MAINTENANCE

WARNING
ELECTRIC SHOCK can kill.
• Turn the input power OFF at the welding
power source before installation or
changing drive rolls and/or guides.
• Do not touch electrically live parts.
• When inching with the gun trigger, electrode and drive
mechanism are "hot" to work and ground and could
remain energized several seconds after the gun trigger
is released.
• Do not operate with covers, panels or guards removed
or open.
• Only qualified personnel should perform maintenance
work.

ROUTINE MAINTENANCE

Periodically blow out or vacuum any metal wire shavings from
Drive Roll area.
Inspect and replace any worn wire on inlet guide or barrel liner.
NOTE: Oil and spray cleaners can contaminate electrode wire and
cause bad welds. They could also make wire drive rollers slip. Be
careful when using any of these liquids on spool gun.
Carefully clean gun with a cleaner that is safe for plastic. Apply
cleaner to rag and wipe gun. Do NOT spray cleaner on gun. Keep
cable dean. Oil, grease gasoline, paint, and solvents degrade cable
insulation.
Routine maintenance for consumable spare parts will depend
on Duty Cycle and particular application.
