WIG/tIG = in opposition to the metals welding in MIG/MAG gas cur-
tain, during welding with WIG method, the electric arc appears between
the infusible wolframic electrode and the welded material. For the pro-
tection of the wolframic electrode and the fusion weld, the neutral gases
as argon or helium or non-oxidizable gas mixtures are used. Welding
with WIG method may be used for all welded metals. Selection of the
type of current, polarization and curtain gas depends on the welded
metal type. This device uses the welding handle (burner) – WIG, which is
equipped with the wolframic electrode, argon curtain gas release nozzle
and the fluxing agent, depending on the welded material. Our welding
technology specialists recommend red wolframic electrodes for steel
and precious steel, green ones for aluminum, black ones for steel and
cast iron, gold and grey ones for universal applications. Depending on
the metal plate thickness, the following wolframic electrodes are re-
commended:
thin metal plate 0.5-1 mm
metal plate, thickness of 1-6mm
thick metal plate - 6 mm
= electrode 1.6 mm = electrode 2.4 mm = electrode 3.2 mm
In case of gas nozzles we recommend the size of 7 in within the area of
universal applications and size of 5 within the area of precise welding.
