Punair TIG Welding Machines

TIG welding offers many advantages over other welding processes, such as higher precision, better appearance and ability to weld thinner materials. Our range of TIG welders covers professional machines with high duty cycle, to capable, compact machines for the hobbyist - and they support mma welding too.

Something You Should Know about TIG

Gas tungsten arc welding (GTAW), also known as tungsten inert gas (TIG) welding, is an arc welding process that uses a non-consumable tungsten electrode to produce the weld. The weld area and electrode is protected from oxidation or other atmospheric contamination by an inert shielding gas (argon or helium), and a filler metal is normally used, though some welds, known as autogenous welds, do not require it. When helium is used, this is known as heliarc welding. A constant-current welding power supply produces electrical energy, which is conducted across the arc through a column of highly ionized gas and metal vapors known as a plasma. GTAW is most commonly used to weld thin sections of stainless steel and non-ferrous metals such as aluminum, magnesium, and copper alloys. The process grants the operator greater control over the weld than competing processes such as shielded metal arc welding and gas metal arc welding, allowing for stronger, higher quality welds. However, GTAW is comparatively more complex and difficult to master, and furthermore, it is significantly slower than most other welding techniques. A related process, plasma arc welding, uses a slightly different welding torch to create a more focused welding arc and as a result is often automated.

The Popular Punair Led TIG Welders

A new generation of TIG200 series intelligent TIG welder, breaking the traditional design concept, adopting advanced digital control, and simple adjustment of welding parameters. The operation panel is equipped with high-definition LED smart screen display.In the argon arc welding mode, the welding current is automatically matched to the thickness of the plate. And the front and post gas time can be set separately to better protect the tungsten needle and make sure the arc more stable. In the spot welding mode, the spot welding time and the rest time is adjustable can also be set individually to meet the requirements of high appearance and deformation.
