4.1.4 Feeding the filler wire
Ensure that the groove of the feed roll matches the diameter of ller wire used. Release
the wire end from the spool and cut o any deformed section. Be careful the wire does
not spill from the spool sides
1. Connect the welding gun and tighten the collar.
2. Straighten about 20 cm of ller wire and ensure the tip has no sharp edges. File if
necessary, as a sharp wire edge may damage the wire gun liner – particularly softer
plastic liners.
3. Present the ller wire tip to the back of the wire feed rolls and press the wire inch
switch on the wire feed panel. Feed the wire to the gun contact tip and prepare to
weld.
4. Press the Wire Inch button and allow the ller wire to feed through the gun cable to
the contact tip.
