5.05 Inserting Wire into the Wire Feed Mechanism
Release the tension from the pressure roller by turning the adjustable wire drive tension screw in an anti-
clockwise direction. Then to release the pressure roller arm push the tension screw toward the front of the
machine which releases the pressure roller arm (Figure 5-6). With the MIG welding wire feeding from the
bottom of the spool (Figure 5-7) pass the electrode wire through the inlet guide, between the rollers, through
the outlet guide and into the MIG torch. Re-secure the pressure roller arm and wire drive tension screw and
adjust the pressure accordingly (Figure 5-6). Remove the contact tip from the MIG torch. With the MIG Torch
lead reasonably straight, feed the wire through the torch by depressing the trigger switch. Fit the appropriate
contact tip.
WARNING
Before connecting the work clamp to the work make sure the mains power supply is switched off.
The electrode wire will be at welding voltage potential while it is being feed through the system.
Keep Mig Torch away from eyes and face.
