SAFETY PRECAUTIONS
WARNING
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.
Observe all additional Safety Guidelines detailed throughout this manual.
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.
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.
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
