5.3 MIG/MAG welding
5.3.1 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 coo-
lant 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 5.1.3.2 chapter.
• When using a gas-cooled welding torch, use a hose bridge to establish the coolant cir-
cuit > see 9 chapter.
