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
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 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.
