You can change polarity of filler wire by interchanging the PROMIG welding current cable
and earth cable with welding cable connectors of PRO power source.
6. Max. wire feed speed
When the unit is delivered the max. wire feed speed is 18 m/min, 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 by replacing the gear wheel on motor shaft to a bigger one. The big gear wheel D40 is
delivered with the feed unit in accessory drawer.
When necessary speed is changed according to follo-
wing:
– Open side plate and move JUMPER BLOCK’s
10 th coding piece on control card A001 to
point 25 m/min.
– 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.
