranty
  • Durable
  • Multi-purpose

  • Need to purchase extra equipment for TIG welding
  • Not designed for professional welding


3. Forney 324 190-Amp MIG/Stick/TIG

Forney 324 190-Amp

Acceptable Electrode Diameters are up to 1/8

As a slight upgrade from the last model, we have the 190-amp Forney. It still features a good price; just with a little extra power. It’s built of high-quality materials for a long life and doesn’t cave under pressure. This allows you to work on your boats, automotive projects, farm equipment and more.

We love that it can be used for MIG or TIG welding because it eliminates the need for purchasing two machines. It also operates on both 120V and 220V for complete customization. Both welding guns are included as is the adaptor you need.

At just over 50 pounds, the machine isn’t too bulky either. You could carry it around with you if you desired. With that said, there are a couple of points about this machine that don’t please us. First, the wire feed speed knob doesn’t seem to be made of the same quality as the machine. It feels flimsy and uncertain. You also aren’t going to be able to weld any thick materials, but that’s too be expected with this lower-priced model.

Still, Forney stands by all their products with a five-year warranty. We’ve also heard great things about their customer support. Overall, you can’t go wrong with this purchase if you need to work around your home.

What Customers Say

Customers can’t stop raving about the support from Forney. Read what this user had to say, “Once I received the new one, I set it up and called Zach. Not only did he walk me through the proper use of the machine, he spent at least a half hour reviewing general welding practices with me.”


  • Amp capacity: 190A

Best TIG Welder: Buying Guide

More of the TIG welders on the market are being shipped from overseas. While that doesn’t mean they are all junk, a good portion of them don’t live up to our standards of quality workmanship. That’s why you want to evaluate each TIG welder by these criteria to determine what’s best for you.


The most important part of the best TIG welder is the amperage range. The larger the range, the more versatile it is. For example, a TIG welder with a 5-230 A output range allows you to weld anything.

The best TIG welder also features a good performance even when at a lower amperage. That’s what makes it flexible and offers you the most control over the arc.

Low amperages cause the arc to get bouncy at times. This tempts you to increase your amperage to steady it. If you plan to work with thin metal, the higher amperages might burn through it. That’s why you need as much flexibility with the range as possible.

AC & DC Capability

For maximum flexibility, you want a machine that has both the AC and DC output. For harder materials such as stainless steel, you want DC. On the other hand, AC capability is best for self-oxidizing metals such as aluminum or magnesium.

The AC gives the welder the opportunity to clean away oxidization at the same time the weld is performed. You’ll also want a balance control for the AC to shorten or lengthen the welding and cleaning cycles.

Some of the best TIG welders come with automatic balance control. This adjusts alongside the output amperage. If you have room in your budget to purchase the best TIG welder with automatic balance control, we highly recommend it. These improve the appearance and quality of your weld overall.

Heat Control

It’s critical that you control the heat on your TIG welder. When you work with thin and delicate materials, you’ll warp the metal when you apply too much heat.

Some welders choose to use pulse welding as a way to minimize the warpage. This alternates between the low and high peak current during operation. Pulse welding also stabilizes the arc while creating a reduction in heat on the material.

Again, if you have room in your budget, this is an excellent feature to invest in.

Solid Duty Cycle

The duty cycle is the measurement given to tell users how long your machine runs at a given output within ten minutes. For example, if you have a 200A welder featuring a 40% duty cycle, that means your device runs four minutes at 200A before you need to let it cool.

The lower priced TIG welders have duty cycles around 20% or less. They also come with smaller power supplies. The best TIG welder comes with a heavy-duty cycle near 60%, but it’s going to cost you a good chunk of change.

The larger the power supply, the more power it has. That increases the price substantially with every bit of power it receives. If you can afford to buy the best TIG welder with plenty of power, then do that. Otherwise, you might be disappointed with the results.

Simple Operation

We’ve already established that TIG welding requires skill. That doesn’t mean you should have a difficult time figuring out the machine. You want the best TIG welder to be user-friendly and easy to understand.

The controls should be laid out in a manner that you understand. Having accessories included that make the task easier are also helpful. For example, a foot pedal gives you control over the amperage and allows you to focus on your job.

We don’t recommend skimping on a foot pedal. It’s like driving a car without an accelerator. If the unit you plan to purchase doesn’t come with one, make the investment to add it on.

Biggest Mistakes When Buying the Best TIG Welder

Avoid some of these common mistakes when you purchase the best TIG welder.

  1. Check the input voltage – Make sure you understand what type of power you need. Some of the welders operate on both 110 and 220v, while others only use one.
  2. Understand the functions – If you don’t plan on using some of the functions, then you’re spending money for nothing. Evaluate all the features and make sure you’ll use them.
  3. Determine if you need a cooling unit – Larger TIG welders require separate equipment for cooling if you want to achieve maximum power. This is going to add more money to your cost, so you want to know this upfront.
  4. Understand the power demands – If you might need more power in the near future, consider this before making a purchase. It’s best to spend more now and have the machine you’ll need than to turn around in a few years and make another purchase.
  5. Don’t overbuy – Of course, you want to think ahead, but don’t buy more than you’ll need. If you’re just a hobbyist, then pick a unit that has enough power and a low duty cycle to save some money.

TIG Welding Tips for Beginners

TIG welding is dangerous because of the exposure to gases and heat arcs. That’s why you need to ensure you follow all the safety protocols necessary before you begin welding.

Here are some of our best safety tips for TIG welding.

  1. Wear safety gear. Consider the benefits of using gloves, helmets, goggles, jackets, long sleeves, aprons, close-toed shoes and pants.
  2. Always work in a ventilated area. The fresh air reduces the toxic fumes in your area.
  3. Ground all your welding equipment properly. If not, you face an electric shock risk.
  4. Maintain a dry work area. Any moisture increases the chance of electric shock.
  5. Prior to welding, clean off the impurities on the surface. Contaminants and pollutants affect the weld quality.
  6. Don’t weld with the wrong current. The electrode and metal you use determine what current you need. It’s wise to cut off some scrap metal and test the settings there first.



If you need the best TIG welder, you’ll want to first evaluate your needs. Then, take a look through our top ten best TIG welder reviews to find the machine that fits your tasks. You can find budget-friendly options as well as some top of the line professional units. Once you’ve invested in your new machine, it’s time to get to work.
