Adjusting of Force of Pressure Roll
Force
The pressure arm controls the amount of force the drive
rolls exert on the wire.
Pressure force is adjusted by turning the adjustment nut
clockwise to increase force, counterclockwise to decrease
force. Proper adjustment of pressure arm gives the best
welding performance.
WARNING
If the roll pressure is too low the roll will slide on the wire.
If the roll pressure is set too high the wire may be
deformed, which will cause feeding problems in the
welding gun. The pressure force should be set properly.
Decrease the pressure force slowly until the wire just
begins to slide on the drive roll and then increase the
force slightly by turning of the adjustment nut by one turn.

out flat.
Insert the wire through the guide tube, over the roller
and through the guide tube of Euro Socket into liner of
gun. The wire can be pushed into the liner manually
for a few centimetres, and should feed easily and
without any force.
WARNING
If force is required it is likely that the wire has missed the
liner of gun.
Turn the input power ON.
Depress the gun trigger to feed the wire through the
gun liner until the wire comes out of the threaded end.
When trigger is released spool of wire should not
unwind.
Adjust wire spool brake accordingly.
Turn the welding machine off.
