4.07 Feed Roll Pressure Adjustment
The pressure (top) roll applies pressure to the grooved feed roll via an adjustable pressure knob. 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 knob clockwise.
WARNING
Before changing the feed roll 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 rolls, shafts and bearing.
4.08 Changing the Feed Roll

to replace feed roll simply reverse these directions.
NOTE!

proper operation.
A dual groove feed roll is supplied as standard. It can accommodate 0.6/0.8mm diameter hard wires. Select the roll required with the
