TIG Welding

What is TIG Welding

Tig welding, is an arc welding process that uses a non-consumable tungsten electrode to produce the weld.


The weld area and electrode are protected from oxidation or other atmospheric contamination by an inert shielding gas (argon or helium). A filler metal is normally used, though some welds, known as autogenous welds, or fusion welds.


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. Tig welding 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, Tig Welding 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.


Parweld XTT 212Di AC/DC Pulsed

The XTT 212Di single-phase AC/DC Pulsed TIG Inverter is capable of HF TIG, Lift TIG, and MMA welding. This dual voltage (110V/230V) compact and lightweight machine has a multi-language digital user interface, which rapidly gets you to the correct machine setting with minimal process knowledge, on site or in the workshop.


Advanced settings for each process can be accessed from the front panel. There is also a memory option that allows you to save and recall up to 6 welding jobs. The XTS 908 Unit Attachment allows for the option of water cooling the TIG Power Source Machine. Compatible with optional Foot Control device.
