at the welding power source.
2. Open the wire drive door by pulling on the top.
3. Remove the outer wire guide.
4. Remove drive rolls by pulling straight out. It may be
necessary to wiggle the drive roll to free it from the
snap ring.
5. Remove the inner wire guide.
6. Install the new inner wire guide, with the arrow
pointing in the direction of wire travel.
7. Install the drive rolls and outer wire guide.
8. Close the wire drive door and adjust the pressure
setting accordingly.
Wire Drive Pressure Setting
(See Figure #10)
Most wires operate well with a pressure setting of “2”.
The best drive roll pressure varies with wire type, wire
surface, lubrication and hardness. Too much pressure
may crush the wire or cause "birdnesting", but too little
pressure could cause slippage.
Set the drive roll pressure by:
1. Press the end of the gun against a solid object that
is electrically isolated from the welder output and
press the gun trigger for several seconds.
2. If the wire "birdnests" or jams, the drive roll pressure
is too high. Reduce the pressure by one turn of the
knob, run new wire through the gun, and repeat step
1.
3. If the only result is slippage, disconnect the gun and
pull the gun cable forward about 6" (150mm). There
should be a slight waviness in the exposed wire. If
there is no waviness, increase the pressure setting
one turn, reconnect the gun and repeat the above
step electrode lead to the gun adapter.
