4. ASSEMBLY OF KEMPOWELD EQUIPMENT
Kempoweld power source: Read the paragraph INSTALLATION in the operation instructions for the power
source.
Wire feeder:
1. Mount the wire feeder unit into pin on the power source´s cover. When necessary you can lock the wire
feeder to the support piece on the power source´s cover.
2. Mount the control cable and welding current cable to connectors on the rear walls and the return current
cable to the connector on Kempoweld´s front panel.
3. Welding current polarity: By the connection made according to markings, the gun has positive voltage. In
order to change the polarity interchange the welding and return current cable ends connected to the power
source with each other.
4. If the MIG gun is water-cooled, mount the water hoses to the wire feeder unit.
5. Mount the interconnection cable to the same connections.
NOTE! The hoses of the water-cooled interconnection cable go also through the wire feeder unit.
6. The wire feeder must be mounted to boom without galvanic contact to lift hook and boom. See the paragraph
ACCESSORIES.
7. The MIG gun is mounted to the EURO connector. Use guide tubes and contact tips according to manufacturer´s
operation instructions. Accessories which are too narrow or otherwise unsuitable for the wire type used by
you, will cause disturbances and excessive wear for accessories.
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 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 screws 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.
9. The shielding gas hose is mounted to the rear wall of the wire feeder. Mountings to the gas bottle and the
shielding gas flow adjustment, see the paragraph Shielding gas.
KMW sync, see the paragraph ACCESSORIES.
8. Max. wire feed speed
When the unit is delivered the max. wire feed speed is 18 m/min, which is enough for most welding jobs.
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 in accessory drawer of the power
source.
