4.07 Feed Roller Pressure Adjustment

The pressure (top) roller applies pressure to the grooved feed roller via an adjustable pressure screw. These devices should be

adjusted to a minimum pressure that will provide satisfactory WIREFEED without slippage. If slipping occurs, and inspection of the

wire contact tip reveals no wear, distortion or burn back jam, the conduit liner should be checked for kinks and clogging by metal

flakes and swarf. If it is not the cause of slipping, the feed roll pressure can be increased by rotating the pressure screw clockwise.

WARNING

Before changing the feed roller ensure that the Electricity Supply to the Power Source is switched off.

CAUTION

The use of excessive pressure may cause rapid wear of the feed rollers, shafts and bearing.

To change feed roll remove the feed roll retaining screw by turning in an counterclockwise direction. Once the feed roll is removed

then to replace feed roll simply reverse these directions.

A dual groove feed roller is supplied as standard. It can accommodate 023"(0.6mm) -.030" (0.8mm) diameter hard wires. Select

the roller required with the chosen wire size marking facing outward.
