The Xcel-Arc Welding NZ was founded in 1994 in New Zealand. [2] It provides plasma cutters, TIG-welding, MIG, [3] Arc welding machines, machine trolleys, [4] and protective gear. [5] [6] Xcel-Arc manufactures machines that comply Australian-New Zealand market standards AS/NZS60974-1 and EN 50199.
Arc welding power supplies can deliver either direct (DC) or alternating (AC) current to the work, while consumable or non-consumable electrodes are used. The welding area is usually protected by some type of shielding gas (e.g. an inert gas), vapor, or slag. Arc welding processes may be manual, semi-automatic, or fully automated.
