How to Choose Which TIG Welder To Buy?

Buying a new TIG welder doesn't take as much time or research as you might expect. With our helpful TIG welder buying guide, you can see the most important features before you start shopping.

Price

Setting a budget before you shop can help you decide how much you want to spend on a TIG welder. Don't ignore the products that are a little more expensive though. You might find that you can get a better welder for just $20 or $50 more.

Affordable TIG welders cost less than $200 and include the Amico TIG 225. SUNGOLDPOWER also makes a nice welder for less than $250. You can easily find some solid TIG welders for around $300 or less.

Pulse Rate

For pulsed welding, you'll want to look at the pulse rate of the machine. While older machines produce around 4,000 to 4,500 pulses per second, newer welders can produce up to 5,000 pulses every second.

Pulsed welding is helpful when working with thin pieces of metal that might break with standard welding. It reduces the heat that touches the metal to keep it from breaking. TIG welders with a higher pulse rating give you more control and produce a stronger weld.

Foot Pedal

With TIG welders, you'll often want to look for one with an included foot pedal because you need both hands to control the weld. You keep one hand on the torch and the other on the filler rod. With the foot pedal, you can control the welder when you cannot touch it.

The best foot pedals have a natural angle to the ground that won't cause any pain or discomfort in your foot. You should also look for one that is responsive and will respond instantly when you adjust your foot.

Air-Cooled or Water-Cooled

TIG welders also come with features called either water-cooled or air-cooled, which explains how the welder cools itself as it reaches a high temperature. Air-cooled models use the temperature of the surrounding air and can run hot. This will keep you from working in tight spots because the heat penetrates your work gear.

With a water-cooled TIG welder, you can more easily handle the extreme temperatures. These TIG machines come with a tiny head that can get into small spaces. Some who buy air-cooled welders later wish that they invested in water-cooled models.

Amperage Range

Another feature to consider is the amperage range of the TIG welder. You generally want a wide range that can help you in different situations and applications. A smaller range can limit where you can use the TIG welder and make it impossible to use in on some welding jobs.

A good range is usually between five amps and more than 200 amps. This lets you weld aluminum pieces of up to 1/4-inch thick and handle stainless steel of 20 gauges or more. With the best TIG welder, you may not need any other machines for your work.
