Technical data

General

This product meets the requirements set out in standard IEC 60974-7.
The welding current specifications only apply when using the standard wearing
parts.
When using gas lenses and shorter gas nozzles, the welding current is reduced.
For gas-cooled torch bodies, the welding current specifications only apply from a
torch body length L ≥ 65 mm.
When using shorter torch bodies, the welding current is reduced by 30%.
When welding at the power limit of the welding torch, use larger tungsten electrodes
and gas nozzle opening diameters in order to increase the service life of the wearing
parts.
Take into account amperage, AC balance, and AC current offset as performance-enhanc-
ing factors.
