SAFETY PRECAUTIONS
GENERAL MAINTENANCE
1. The fan motor has sealed bearings which require
no service.
2. In extremely dusty locations, dirt may restrict the
cooling air causing the welder to run hot with pre-
mature tripping of thermal protection. Blow out the
welder with low pressure air at regular intervals to
eliminate excessive dirt and dust build-up on inter-
nal parts.
3. Periodically check the welding cables. Inspect for
any slits or punctures. Also make sure that all con-
nections are tight.
ELECTRIC SHOCK can kill.
• Only qualified personnel should
perform this maintenance.
• Turn the input power OFF at the
disconnect switch or fuse box
before working on this
equipment.
• Do not touch electrically hot
parts.
