GUN INSPECTION AND UPKEEP

WARNING: ELECTRIC SHOCK can kill; FLY-
ING FLUX PARTICLES can puncture eyes
and skin; WELDING WIRE can cause punc-
ture wounds.
•
Do not touch live electrical parts.
•
Shut down welding power source and wire
feeder and be sure they cannot be accidental-
ly energized before inspecting, maintaining,
or servicing gun.
•
Close air valve, bleed pressure from tank,
and disconnect air supply.
Usage and shop conditions will determine frequency
and type of maintenance required. At minimum, inspect
equipment every three months as follows:
1.
Inspect gun for broken areas, cracks and loose
parts; tighten, repair and replace as required.
2.
Carefully remove any weld spatter or foreign mat-

TICLES can injure personnel and damage
equipment.
•
Point gun liner only in a safe direction away
from personnel and equipment when clean-

IMPORTANT: Flux is very abrasive and has a wearing
and clogging effect on all parts and pieces exposed to it.
Good maintenance is essential for proper operation.
Usage and shop conditions will determine frequency
and type of maintenance required. At minimum, inspect
equipment every three months as follows:
1.
Using a soft brush or cloth, clean dirt and flux par-
