Installation Of Welding Gun; Mounting And Locking Of Wire Reel; Automatic Wire Feed To Gun; Adjustment Of Pressure - Kemppi KEMPACT PULSE 2800 AUTOMOTIVE Manuel D'utilisation

2.6. INSTALLATION OF WELDING GUN

Make sure the gun wire conduit and the contact tip match the manufacturer's recommendations
for the type and diameter of wire you use. Too small a conduit may overload the wire feed device
and impede the wire feeding. Tighten the gun's quick connector to eliminate voltage loss. A loose
joint will heat up the gun and wire heater.
Never use defected gun.

2.7. MOUNTING AND LOCKING OF WIRE REEL

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.

2.8. 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 fi ller wire goes automatically to correct wire line.
– Make sure that groove of feed roll matches the diameter of welding wire used.
– 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 (fi le 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. 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: 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.
Note! Check that the wire or wire reel does not touch the equipment body, there is
a danger of short circuit!

2.9. ADJUSTMENT OF PRESSURE

Adjust the pressure of the feed rolls with the control screw so that the wire is fed into the wire
guide tube evenly and allows a little braking when emerging from the contact tip, without slipping
on the feed rolls.
Excessive pressure will cause the fi ller wire to fl atten and damage its coating, as well
as undue wear and tear of the feed rolls and friction damage.
