6.2 Maintenance work, intervals
6.2.1 Daily maintenance tasks
Figure 6-1
• Purge the wire guide from the direction of the Euro torch connector with oil- and condensate-free com-
pressed air or shielding gas.
• Check that coolant connections are tight.
• Check that the welding torch, and where applicable the power source cooling, are functioning cor-
rectly.
• Check the coolant level.
• Check whether there is the O-ring on the gas nipple of the Euro torch connector and whether it is not
damaged. Replace defective O-ring.
• Check torch, hose package and power connections for exterior damage and replace or have repaired
by specialist staff as necessary!
• Check the wearing parts in the torch.
6.2.2 Monthly maintenance tasks
• Check the coolant container for sludge deposits and check the coolant for cloudiness.
Clean the coolant container if contaminated, and change the coolant.
• If the coolant is dirty, rinse through the welding torch alternately several times with fresh coolant using
the coolant return and supply.
• Check that all connections and wearing parts are hand-tight and tighten if necessary.
• Check and clean the welding torch. Deposits in the torch can cause short circuits and have a negative
impact on the welding result, ultimately causing damage to the torch.
• Check the wire guide.
• Check that all screw and plug connections and replaceable parts are secured correctly, tighten if ne-
cessary.
6.3 Maintenance work
Electric current!
Repairs may only be carried out by authorised specialist staff!
• Do not remove the torch from the hose package!
• Never clamp the torch body in a vice or similar, as this can cause the torch to be irreparably
destroyed!
• If damage occurs to the torch or to the hose package which cannot be corrected as part of
the maintenance work, the entire torch must be returned to the manufacturer
