Our top pick for the best TIG welder is the PrimeWeld TIG 225X. This TIG welder is high power, produces great welds, and is available at under $1000. Don’t let the low price put you off, this produces some quality results. These tend to sell out fast when they’re in stock, so try and get your hands on them while you can.

The 225x is the highest power welder in our reviews at 225A max output. It’s dual voltage and on 220V it can weld up to 1/4″ aluminum and 3/8″ steel. We’ve seen this on 225A on 3/8″ steel and the welds are smooth and great quality. The duty cycle is great at 40%@225A. You can also easily switch to stick mode to weld up to 1/2″ steel and is capable of 7108 and 6013. 

There’s lot of knobs on the front to fine tune your adjustments and the power output appears on a digital display. The knobs feel good to use, they’re easier to use than scrolling through digital menus, easier when wearing gloves and probably more reliable than a microprocessor. 

PrimeWeld are a relative newcomer into the market so they haven’t stood the test of time like the big name brands. That being said, most people seem to be having a lot of success with these machines. We’ve spoken to their customer service who responded pretty much straight away, and they have a 3 year warranty to protect your investment. Inside the box the equipment seems overall better than you’d expect for the price. The pedal isn’t great, it’s a bit lightweight, but it does include a CK17 Torch which is top of the range. 

Overall this machine is really hard to overlook, especially at its price. It’s perfect for a hobby welder getting into TIG and even professional welders have started using this machine.

How to use a TIG Welder?

A TIG welder requires more skill than a MIG welder because you have three things to control: the filler rod, the torch and the foot pedal. However, this allows for much more control of heat input as you can adjust these elements to achieve more specific results.

The system works by using an electric TIG torch in one hand to strike the arc with a filler rod in the other hand to feed the filler metal into the weld pool. The foot pedal controls the amperage released by the welder. You can set the maximum amperage on your TIG welder, then use the pedal to change the amperage. Holding the pedal all the way down will give you maximum amperage. This flexibility is great as it allows you to slowly start the welding process and help to prevent thermal shock in the metal.  When you set up your TIG welder you need to make sure your ground clamp is attached to the workpiece or you metal workbench.

Through the TIG torch you’ll also release Argon gas into the weld pool to protect to weld from contamination. You’ll have to hook up a gas bottle and regulator for this. Make sure you choose the right welding gas (Argon) as your MIG bottle won’t be appropriate.

Factors for Choosing a TIG Welder

Voltage

You need to decide what your primary voltage requirements are when choosing a TIG welder. The 3 options are a 120V input which is your normal household power supply, a 240V input which requires a generator, or a 120V/240V which offers both.

If you’re just welding from your home workshop, then you’ll be comfortable with a 120V TIG welder. I like to have 120/240V for maximum flexibility which allows me to get more power. Don’t buy a 240V input if you’re looking to use the welder from your household power supply.

Material Thickness

Consider the thickness of the material you’re going to be welding. This will  determine the amperage range of the welder you need to buy. A welder with a higher amperage range will be able to weld thicker metal. Remember, you can turn a powerful welder down but you can’t turn a low power welder up past its limit – so if you’re not sure about the metal thickness then go for a powerful one.

Budget & Warranty

The price of the welder is an important consideration. TIG welders aren’t cheap but you’re paying for quality results. We’ve included brands that make high-quality machines that have been proven to stand the test of time. Consider the warranty as well on welders to help protect your purchase if anything goes wrong.

Multi-process or just TIG?

When you buy a TIG welder, some will allow you to perform other welding applications such as stick welding. Depending on what equipment you’ve already got, you may consider a multi-process welder as a better option. If you’ve already got a good stick welder, then you might be better off choosing a straight up TIG welder.

Weight and portability

The weight is an important factor if you’re planning on moving the welder about. You’ll probably be best putting these machines on a welding cart as they’re not easy to transport.

Duty cycle

The duty cycle indicates the length of time you can weld continuously without overheating. A TIG welder with a 20% duty cycle at 200A could be operated for a 2 minute period at 200A and would need an 8 minute cooldown period.
