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.
