and return current cable with the Kemppi WeldForce power source welding cable connector.
4. Max. wire feed speed
When the unit is delivered the max. wire feed speed is 18 m/min (709 ipm), which is enough for
most welding works. If you need a higher speed, you can increase the max. wire feed speed to
25 m/min (984 ipm) by replacing the gear wheel on motor shaft to a bigger one. The big gear wheel

– 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, do not fasten the fastening screws of feed
rolls yet (22).
– Lift the motor so that the tooth gap between gear wheel and both lower feed rolls is approx.
0.2 mm (.008").
– 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).
If the gap is too small between gear wheel and feed rolls it will overload the motor.
If gap is too big for its part might cause too rapid wearing for teeth of feed rolls and
gear wheel.
