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.
