5.3. MOUNTING AND LOCKING WIRE REEL
– Release locking nails of wire reel hub by turning locking knob
to the position OPEN.
– Put the reel at its place. Note the rotating direction of reel!
– Turn locking knob to the position LOCKED.
Check filler wire reel for no protruding parts, which could e.g. chaff against chassis or wire feed unit
door. Dragging parts could expose chassis of wire feed unit under voltage.
5.4. AUTOMATIC WIRE FEED TO GUN
Automatic wire feed makes the change of wire reel quicker. The pressure on feed rolls need not be released and
filler wire goes automatically to correct wire line.
– Make sure that the groove of feed roll matches the diameter of
welding wire used. Feed roll groove is selected by moving the
groove selection washer. 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 the reel and cut off the bent length.
Be careful that the wire does not spill from the reel to the sides!

– Straighten approximately 20 cm of the wire. Ensure that the wire end has no sharp edges, if necessary file
them off. A sharp edge may damage the wire guide tube and contact tip of welding gun.
– Draw a piece of loose wire from wire reel. Feed wire through back liner to feed rolls. Do not release the
pressure of the feed rolls!
– Press the gun switch or wire inch switch and feed a piece of wire through feed rolls to the gun. Ensure that
wire is in the grooves of both feed rolls!
– Hold down the switch until the wire has come through the contact tip.
Automatic feed may sometimes fail with thin wires (Fe, Ss: 0,6...0,8 mm, Al, Fc: 0,8...1,0 mm). In this case,
open feed rolls and feed the wire through manually.
5.5. ADJUSTING PRESSURE
Adjust the pressure of feed rolls with control screw, so that the wire is fed into the wire guide tube evenly, and
allows a little braking when coming out from the contact tip, without slipping on the feed rolls.
Excessive pressure causes flattening of the filler wire and damage to the coating. It also causes friction
and undue wear of the feed rolls.
5.6. ADJUSTING THE TIGHTNESS OF WIRE REEL BRAKE
Brake force is adjusted through a hole in the locking device
of reel hub by tightening/loosening the adjustment screw with
a screwdriver.
Adjust the brake force so big that the wire does not slip from
the full reel when the reel stops rotating. The need for brake
force is increased with wire feed speed.
Standard accessory: 200 mm wire reel adaptor
Make sure that the welding gun is designed for the maximum welding current! Do not use a damaged
welding gun!
5.7. RETURN CURRENT CABLE
Fasten earth clamp of return current cable carefully, preferably direct to welding piece. Contact surface of the clamp
should always be as large as possible.
Clean the fastening surface from paint and rust!
Use copper cables in your Kempoweld equipment. A too small cross-sectional area might cause overheating of
connectors and insulations.
