Technical data
General
This product meets the requirements set out in standard IEC 60974-7.
NOTE!
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.
NOTE!
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%.
NOTE!
When welding at the power limit of the welding torch, use larger tungsten electro-
des 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-enhan-
cing factors.
