3.12 Inserting Wire into the Wire Feed Mechanism
Release the tension from the Pressure Roller Arm by turning the adjustable Wire Drive Tension Screw in a counterclockwise. Then
to release the pressure roller arm push the tension screw toward the front of the machine which releases the pressure roller arm.
With the MIG welding wire feeding from the bottom of the spool (Figure 3-10) pass the electrode wire through the inlet guide,
between the rollers, through the outlet guide and into the MIG Gun. Re-secure the pressure roller arm and wire drive tension screw
and adjust the pressure accordingly (Figure 3-9). Remove the nozzle and contact tip from the MIG Gun. With the MIG Gun lead
reasonably straight, feed the wire through the MIG Gun by depressing the trigger switch. Fit the appropriate contact tip.
