3.2 installatiOn OF the wire Feed system
wire feeder unit:
1. Mount the return current cable to connector on the Kempomat´s front panel.
2. The MIG gun is mounted to the EURO connector of the wire feeder unit. Use guide tubes
and contact tips according to manufacturer´s operation instructions. Accessories which
are too tight or otherwise unsuitable for the wire type used by you, will cause wire feed
disturbances.
3. Max. wire feed speed
When the unit is delivered the max. wire feed speed is 18 m/min, which is enough for the most
welding works. If you need a higher speed, you can increase the max. wire feed speed to 25 m/
min by replacing the gear wheel on motor shaft to a bigger one. The big gear wheel (D40) is
delivered on order.
when necessary speed is changed according to following:
• Open tightening lever (20). Remove lower feed rolls (21). Release screw (23) and its
washer. Remove gear wheel D28 (24) from motor shaft.
• Loosen screws (25) (3 pc) 1 twist. Mount the D40 gear wheel onto motor shaft. Screw the
screw (23) with its washer back.
• Put feed rolls (21) back to their axles, however don´t fasten yet fastening screws of the
feed rolls (22).
• Lift the motor so that the tooth gap between gear wheel and both lower feed rolls is
approx. 0,2 mm.
• Tighten screws (25). Check gear teeth gaps, when necessary put the motor into a better
position. Screw on the mounting rolls of feed rolls (22).
• Too small gap between gear wheel and feed rolls will overload motor.
• Too big gap for its part might cause too rapid wearing for teeth of feed rolls and gear
wheel.
4. The shielding gas hose is mounted to the snap connector on the rear wall of the
unit. Mounting to the gas bottle and shielding gas flow regulation, see paragraph for
