• Make sure that groove of feed roll match the diameter of welding wire used. Feed roll
groove is selected by moving the groove selecting washer (28). Also the selector plate
for changing the feed roll groove has to be moved similarly. (see table on page 4).
• Release the wire end from reel and cut off the bent length. Be careful that the wire does
not spill from the reel to sides!
• Straighten about 20 cm of the wire and see that the end of it has no sharp edges (file
off if necessary). A sharp edge may damage the wire guide tube and contact tip of the
welding gun.
• Draw a bit of loose wire from wire reel. Feed wire through back liner to feed rolls. Don't
release pressure of feed rolls!
• Press the gun switch and feed a bit wire until wire goes through feed rolls to gun. See
that wire is in grooves of both feed roll pairs!
• Press still the gun switch until wire has come through contact tip.
Automatic feed may sometimes fail with thin wires (Fe, Fc, Ss: 0,6 – 0,8 mm, Al: 0,8 – 1,0 mm).
Then it might be possible that you must open feed rolls and feed wire manually through feed
rolls.
