Before fitting a torch body, ensure that the interface between the torch body
and the hosepack is clean and undamaged.
In the case of water-cooled welding torches, increased resistance may arise
when tightening the union nut due to the construction of the welding torch.
Always tighten the union nut on the torch body as far as it will go.
Ensure that the union nut is tightened as far as it will go.
If a gascooled welding torch is used with a plastic inner liner and bronze in-
ner liner insert instead of a steel inner liner, the performance data specified
in the technical data is reduced by 30%.
To operate gascooled welding torches at maximum power, replace the 40 mm
(1.575 in.) inner liner insert with the 300 mm (11.81 in.) inner liner insert.
The torch body is in the 0° position
when the dowel pin (1) on the ho-
sepack engages in the locating hole (2)
in the torch body.
