Setting The Spool Brake Force; Loading The Welding Wire To Feed Mechanism - Kemppi Kempact 251R Operating Manual

Setting the spool brake force

To prevent the filler wire from uncoiling on overrun following use at high feed speeds, you can
change the brake force of the welding spool. Adjust the spool brake force through the hole in
the spool locking mechanism. Increase the force by turning the screw clockwise and decrease
it by turning it anticlockwise.
Do not over tighten and reduce the pressure for light filler wire types.

roll groove and through the wire guide(s) tubes and Euro connector block, exposing
about 150 mm of filler wire from the front of the machine.
3. Close the top feed roll(s) lever(s) over the filler wire and close the pressure arm(s).
