Best TIG Welder

The Best TIG Welder 2019

TIG is an acronym for Tungsten Insert Gas and by using a TIG welder, you are able to produce stable arcs. The process of TIG welder involves holding a torch with one hand and feed the filler rod with the other.

The best TIG welder is the AHP AplhaTIG 200X, which can produce thin and precise welds as well as having dual input power phases.

Unlike a MIG welder that uses a continuous feed of wire, a TIG welder uses long welding rods for producing stable arcs. It can also be used for welding a range of metals such as aluminum, steel, copper, brass and much more.

TIG Welder Buying Guide

Tungsten insert gas or TIG for short is slightly difficult to learn to begin with but is very versatile once you have mastered your technique. Unlike other welding devices, it is able to join a wide variety of materials with a clean precise finish.

TIG welders are fairly expensive when compared to MIG, flux core and stick alternatives but are very desirable for professionals and enthusiasts. Many can even double up as a stick welder.

To help you make an informed buying decision, we have produced the below guide regarding TIG welders.

Why Choose a TIG Welder?

Unlike a MIG alternative, a TIG welder will weld at a slower rate in order to have greater precision. This is a major requirement for welds that need to be aesthetically pleasing such as expensive machinery and makes a TIG the best option.

They are also more easily applied to thinner materials that require superior weld produce with or without filler metal. The TIG welder will produce lower distortion without the addition of any splatter too.

In terms of the weldable materials, it can weld aluminum, mild steel, copper, brass, titanium and other metals at a range of thicknesses.

AC, DC or Both

TIG welders are available as an AC, DC or one that can switch between the two. Direct current for welding provide faster deposition rates, which results in a deeper penetration. This makes it ideal for stainless steel and other hard facing metals.

An alternate current for welding has a reversed direction of the current and magnetic field of the arc. This makes it ideal for magnetic materials and it is the best option for welding aluminum. However, the quality of the weld may not be as neat as the DC alternative.

Due to the advancements in technology, you now have the option of a AC/DC TIG welder. This will allow you to switch between AC or DC to suit your welding requirements and is highly recommended.

Amperage Range

To ensure that the TIG welder you choose is suitable for a range of application, you will want the widest possible amperage range. All the recommended TIG welders above offer great flexibility and start from as little as 5A to as high at 260A.

If you plan to use a TIG welder for aluminum, you will require a high amperage unit. Trying to save money with a cheaper alternative may reduce the thickness of the material you are able to weld.

Duty Cycle

The duty cycle of a TIG welder refers to the amount of time it can run before requiring a cooling down period. Most manufacturers specify the duty cycle as a percentage of the total active time, which is usually 10 minutes.

Depending upon how powerful the welder makes a big difference to the duty cycle. Most premium examples that perform the to highest of standards can operate for over 6 continuous minutes (60% duty cycle) before needed to cool down.

Arc Starting

Whether you weld via a DC or AC input, a current must flow from the tungsten to the welding material. Starts can become an issue as to begin welding, it must defeat the resistance of the tungsten.

One method of achieving this is by scratching the surface to form a short circuit. However, there is a potential for the electrode to stick the surface, which results in the tungsten being mixed into the weld.

Using a lift arc such as a blast of high frequency that lasts for microseconds is the best solution. It breaks through the electrode to allow current to flow without sticking to the surface.

Portability

The weight, size and design of the TIG welder will make a big difference to how portable the unit is. If it is going to remain within a fixed position, a heavy duty unit is perfect. However, the majority of people will need to use it within various locations and you should therefore pay particular attention to the weight and handles on the welder.

Digital Display & Automatic Features

The latest TIG welders have become far usable compared to the older manual welders. They include automation such as thermal overload protection, digital displays and an array of controls for precision welding.

If you are beginner, these new and improved TIG welders make the process of welding far easier. TIG units are notorious for being difficult to use but automated functionality found on modern welders solve this issue.

Conclusion

Investing into a quality TIG welder will be expensive but worth the money. They are capable of welding a variety of different metals with great accuracy and finish.

All of the recommendations above are suited for beginners to professionals and a range of different budgets. You may be tempted by some of the cheap or unknown branded units but we highly recommend sticking with reputable brands.
