Maintenance & Servicing

General Maintenance

This welder has been engineered to need minimal service providing that a few very simple steps are taken to properly
maintain it.
1. Replace INPUT POWER CABLE (8), ground cable, ground clamp, or torch/electrode cable when damaged or
worn.
2. Avoid directing grinding particles towards the welder. These conductive particles can build up inside the machine
and cause severe damage.
3. Periodically clean dust, dirt, grease, etc. from your welder. Every six months or as necessary, remove the side
panels from the welder and use compressed air to blow out any dust and dirt that may have accumulated inside
the welder.
WARNING: DISCONNECT FROM POWER SOURCE WHEN CARRYING OUT THIS
OPERATION.
4. Check all cables periodically. They must be in good condition and not cracked.
WARNING: ELECTRIC SHOCK CAN KILL!
not remove power from all internal circuitry in the welder. To reduce the risk of electric shock, always unplug the
welder from its AC power source and wait several minutes for electrical energy to discharge before removing side
panels.

Check for obstructions blocking air flow
and ensure that there are 12 inches of

vents on all sides of the machine.
Check the voltage of your outlet. If it
is 10% more or less than 120V, call a
qualified electrician.
