Fit a spool of appropriate wire onto the spool so that it turns
clockwise as the wire is fed.
Carefully release the end of the wire from the spool ensuring that
the released end is held to stop the wire from unravelling. Cut off
the end kink to give a smooth straight end of wire.
Obtain a gap between the wire feed roll and the pressure roll
by lifting the cam latch. Feed the wire end into the guide tube,
between the drive rolls, and into the "Euro" connector guide until it
protrudes about 20mm out of the front of the "Euro" connector.
Close the drive rolls by lowering the cam latch ensuring the
rolls firmly hold the wire. Adjust the tension so that wire feeds
smoothly. Do not over tighten.
Fit the gun and cable assembly onto the "Euro" connector by
slipping the end of wire into the cable wire hole.
Tighten the "Euro" connector lock ring.
Activate the power source; set the wire feed speed to 4 on the dial
and press the gun trigger or wire inch push button (if fitted). The
wire feed roll should turn, feeding the wire further up the gun and
cable assembly. Ensure there are no kinks or sharp bends in the
gun cable and hold the gun trigger or wire inch button until the
wire emerges from the gun. It is good practice to remove the tip
when first feeding a new coil of wire, then refitting over the wire
and tightening. Cut off the end of the wire leaving 10mm to 15mm
stick-out. Select required polarity. See Section 1.5
