Maintenance work, intervals
6.2.1
Daily maintenance tasks
• Blow compressed air through the wire feed from the direction of the welding torch central connector.
• 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.
• Mains supply lead and its strain relief
• Welding current cables (check that they are fitted correctly and secured)
• Gas tubes and their switching equipment (solenoid valve)
• Gas cylinder securing elements
• Operating, message, safety and adjustment devices (Functional test)
• Other, general condition
6.2.2
Monthly maintenance tasks
• Casing damage (front, rear and side walls)
• Selector switches, command devices, emergency stop devices, voltage reducing devices, message
and control lamps
• Check coolant tubes and their connections for impurities
• Check that the wire guide elements (inlet nipple, wire guide tube) are fitted securely.
• Check that all connections and wearing parts are hand-tight and tighten if necessary.
• Check the wire guide.
• 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 that all screw and plug connections and replaceable parts are secured correctly, tighten if
necessary.
