Adjusting 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 weak, the roll will slide on the
wire. If the roll pressure is set too heavy the wire may be
deformed, which cause feeding problems in the welding.
The pressure force should be set properly. For this
purpose 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.
