4.11 Inserting Wire into Feed Mechanism
WARNING
ELECTRIC SHOCK CAN KILL! Make certain the input power is disconnected from the power source before
proceeding. Do not reattach the input power until told to do so in these instructions.
WARNING
MOVING PARTS can cause injury.
1. Swing the Pressure Adjusting Knobs down and the two Pressure Roll Arms automatically spring up. If tension
has been previously set, the adjusting knob will have to be loosened to be able to swing the knob down.
2. Make sure the end of the wire is free of any burrs and is straight. Pass the end of wire through the Input Wire
Guide and over the Feed Rolls. Make certain the proper groove is being used.
3. Pass the MIG wire over the feed roll groove and out past the MIG Gun Adaptor. Then fit the MIG Gun as per
Section 4.05 ensuring the MIG wire passes into the MIG Gun liner of the MIG Gun.
4. Lower the Pressure Roll Arms.
5. Swing the Pressure Adjusting Knobs back into place.
6. Use the Pressure Adjusting Knobs to create a “snug” condition. (Clockwise to tighten and Counter Clockwise
to loosen).
7. Turn ON the power supply. Set proper WFS and remove the tip from the welding gun. Depress INCH button
until the wire reaches the top of welding gun. Tighten the tip again and finish inserting wire.

4.12 Feed Roll Pressure Adjustment
The roll on the swing arm applies pressure to the grooved roll via an adjustable tension device. The pressure adjusting
knobs should be set to a minimum pressure that will provide satisfactory wire feed without slippage. If slipping occurs,
and inspection of the wire out of the MIG Gun reveals no deformation or wear, the conduit liner should be checked
for kinks or clogging from metal flakes. If this is not the cause of slipping, the Feed Roll pressure can be increased
by rotating the pressure adjusting knobs clockwise. The use of excessive pressure may cause rapid wear of the Feed
Roll, motor shaft and motor bearings.
