KWF 300/300S
LOCKED OPEN
– Release locking nails of wire reel hub by
turning locking knob a quarter round.
– Mount the reel at its place. Note rotating
direction of reel!
– Lock the reel with locking knob, locking
nails of hub remain to outside position and
will lock the reel.
Check that in filler wire reel there are no parts sticking out, which could e.g. chafe
against chassis or door of wire feed unit. Dragging parts might expose chassis of wire
feed unit under voltage.

2.5. AuTOmATIC WIRE FEEd TO guN

Automatic wire feed makes change of wire reel more rapid. In reel change the pressure of feed
rolls 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 roll
groove is selected by moving the groove selecting washer (28). N.B.! Also the selector plate
for 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 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.
WeldForce KWF wire feed units:
– Draw a bit of loose wire from wire reel. Feed wire through back liner to feed rolls. Do not
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). In
that case you might have to open feed rolls and feed wire manually through feed rolls.
