JUMPER BLOCK
7 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 in accessory drawer of the Promig 501, 501L and 530 and in the
Promig 100 it is in plastic bag under cover.
When necessary speed is changed according to following:
1. Open cover of control box of the Promig 501, 501L and 530 and move
JUMPER BLOCK’s WFS jumper on control card A001 to point 25 m/min.
2. Change the gear wheel in both feeder units as follows:
- 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
gearwheel.
