4.06 Feed Roller Pressure Adjustment

The pressure (top) roller applies pressure to the grooved feed roller via an adjustable pressure screw. These devices should be ad-
justed to a minimum pressure that will provide satisfactory wire feed 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 debris. 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.
