3.16 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 oc-
curs, 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.
3.17 Changing the Feed Roll
To change feed roll remove the feed roll retaining screw by turning in an anti-clockwise direction. Once the feed roll
is removed then to replace feed roll simply reverse these directions. Note: Be sure not to lose key that is located on
Drive Motor Shaft. This key must align with drive roll groove for proper operation.
A dual groove feed roller is supplied as standard. It can accommodate 0.6/0.8mm diameter hard wires. Select the
roller required with the chosen wire size marking facing outward.
