Dragging parts might expose chassis of wirefeed unit under voltage.2.5. AUTOMATIC WIRE FEED TO GUNAutomatic wire feed makes change of wire reel more rapid. In reel change the pressure of feedrolls need not to be released and filler wire goes automatically to correct wire line.– Make sure that groove of feed roll matches the diameter of welding wire used. Feed rollgroove is selected by moving the groove selecting washer (28). N.B.! Also the selector platefor changing the feed roll groove has to be moved similarly.– Release the wire end from reel and cut off the bent length. Be careful that the wire does notspill from the reel to sides!– Straighten about 20 cm (8 in) of the wire and see that the end of it has no sharp edges (file offif necessary). A sharp edge may damage the wire guide tube and contact tip of the weldinggun.WeldForce KWF wire feed units:– Draw a bit of loose wire from wire reel. Feed wire through back liner to feed rolls. Do notrelease pressure of feed rolls!– Press the gun switch and feed a bit wire until wire goes through feed rolls to gun. See thatwire 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 (.025....030”),Al: 0.8...1.0 mm (.030....040”). In that case you might have to open feed rolls and feed wiremanually through feed rolls.Moving the groove selecting washer Moving the selectore plate2.4.
