• 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 sec-
onds after the gun trigger is released.
• Do not operate with covers, panels or guards
removed or open.
• Only qualified personnel should perform mainte-
nance work.

WARNING
LOADING SPOOLS OF WIRE
• Keep hands, hair, clothing and tools
away from rotating equipment.
• Do not wear gloves when threading wire
or changing wire spool.
• Only qualified personnel should install, use or
service this equipment.
------------------------------------------------------------------------
SPOOL RETAINER
Whenloadingandremovingthe8”spoolsmakesure
that the wing nut (inside the wire reel spindle hub) is
turned 90° from the wire reel spindle locking tabs. If
thewingnutispositionedinlinewiththelockingtabs,
the tabs cannot be depressed to load or unload the
wirespool.(SeeFigA.2)
The wire spool must be pushed all the way on the
spindle so that both the spindle’s tabs will hold it in
place. The wire spool will rotate counter clockwise
whenwireisde-reeled.
SPOOL BRAKE
Adjust the spool brake with wire spool installed, to
provide enough friction to stop wire overrun. To
adjust the brake turn the wing nut clockwise to
increase the brake, and counterclockwise to loosen
thebrake.
