TIG Welder Buying Guide

Surely, inverter TIG welder reviews are helpful for any probable buyer of such equipment, especially for the first-time buyers and operators. However, there are more things that should be considered when shopping for this machine. Below are additional buying factors that you will find equally essential to the product reviews.

Amperage Range

The amperage range is an important factor to consider when choosing TIG welding machines. It is essential to pick a model with the widest amp range, yet at a reasonable cost. TIG welders with too narrow amp range can limit the varieties of materials that you can weld. However, an equipment with an amp range of 5-amp to 230-amp can provide the utmost flexibility necessary in welding thinner materials like 24-gauge stainless steel and up to a ¼-inch thin aluminum.

Keep in mind that aluminum materials require higher amp ranges that stainless or mild steel. So, a machine that is incapable or reaching at least a 200-amp will restrict the max thickness of aluminum materials that you can work on. With a wider amp range, the machine will be more useful in different applications, without having to buy other equipment.

Low Amp Welding Performance

Aside from a wide amp range, it is also important to pick a model with good arc stability, say below a 10-amperage. Such feature allows for an easier start, better arc control, including an exceptional fill capability through the weld’s end. While TIG welding is a process performed on thin materials, you will desire for an arc without hot start or lots of high frequency.

There are some models that claim to have great starting designs, those that help in establishing the arc; however, these claims only produce a hot start. The best TIG welder for aluminum should never create a hot start, because the equipment actually spikes up towards a higher amp and a higher starting amp might create a too intense arc, burning through the material, instead of just joining them together.

A hot start is not helpful when it comes to arc stability during a welding process. It does not help the operator too in maintaining good arc control during a crater filling. Stability at low amperage is very critical, while finishing the weld, which is equally an essential nature of TIG welding.

AC/DC Welding

The AC/DC options are very useful if you are planning on welding not just stainless steel or mild steel materials. Also known as Alternating Current and Direct Current respectively, these options offer greater versatility when it comes to the TIG welding machines. An AC TIG welder, for instance, is used with self-oxidizing soft metals such as magnesium and aluminum. The DC option is useful with hard metals like deoxidized copper, stainless steel, and steel.

Metal Thickness

When choosing the right TIG welder, it is also crucial to consider the thickness or thinness of the material that you are working on. Remember that this machine is highly efficient with thin metals that require precise heat control. Therefore, working with a ½-inch thickness is impossible with the use of a TIG welder.

Duty Cycle

The duty cycle largely depends on the amperage you are requiring for the weld. When it comes to this feature, a 20% duty cycle is said to be low, while a 40% and 50% duty cycles are in the medium category, while 60% to 80% duty cycle are considered high.

Control System

The control system, primarily the heat control is another crucial factor for a great TIG inverter. This feature, again, is very useful when working with thin materials, allowing you to control the heat input so as to reduce the metal’s war page. A pulse weld feature is a reliable option of controlling the heat input without compromising the weld penetration. A pulsed TIG welder tends to alternate between low background current and a high peak current, maintaining the arc and allowing the weld to cool down.

The best AC DC TIG welder should have such built-in feature, providing a reliable heat input control. Such option is also a famous training tool, which can be adjusted, helping the operator to time the filler metal application into the weld puddle. In short, a TIG-pulser helps in achieving a constant-looking ‘stacked dime’ weld bead that is associated with great TIG welds.

Ease of Use

Of course, a dependable TIG welding machine is not only versatile and flexible, but also offers a user-friendly interface. This feature is most important among the beginners in the welding field. While TIG welding procedures are oftentimes associated with complexities, the machine itself does not need to be that complicated.

Fortunately, the reliable brands today, especially the featured products in this article provide easy-to-understand controls and an overall design. Some key accessories you might to consider include a metal foot pedal amp control that simplifies the process by letting the operator either decrease or increase the welding amp when necessary. Hand amp controls also exist, but the former design is said to be more convenient.

Overall Design and Quality

The overall design and quality of the best inverter TIG welder are likewise associated with additional features. These designs usually contribute to the service life span and the durability of the entire machine. A few of the key features worth-considering include a cooling fan or a cooling system and a removable TIG torch. One of the featured models above boasts an automatic cooling system, which activates only when necessary.


In a nutshell, selecting a reliable TIG welder is essential because this type of equipment is very useful in different applications and purposes, ranging from home improvement projects to automotive applications, maintenance and repair works, industrial and construction fields and more.

Getting the best AC DC TIG welder is equally crucial as this welding machine can be a long-term investment, and maximizing its potentials and usefulness for the longest possible time will be worth your money, without a doubt. And, in order to arrive at the best TIG welder, it is wise to consider the featured products presented in this review, including the buying guide for an additional deciding factor.
