TIG Welding

TIG welding is a commonly used as a high quality welding process. TIG welding has become a popular choice of welding processes when high quality, precision welding is required. In TIG welding an arc is formed between a nonconsumable tungsten electrode and the metal being welded. Gas is fed through the torch to shield the electrode and molten weld pool. If filler wire is used, it is added to the weld pool seperately.

Supagas supplies both Pure Argon andĀ Supa Argon 25 for the TIG welding industry. TIG welding is primarily used for aluminium and stainless steel welding. The thickness of the metal will determine the product which is to be used.


  • Pure Argon for 1 – 3mm thickness
  • Supa Argon 25 for 3 – 6mm thickness

Stainless Steel

  • Pure Argon for 1 – 6mm thickness
  • Supa Argon 25 forĀ 2 – 10mm thickness


Weld more metals and alloys than any other process

TIG welders can be used to weld steel, stainless steel, chromoly, aluminum, nickel alloys, magnesium, copper, brass, bronze, and even gold.

Create high quality, clean welds

With superior arc and weld puddle control, TIG allows you to create clean welds when appearances count. Because the heat input is often controlled by pressing on a foot pedal, similar to driving a car, TIG welding allows you to heat up or cool down the weld puddle giving you precise weld bead control. This makes TIG welding ideal for cosmetic welds like sculptures and automotive welds.

No sparks or spatter

Because only the necessary amount of filler metal is added to the welding puddle, no spatter or sparks are produced (if the metal being welded is clean).

No flux or slag

Because the Argon gas protects the weld puddle from contamination, no flux is required or used in TIG welding and there is no slag to block your view of the weld puddle. Also, the finished weld will not have slag to remove between weld passes.

No smoke or fumes

TIG welding does not create smoke or fumes, unless the base metal being welded contains contaminants or elements such as, oil, grease, paint, lead or zinc.

Weld in all positions

TIG welds can be made in all positions – flat, horizontal, vertical or overhead. Perfect for roll cages
and inside confined areas.
