Description
Is an argon/helium based mixtures and are inert, non-toxic, colourless and odourless. Supplied in high pressure metal cylinders.
Is used in GMAW and GTAW for aluminium and aluminium alloys (Argon 75 above 6mm).
Produces a hotter arc, giving the best penetration, defect free weld beads with low porosity at high production levels.
