7.3.1 Wire spool brake
The wire-holding arbor (F) is equipped with a spool brake to prevent the wire spool (G) from continuing to
run when the wire feeder motor stops. The braking effect can be increased by turning the hexagon socket
screw (E) clockwise.

Description
2-cycle operation: for short weld seams and tack welding. The welding process
continues as long as the torch trigger is pressed.
4-cycle operation: for long weld seams. The welding process starts when the
torch trigger is initially pressed and stops when the torch trigger is pressed
again.
Spots: when spot welding is selected, two overlapping sheets of metal can be
pressed together and are welded through at various contact points known as
"spots". To achieve flat weld spots, the correct appropriate intensity must be
selected in accordance with the sheet thickness. The welding process begins
when the torch trigger is pressed and ends at the spot time set using the control
dial (D). The next welding process begins when the torch trigger is pressed
again. If the torch trigger is released prematurely, the welding process is
immediately stopped.

Unscrew the knurled screw (C).
Ensure that the groove in the wire feed roller is aligned with the wire guide tube (B).
Ensure that the wire feed roller is installed in the correct position. Insert the wire feed roller in such a way
that the required size (e.g. 0.8) can be read from the front.
Use the spring pressure unit (A) to set the contact pressure of the wire feed roller so that the wire is fed
uniformly and does not buckle when the cable assembly is extended.
