TIG welding is technically referred to as Gas Tungsten Arc Welding (GTAW). Instead of a wire being fed by a wire feed, or a stick electrode being struck against the metal, TIG welding uses a torch to heat the metal to its melting point at which time a filler metal is added to it forming the weld bead. The TIG torch uses a sharpened tungsten electrode to form a very precise electric arc surrounded by plasma that melts the base metals. The filler rod is simply dabbed into the weld puddle and as the torch moves along the weld joint more filler is added to make a weld bead.

Best TIG Welder

It is important to note right off the bat that TIG welding takes practice and finesse to get right and for the amateur welder there may be a steep learning curve. TIG welding also requires the use of an inert gas to shield the weld area and help the arc generate the plasma necessary to heat the base metals to the melting point.

One notable advantage to purchasing a TIG welder is that they double as a stick welder too. So anytime you need to weld something a little heavier or outdoors then you can switch over to stick and weld away.

In this article we will run down our top picks for TIG welders available online and list the specifications and the pro’s of each along with our opinion on the utility of each welding machine. To finish the article off we will provide a buyers guide to aid you in your decision.

AMICO POWER ATIG1852018 TIG-185/180 Amp HF TIG

Now we are getting into more of the budget models of this list. This Amico welding machine is a dual voltage 180 amp TIG machine that includes almost everything you would need to get started. This machine does not include a gas regulator/flow meter and even though it is listed as being high frequency, it is high frequency start only so this machine will not weld aluminum. It also doesn’t come with a foot pedal current control so it will be a bit tricky for the amateur welder to get used to.


For the homeowner who only TIG or stick welds occasionally and has no need for aluminum welding machines like this one are a fine choice. The lack of a gas regulator/flow meter is unfortunate as is the lack of a foot pedal for amperage control.

Buyers Guide

Safety First

All arc welding uses an electric arc which emits ultra-violet radiation that will burn your skin and eyes if not protected. All forms of arc welding require the use of a welding helmet with the appropriate shade of filter lens and even though TIG welding has no sparks the body must be protected just the same. No skin should be exposed and the clothing worn must be non-flammable and thick, such as cotton, wool or leather. The fumes and smoke given off can be toxic so wear a respirator as well and only weld in well ventilated areas.

One hazard unique to TIG welding is the use of Argon as the shielding gas. Argon is heavier than air and if inhaled into the lungs is very difficult to expel. Care must be taken when welding overhead to not allow the flow of Argon gas to fall in such a way as to inhale it. Also be aware of welding in confined areas as the shielding gas will displace the oxygen in the space leading to asphyxiation.

It is imperative that no matter what you take safety very seriously because the damage to your eyes from arc flash is extremely painful and can cause permanent damage. The use of electricity as the basis for electric arc welding also means that you must take the risk of electrocution seriously as well.

Things You Will Need

TIG welding requires the use of an inert shielding gas which is most commonly Argon. These gasses come in high pressure cylinders and can be bought at your local welding supply shop. Tungsten electrodes are also required which is what conducts the electricity to form the arc. Steel and aluminum require different compositions of tungsten electrodes and require different shaping of the ends to weld correctly.

A bench grinder is used to shape the end of the electrode to a sharp point for welding steel and stainless steel.

Aluminum usually is welded using a pure tungsten electrode that has the end formed into a ball. The method for doing this is easy but outside the scope of this list information on how to do this can be found online or from your local welding supply shop.

Steel and stainless steel usually use a Thoriated electrode that is sharpened to a point which helps guide the arc to become very directed and precise. Other types of tungsten electrodes can also be used for welding the steels but 2% Thoriated is the most popular.

Aside from these in order to weld you need to have filler metals that are appropriate to the base metals that you intend to weld which the local welding shop can help you choose.

Which to Choose?

With so many options it can be hard to pick the right welder for your needs. The main considerations should be the input voltage, types of metal, portability and the ease of use. Aside from these the one last consideration as always for machines like these is your own knowledge of the art of TIG welding.

Input Voltage

For the most part any dual voltage machine will do just fine for the average homeowner or hobbyist but there are occasions where someone may have a shop or a garage set up with 208 or 230 volt service and never intends to move the machine. In these cases a TIG welder that is strictly 230 volts would be preferable. It is important to keep in mind that the output amperage will be significantly less with 110/115V power so keep that in mind. Also be aware of the amperage of the circuit breaker that will be used and the input amperage of the machine you use. Installing a 20 or 30 amp breaker over the standard 15 amp breakers will prevent you from having to constantly reset a blown breaker every time you push the amperage of the welding machine. Always consult local codes and an electrician before changing out circuit breakers especially for a welding machine.

Type of Metal

If you want to weld aluminum you need to have a machine that is capable of welding AC high frequency and you must have foot or hand amperage control. Foot controls are often easier to operate as they are just like a gas pedal. If welding steel or stainless steel only, than a DC machine is more than sufficient. High frequency start is a great option to look out for because it reduces contamination on the base metal from using scratch start to start the arc. For a lot of applications in welding steel and stainless steels a machine with lift arc or scratch start is sufficient especially for those who do not require high quality welds.


One of the nice things about these welders is the portability factor that comes with their small size add in the dual voltage and you can have a stick/TIG welder damn near everywhere you can think of the use of 115V power though reduces your ability to weld thicker materials so keep that in mind.

Ease of Use

Some of the higher end welders come with automatic features that make their machines easier to use but by far the best tool that will aid in making TIG welding easier for you is a foot pedal amperage control. Once you get the hang of it, controlling the heat of the arc becomes almost intuitive. Aside from what the machine does for us, TIG welding comes down to fine motor control and practice which all the advanced features in the world can not help with.


As with any tool, a welding machine is only as good as the person operating it. If you’ve never welded before it would be beneficial to take a class or two at your local technical college or welding supply store. TIG welding is not a difficult process but there is a lot of technical aspects when it comes to the tungsten, gas, or filler rod selection that should be understood before diving headfirst into this welding process. Any welding supply shop can and will point you in the right direction and answer any questions that you may have.
