5.1.10 Welding torch connection
Equipment damage due to improperly connected coolant pipes!
If the coolant pipes are not properly connected or a gas-cooled welding torch is used, the coolant
circuit is interrupted and equipment damage can occur.
• Connect all coolant pipes correctly!
• Completely unroll the hose package and the torch hose package!
• Observe maximal hose package length > see 5.1.8.2 chapter.
• When using a gas-cooled welding torch, use a hose bridge to establish the coolant
cuit > see 9 chapter.
Prepare welding torch according to the welding task in hand (see operating instructions for the torch).
