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 connect-
ed 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.
