SYSTEM MAINTENANCE
Power Supply
This unit is equipped with a fresh air intake filter. This filter should be replaced on a semi-annual basis. If the environment is
particularly dirty, the filter should be replaced more frequently.
On an annual basis, the unit should be opened up and thoroughly blown out so it is free of all contaminants.
Welding Tool
Typically, most trouble stems from the stud weld tool. The stud weld tool should be serviced once every quarter. Monthly
service may be required if use is exceptionally heavy. Please refer to the stud weld tool service manual for maintenance
guidelines and instructions.
Cables
Cables can be a frequent source of trouble. Users often drag the power supply around by the cables. This can damage
cables. Whenever the weld tool service is performed, the cables should be visually inspected for worn / damaged insulation
or fraying wire. If the cables are damaged they should be repaired to prevent any degradation of weld quality and to protect
operator safety.
BUILT IN EQUIPMENT SAFETY
A fault in the welding power supply can create a potentially dangerous condition. The microprocessor continually monitors
the system for faults and shuts the unit off when one is detected.
This is done for operator and equipment safety purposes.
The unit can be restarted, but will shut down again as soon as the fault condition is detected. The unit must be repaired.
Serious faults, resulting from component failure, disable the unit for operator safety.
