Best TIG Welder

Tungsten Inert Gas (TIG) welding (or Gas Tungsten Arc Welding (GTAW), as called by the American Welding Society) is a method of joining metals using a tungsten electrode, a non-consumable (very hard to melt). Compared to other techniques, TIG doesn’t leave melted material between the joint pieces.

This process is extremely technical and challenging to master. TIG lets you weld critical, small joints, and thin-wall tubing, so it’s is widely applicable in the aerospace and vehicle industry.

With the advancement in tech, many brands have come up with outstanding TIG welders. So, consumers with zero knowledge end up choosing the wrong product. If you’re one of them, we’re here to help you get the best TIG welder.

TIG Welding Machine Buying Guide

Users can benefit from the many advantages of TIG welders. A higher price does not equate to more top quality – at least not all the time.

Here are some factors to consider when shopping for TIG welders.

1. Amperage Range

A machine with a more extensive amperage range will cost you more, but it means you can work on many more materials.

You can choose to get something that can go higher than 200 amps if you want to work on metals such as aluminum. If you’re only using a TIG welder for small tasks, a little amperage will suffice.

2. AC/DC

Steels and stainless steels often need DC output in welding. For magnesium and aluminum welding processes, AC output is ideal – this means you need a machine with AC/DC capabilities if you’re working with a variety of materials. We advise you to get a TIG-only machine if your application is strictly TIG.

3. Heat Control

A good welding machine should offer heat control if you want good bead quality. Look for a TIG pulse in the product you want to buy – it’s a sign of good heat input control.

4. Balance Control

Welders should take a closer look at the AC balance control in their machines. AC welding inverters use high-current electronic switches for weld output.

Since the AC can vary, users can choose to concentrate the arc using high frequency.

What’s the Difference Between TIG and MIG Welding?

Metal Inert Gas welding (MIG), or Metal Active Gas welding (MAG), or Gas Metal Arc welding (GMAW), is the other common welding tech preferred by industries.

TIG and MIG welders are almost the same, except for some things:

The welding process

MIG welding process sets itself apart from TIG as it involves a continuous feeding of wire to a metal. The base metal and the weld metal get joined by the consumable welding supply of the wire (this means the wire itself acts as a “glue” – it gets used up and melted into the junction). This process creates a strong bond, which makes it more appealing to big manufacturers.

TIG, on the other hand, uses a non-consumable tungsten electrode to join two metals. A non-consumable welding material does not melt into the two joint pieces- instead, it’s merely a tool, and it works by electrodes running a current through the metals to stick them together. TIG may or may not use filler metal in the process.

Applicability to thin vs. thick metals

MIG is suitable for welding thicker objects as it uses consumable filler to join pieces together. For more substantial metal pieces, it’s not a big deal to add a little bit of filler material in-between parts.

TIG welding may not use filler materials, as mentioned above. TIG needs to weld the two separate pieces hot enough to melt and form a tacky bond of their own (really hard to do for big bulky metals). This process makes TIG better for working with thinner metals as it’s only practical to not add any more material to an extremely thin tubing or mechanical part (the most critical parts of any big machine).

If you want a two-in-one, we recommend a multi-process MIG/TIG/stick welder.

Controllability

First-timers most likely prefer MIG over TIG as the TIG torch and equipment are easy to control, and in case of mistakes, you can make changes.

Things are different for TIG welding. Perfection can only happen when a pro does the job as it requires precision, proper pressure, and timing.

The electric current used should also be appropriate for the specific metal pieces. To achieve better results in TIG, you will need an automated Computer Numerically Controlled (CNC) machine and good generators. These help you execute identical welds.

Applications of Tungsten Inert Gas Welding

Aerospace applications of TIG welding

Since TIG welding allows users to work on various metals, several industries make use of this technology to create and repair items.

The top sectors that make use of this welding include automotive, aerospace, art, and repair. So here are some of the welding jobs you can do if you’re good at TIG welding.

1. Automotive

The auto industry requires super secure and well-made construction to hold the parts of a car together. The TIG strategies can reduce corrosion, which means cars can stand the test of time – this also implies that vehicles made of TIG-welded parts are the safest.

2. Aerospace

TIG welding has a wide range of use in spacecraft and aircraft, a very critical and scientifically accurate field.

3. Art

Art is another application, because TIG welding offers a superior, more professional aesthetic, making products look the best version of themselves. Industrial fixtures and metal sculptures will always do good by this welding process.

4. General repair

Different repair applications will also be easier if you use TIG. The best part is that you can use it to fix even your child’s metallic toy! It comes in handy if you need to fix a broken pedal in your car, bike, or other broken aluminum parts. Make sure you put on safety gear such as welding helmets.

It is free from spattering – a common issue of other welding processes. You’re guaranteed neat-looking joints with superior weld quality, free of defects.

Final Verdict

With that said, you now understand the real benefits of getting top quality and highly rated TIG welders. However, making a decent purchase involves more than just checking its price. We hope our buying guide made you more informed about TIG welding and its applications.
