10. MAINTENANCE
10.1 MAINTENANCE
Regular inspection and cleaning reduces the necessity
for maintenance operations and will keep your tool in
good working condition.
Warning: Remove the plug from the power supply.
Periodically the welder must be checked as detailed
below.
• Check the torch cable and ground cable connections.
• Clean the contact tip and the gas shroud with an iron
brush. Replace if worn.
• Clean the outside of the welder with a damp cloth.
• Every time the wire spool is replaced:
• Check the alignment, cleanliness and state of wear
of the wire roll.
• Remove any metal powder deposited on the wire
feeder mechanism and then dry with compressed air.
• Occasionally test to ensure the thermal cut-out
device is operating correctly, i.e. weld for an
extended period or on a maximum duty cycle.
• Check the condition of the warning labels.
• Replace any worn parts.
• If the replacement of the supply cord is necessary,
this has to be done by the manufacturer or his agent
to avoid a safety hazard.
The welder must be correctly ventilated during tool
operation. Avoid blocking the air inlets and vacuum the
ventilation slots regularly.
Do not use solvents or fuels to clean the product. When
not in use, store the product in a safe, dry place.
