TIG welding requires a machine that can keep up with your skills. Finding a welder to live up to the task is as important as honing your skills.
We conducted extensive research and compared dozens of models to find the best TIG welders to keep up with every level of workmanship. From beginner-friendly welders to the most professional performance, we took the guesswork out of your next purchase. We present our list of the 10 best TIG welders on the market.
Are you a professional welder and planning to start a business? If so, the Everlast PowerPro 256Si is an excellent 250A welder that you can use for any project. It offers the best price for its features and is hands-down the best in power and versatility.
The Everlast PowerPro 256Si welder offers both high frequency and lift-start ignition, with a remarkable 40% cycle at 250 amps. It provides different adjustment options for pre-flow settings on the torch before you start working, and post-flow configuration that tells the machine what to do once you have completed your task.
The digital screen makes this welder easy to use as it shows different error codes without stopping your work. This screen is also capable of displaying color-coded messages, which improves productivity and makes it easier to focus on the task at hand.
The Everlast PowerPro 256Si offers essential features such as three-phase power levels and stick welding, which works on both aluminum and steel. It may not be ideal for beginners because it is more complicated than most welders we tested. Still, it has the best functionality and versatility of all the welders we researched and can keep up with the most demanding welding tasks.
The Lincoln Square Wave TIG 200 Welder is our best choice for hobbyists. The ease of use is unparalleled; with push-and-turn controls at the front of the machine, anyone can start welding without worrying about advanced configurations.
This welder can be used for both steel and aluminum. It has stick welding capabilities that make it versatile enough to handle the varied needs of a hobbyist. You can use it on a 120-volt outlet with a duty cycle of 25% at 125 amps for TIG and 20% at 75 amps for Stick. When used on a 230-volt outlet, the duty cycle is 25% at 200 amps for TIG and 20% at 170 amps for Stick.
The only thing we didn’t like about the Lincoln Square Wave TIG 200 is that the torch has an automatic gas shutdown, which limits the post-flow control. It is also heavier than most 200A TIG welders that we reviewed, which may not be ideal for some.
Lincoln is a very reputable brand when it comes to welding equipment and the Square Wave TIG 200 lives up to its reputation. Users who don’t have enough experience in configuring welders will find its straightforward setup to their advantage. Add it to the power and flexibility, and there is no doubt that this is the best welding machine you can buy.
The Innovator 255i is the best multi-process welding machine that we have tested. It is a four-in-one machine that includes a pulsed AC and DC welder, plasma cutter, and stick welder. There are only a handful of welding machines that can offer the same functionality, and most of these do not even come close to what this welder can do.
The Longevity Innovator 255i has built-in thermal overload protection that will safely shut down the machine when it reaches the duty cycle limit. It can also lower the temperature by concentrating the arc and evenly distribute the heat, which makes it possible for you to weld thin materials (which are highly sensitive to heat) with impeccable precision.
Another feature that we liked was the IGBT technology, which makes it possible for you to operate this machine on a generator for mobile welding tasks. Since you can switch from a 220-volt to a 110-volt outlet with ease, you will be able to weld anytime and anywhere without worrying about power supplies.
There’s no doubt that the Longevity Innovator 255i is a great machine. However, we couldn’t rank it as our best choice due to its high price and a short warranty, which only covers the welder for one year. However, if you are looking for a welder that can keep up with the versatility and portability that your work requires, this is your best choice.
The Everlast PowerTIG 210EXT is the best 200A welder that we have reviewed. It has power and flexibility unavailable on other welders in its price range. This welder is so competitive that even when compared with more expensive welders, it crushed the competition and reigned supreme.
This product is an AC and DC welder that allows you to switch from welding aluminum to steel without troublesome reconfiguration. When used on steel, it can tackle up to 7.94mm on single and 15.875mm on multipass; for aluminum, it can tackle 6.35mm on single and 12.7mm on multipass.
With a built-in high-frequency ignition and IGBT inverter, the Everlast PowerTIG 210 EXT offers better usability and portability than other 200A welders. It can switch from 110-volt to 240-volt operation, making it even more flexible. It even delivers a 60% duty cycle at 240 volts and 210 amps, which renders every welder in its class either overpriced or underpowered.
If you want a TIG welder that offers excellent value, the Everlast PowerTIG 210 EXT is a perfect choice for you. This machine is undoubtedly the best TIG welder that both professionals and hobbyists can buy. With a five-year warranty, there’s very little reason not to bring this beast home.
The Razorweld Digital TIG 200 is the best for residential use and hobbyists thanks to its digital controls. Unlike most of the welders on our list, the digital controller on this welder makes it straightforward to configure and use.
This machine operates on both 115 volts and 230 volts, and it has a duty cycle of 35% at 200A. It only works for DC welding but produced one of the best TIG and ARC welds amongst all the machines that we tested. Although the Razorweld Digital TIG 200 is not the cheapest DC welder that you can buy, it pays off well, because of its quality welds and reliable performance.
This welder offers different features that are perfect for residential use, such as high frequency, instant ARC ignition, and a pulse function that you can activate from a switch on the torch. We added the Razorweld Digital TIG 200 to our list because its features make TIG welding easy for anyone.
While this welder isn’t a good option for welding professionals, Razorweld still delivers excellent performance and top-notch support that isn’t available in other machines. It is on the pricey side but offers excellent long-term value and hassle-free welding.
The Everlast PowerTIG 255 EXT is the most robust 250A TIG welder that we tested. It produced the most consistent results, and it is more reliable than the first two products on this list. However, it has minimal flexibility, and the price is higher compared with other 250A welders on this list.
If you are starting a business, this is a welder that will give you unparalleled reliability. It is a single-phase AC & DC machine with an amperage range of 3 amps up to 310 amps. It can handle steel from 0.3 mm to 12.7 mm, and aluminum from 0.4 mm to 9.5 mm.
Everlast PowerTIG 255 EXT provides a 40% duty cycle at 250A and 60% at 200A. It also sports a memory feature that saves your most recent settings, even if you are switching between AC and DC welding. This machine also has a digital display for amps and volts, showing both the presets with the actual outputs. This gives you better accuracy and repeatability in your work.
Although it does not have a multi-function capability and is less versatile than other 250A TIG welders, this welder offers the most reliable performance that you can find in this class.
