Release the tension from the Pressure Roller Arm by turning the adjustable Wire Drive Tension Screw in an counterclockwise.
Then to release the pressure roller arm push the tension screw toward the front of the machine which releases the pressure
roller arm (Figure 3-11). With the MIG welding wire feeding from the bottom of the spool (Figure 3-12) 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 3-11). Remove the
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 Velocity contact tip.
Before connecting the work clamp to the work make sure the Electricity Supply is switched OFF.
The electrode wire will be at welding voltage potential while it is being fed through the system.
Keep MIG Gun away from eyes and face.
