Repair
er
• Check and clean the welding torch. Deposits in the welding torch may
cause short circuits, impair the welding result and lead to welding torch
damage!
• Check wire drive, welding torches, and liner elements for application-
related equipment and setting.
• Clean the wire feed rolls on a regular basis (depending on the degree
of soiling). Replace worn wire feed rolls.
• Connections of the welding current leads (check for tight and locked
seating).
• Is shielding gas cylinder with gas cylinder securing elements
(chain/belt) secured?
• Strain relief: Are hose packages secured with strain relief?
• Checking all supply lines and their connections (pipes, hoses, hose
packages) for damage or leaks.
• Checking the welding system for damage to the housing.
• Transport elements (strap, lifting eyes, handle, wheels, parking brake)
corresponding safety elements (if necessary fuse caps) are present
and flawless?
• Cleaning connections of coolant pipes (quick connect coupling,
connections) from impurities and install protective caps when not in
use.
• Gas test that the solenoid valve opens and closes properly.
• Checking operating, signalling and indicator lights, protective devices
and actuators.
• Check wire feed roll holder (wire feed rolls must be firmly seated on
their holders and must not have any play)
• Cleaning dirt filter (if applicable)
• Checking correct mounting of the wire spool.
• Clean external surfaces with a damp cloth (do not use aggressive
cleaning agents).
• Cleaning the power source (inverter)
• Cleaning heat exchanger (torch cooling)
• Coolant change (torch cooling)
• Periodic inspection and testing
• The coolant must be checked using the appropriate frost protection tes-
ter TYP 1 (KF) or FSP (blueCool) for sufficient frost protection and re-
placed if necessary (accessories).
