5.04 Feed Roll Pressure Adjustment
The pressure (top) roller applies pressure to the grooved feed roll 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.
A simple check for the correct drive tension is to bend the end over of the wire (once out the end of the MIG
Gun) and hold it about 50mm from a piece of wood (an insulated object) and let it run into the wood. The
wire should coil up without stopping and slipping at the drive rollers, tighten the pressure/tension adjustment
screw if it slips.

WARNING
Keep hands clear of the contact tip holder while feeding wire through to the gun. The wire can easily pierce you skin
resulting in injury.
Keep MIG Gun away from eyes and face.
!!
WARNING
Before changing the feed roll ensure that the mains 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.
5.05 Changing the Feed Roll
To change the feed roll, release the Wire Drive Tension Screw and lift upward. Move the Pressure Roller Arm
(top roller) out of the way. Remove the feed roll retaining cover by rotating it anti-clockwise 90 degrees and
lifting upwards. The feed roll can now be changed. Once the feed roll is removed then replace the feed roll,
ensuring you have the correct groove size matching the wire size you are using in the welder. Re-install by
following these instructions in reverse.

WARNING
Moving Parts can cause injury!
