MAINTENANCE
The unit is maintenance-free. The following points should be checked regularly:
• Mains plug and cable as well as the welding torch and earth connection from time to time for
damage.
• After every package of electrodes or after 30-40 hours of TIG welding operation, blow out
the unit with dry compressed air at low pressure. For this purpose, switch off the unit and
pull the mains plug. Blow the compressed air from the front through the ventilating grill to the
rear. Leave the housing closed. Never blow the compressed air through the grill on the rear
of the unit. A ventilating fan is located there that would be brought to such a high rotating
speed by the compressed air that the bearing could be damaged.
