SAFETY PRECAUTIONS
WARNING
Observe all additional Safety Guidelines detailed
throughout this manual.
ELECTRIC SHOCK can kill.
• Do not touch electrically live parts such
as output terminals or internal wiring.
• When inching with gun trigger, electrode and
drive mechanism are “hot” to work and
ground and could remain energized several
seconds after the gun trigger is released.
• Turn OFF input power at welding power
source before installation or changing
drive roll and/or guide tubes.
• Welding power source must be connected
to system ground per the National
Electrical Code or any applicable local
codes.
• Only qualified personnel should
perform maintenance work.
ROUTINE MAINTENANCE
• Check weld cables, control cables and gas hoses
for cuts.
• Clean and tighten all weld terminals.
• Inspect and clean drive rolls and inner wire guide
and replace if worn.
PERIODIC MAINTENANCE
• Blow out or vacuum the inside of the feeder.
• Every six months check the motor brushes.
Replace them if they are less than 1/4" long.
• Every year inspect the gearbox and coat the gear
teeth with a moly-disulfide filled grease. DO NOT
use graphite grease.
CALIBRATION SPECIFICATION
All calibration is factory set on the POWER FEED ®
10M Single Wire Feeder.
To verify the wire feed speed:
• Assemble a .045 (1.2mm) drive roll kit into the
POWER FEED ® 10M Single Wire Feeder.
• Load a spool of .045 (1.2mm) electrode and thread
the electrode through the wire drive.
• Adjust the wire feed speed to 300 in/min
(7.62m/min).
• Press the COLD FEED switch and measure the
actual wire feed speed with a calibrated wire feed
speed tachometer.
• The measured wire feed speed should be within
±2% of the set value.
