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 inner liner

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.
