Best TIG Welders

What is TIG welding? TIG stands for Tungsten inert gas welding. It is the alternative nomenclature for Gas Tungsten Arc Welding or GTAW. You are free to interchange the two terminologies. Classically, TIG welding is mainly applied in the bonding of aluminum, copper, magnesium, and stainless steel alloys. The reason is that it offers more room for a high purity/quality weld compared to other welding methods.

With this approach, the welder forms an arc between the base metal and a non-consumable electrode purely comprising of tungsten. Its purpose is to form a substantial coalescence between two or more metals. There are various lengths & sizes of non-consumable electrodes. Mostly, they comprise of tungsten alloys or even pure tungsten in addition to other oxides and elements. This is due to the extremely high melting point of tungsten. It has a peak melting point of 3410 C.

If you have the right kind of equipment or experience, you can easily perform Tungsten inert gas welding either through a manual, automatic, or even hybrid procedure. This approach offers numerous solutions, especially in manufacturing challenges. Nevertheless, in instances where the base metals have significant differences in melting points, e.g., copper and steel, tube brazing is a better method in comparison to TIG welding.

TIG welding falls under two categories. They include manual and orbital welding. When performed correctly, both welding methods result in a very high-quality weld at the joint between two metals. Orbital can effortlessly be repeated, thus makes it apposite for automation if necessary. Moreover, it’s a clean process that creates a better weld compared to most other types.

On the contrary, the manual approach is a more meticulous solution allowing for higher accuracy and refining of weldments if orbital welding is not possible. Below is a comprehensive list of 8 of the best TIG welding machines.

Tips for Purchasing the Best TIG Welder

Best TIG Welders for Home or Professional Use

Even though TIG welding offers numerous merits over other categories of welding techniques, it doesn’t mean that it’s an ideal method in all situations. Various considerations should be taken before settling for TIG welding. They include:

What Input Power to Consider?

You need to determine the amount of power required for the job. Also, consider your financial condition as to what you can afford. A hobbyist does not need a highly sophisticated TIG welder. What’s more, if you intend to undertake automatic welding using external software programing and fixture control in addition to an external power source, you need a heavy-duty welder.

The type of metals to be welded is another factor that dictates your machine’s power requirements. A TIG welder aluminum machine requires AC power. The same applies to other minerals, such as magnesium. However, Ferrous metals are typically welded using DC power outputs.

What Is Duty Cycle?

The duty cycle refers to the period you can weld using a specific power output without overheating or burning the source of power. Welding machines manufactured in the USA and some other countries use a duty cycle calculated by means of a standard time of 10 minutes.

If you own an enthusiast-type TIG welder, then the appropriate duty cycle would be around 20 percent. Nevertheless, an automated TIG setup might need a duty cycle worth 100 percent. This is due to the capability to weld for extended periods. For most handheld TIG procedures, duty cycles ranging between 40 and 60 percent are, in most cases, adequate, especially in industry and construction.

Does Size & Weight Matter?

Best TIG Welders for Home or Professional Use

In case you are purchasing a device that will always be stationary, size and weight might not be an issue. However, if the power source would be shifted around the workshop, or if welding is supposed to occur outdoors, then portability is a significant factor.

Nowadays, some inverters enable the use of light and small machines. They usually weigh about 10 pounds. They also operate between 115 and 230 volts. For situations where there is a lack of access to primary power, you can opt for an engine-driven machine. 

This can significantly assist you in in-field maintenance procedures, construction work, and pipe welding, among others. Still, the majority of engine-driven machines are capable of generating electrical power.

Digital Display

A welder TIG with a digital display can significantly enhance your welding experience. Some portable welders come with LCD displays in which various kinds of information are displayed. These include the temperature, duty cycle, voltage, current, etc. all these make the welding process a lot more accurate and simple. 

If you have a 2-in-1 or 3-in-1 welder, the display will indicate the welding type to ensure that you do not accidentally use the wrong type. A good example is the Eastwood TIG 200 digital AC/DC welder.

Concluding Remarks

Through the above list, it is my belief that you are now in a better position to make the right choice while looking for a TIG welder either for light or heavy use. You also need to know that TIG welding is suitable for numerous types of metals. What’s more, it delivers some of the strongest and cleanest welds. Typically, TIG does not produce sparks, slag, spatter, fumes, or smoke. Just ensure that the metal surface is clean. You can also utilize TIG in cramped spaces or overhead without being under the shower of slag and sparks.

Besides, knowing the best gas for welding is also critical. Argon gas is appropriate for almost all kinds of TIG welding. Sometimes, Helium is utilized when more penetration is needed, or for faster welding with a high-temperature arc.

Also, for best results, it is essential to understand lift-arch, scratch start, and high-frequency start. A scratch start refers to the act of scratching a welding surface with the heated electrode in order to complete the circuit. High-frequency start refers to the use of a high-frequency alternating current at the beginning of welding. 

The aim is to override any resistance and cause an electrical jump in the gap between the work surface and the torch. Lastly, lift-arc is a methodology used in case the HF will possibly cause electromagnetic interference to electronic devices. What are your personal preferences when choosing a TIG welder? Does your setup determine the kind of welder you buy? Do you consider power infrastructure when buying welders?
