TIG Welders Buyer’s Guide
There’s a lot of technical terms being thrown around in these reviews, so it may benefit you to brush up on some of the features to look for when purchasing the TIG welder for your needs. Here’s a quick breakdown of some terms you’ll often see and how they relate to your TIG welding experience.
Ac/Dc Operation: The power source plays a vital role in determining what kinds of metals and applications you can use. For example, if you plan to work with aluminum–which most users should–AC power is essential.
Amperage Range: Wider amperage ranges allow for you to perform welding operations from super-fine to deep penetration. Amperage ranges are expressed for both AC power as well as DC power. The better machines have the widest amperage ranges.
Multiple Types Of Welding Applications: Metal inert gas welding (MIG) involves an arc being formed between the metal and a wire electrode that is consumed and fused to the metal. It is more commonly used for heavy steel applications. Stick welding is similar except that the wire is coated with a flux that prevents contaminants from mixing with the weld. Tungsten inert welding (TIG) uses nonconsumable tungsten to create an arc and is especially useful with aluminum and thin metals. Some welders are dedicated to TIG only while many others allow the operator to use stick, TIG and MIG welding applications.
Duty Cycle: Duty cycle is measured in ten-minute increments and determines how long within that period a welding machine can produce a certain amperage. For example, a machine rated at 140 A @ 35% means that it can reduce that amount of amperage approximately for three minutes without overheating. The higher the percentage, the longer it can maintain a particular amperage–usually read from the machine’s maximum amperage. Duty cycle determines how efficiently your work time can be.
Precision Control: Most machines in low price ranges have limited precision management capability. Precision is obtained by use of a foot pedal that controls amperage while you work and through pulse control technology that automatically control amperage within parameters the user sets. Increased precision means the higher quality workmanship.
