Fronius TTB 160 G Manual De Instrucciones página 42

NOTE!
The welding current specifications for torch bodies TTB 160 G, TTB 220 G, and
TTB 260 G apply only from a torch body length L ≥ 65 mm.
When using shorter torch bodies, the welding current is reduced by 30%.

NOTE!
For torch bodies TTB160 G, TTB 220 G, and TTB 300 W, the specified welding cur-
rent only applies when using standard wearing parts.
When using gas lenses and shorter gas nozzles, the welding current is reduced.
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.
