1. Open the locking lever (1) and remove the lower feed rolls (2). Open the screw (4) and
remove its washer. Then remove the gear wheel (5) from motor shaft.
2. Loosen the screws (6) by one turn and replace the gear wheel with the larger one.
Tighten the screw (4).
3. Put the lower feed rolls (2) back to their place, but don't tighten the screws.
4. Lift the motor so that there is a clearance of about 0.2 mm between the gear wheel and
the lower feed rolls.
5. Tighten screws (6). Check the gear clearance and adjust the motor position if necessary.
Tighten the feed roll srews (3).
to set the jumper setting, do the following:
1. Turn the feeder off.
2. Remove the plastic cover of the feeder by unscrewing the fixing bolts.
3. Locate the control card inside the feeder and change the position of the jumper X6 so
that it connects the two pins.
4. Replace the cover of the feeder and tighten the fixing screws.
3.2 Adjusting the pressure OF the Feed rOlls
1
The pressure adjustment knob is located at the end of the locking lever (1). With the
adjustment knob you can adjust the pressure of the feed rolls, so that the wire runs smoothly
into the wire liner and brakes a little when coming out of the contact tip.
Make sure that the pressure is hard enough to avoid wire from slipping in the feed rolls, but
not too hard, because then it might flatten the welding wire or damage its coating. Too hard
pressure may also cause friction and excessive wearing of the feed rolls.
3.3 Adjusting the spOOl BrAke
The Kemppi ArcFeed is equipped with a spool brake to prevent the wire from unwinding and
tangling when the spool stops rotating at the end of the weld. The need for spool brake force
is increased with the increase of the wire feed speed.
The spool brake causes extra load to the wire feed motor, so do not apply too high brake force.
to adjust the spool brake in model 200, do the following:
A
B
Increase the spool brake force by turning the brake adjusting knob (B) clockwise. To decrease
the brake force, turn the knob anticlockwise.
