Technical data

General

This product meets the requirements set out in standard IEC 60974-7.
NOTE!
The performance data specifications only apply when using standard wearing
parts.
When using gas lenses and shorter gas nozzles, the welding current is reduced.
NOTE!
The welding current specifications apply to gas-cooled torch bodies only from a
length of 65 mm (2.56 in.).
When using shorter torch bodies, the welding current is reduced by 30%.
NOTE!
When welding at the power limit of the welding torch, use larger tungsten electro-
des and gas nozzle opening diameters to increase the service life of the wearing
parts.
Take amperage, AC balance, and AC current offset into account as performance-enhan-
cing factors.
