Threading the wire and adjusting tightness
When changing the welding wire, the pressure arms need to be released. Ensure that the
groove of the feed rolls matches the diameter of filler wire used. Release the wire end
and cut off any deformed section before pulling it out from the wire feeder. Straighten
about 20 cm of the new filler 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.
Present the filler wire tip to the back of the wire feed rolls and press the wire inch button
on the wire feed front panel. Feed the wire to the gun contact tip and prepare to weld.
