  • Page 12 Drive Roll Installation/Removal NOTE: Neither of the handles needs to be removed to access the Drive or Idler Rolls. 1. Pull the Cam Lever away from the idler roll. This will relieve the pressure against the drive roll (as shown in Figure 1). 2.

  • Page 13: Accessories

    Section C Accessories/Options Insulated Drive Roll Kits are used to prevent preheating of the wire which may soften it and clog the liner. This picking up of current at the drive rolls rather than at the contact tip is usually not a problem unless using too large of a contact tip or excessively oxidized aluminum wire.

  • Page 17: Troubleshooting

    Section E Troubleshooting Trouble No wire feed at torch, feeder not operating, i.e. no slave motor or brake solenoid. No wire feed at torch, feeder operating properly. Wire feeds, but welding wire is not energized. Wire feeds erratically. Wire feeds one speed only.

  • Page 18: Troubleshooting Guide

    Troubleshooting Guide Regardless of which torch or feeder used, all MK Products’ push-pull guns operate on the same principle. The slave motor in the feeder runs at a fast, constant speed, but has very low torque. It is always trying to feed more wire than the torch motor wants, and when the motor gets all it wants, it slows the slave motor, preventing a bird’s nest.
