• Toolless rotatable drive assembly allows operator to rotate the drive housing, eliminating severe bends in the wire feed path which reduce gun liner life. Also aids in feeding difficult wires.
• Automatic run-in control significantly improves arc starts.
• Trigger receptacle oriented in a downward position to reduce potential damage.
• Trigger hold allows operator to make long welds without having to hold the trigger continuously. Reduces operator fatigue.
• Posifeed™ Wire Drive Assembly Features

  24 VDC high-torque, permanent-magnet motor.

  Quick-change drive rolls.

  Quick-release, calibrated drive-roll pressure adjustment arm allows drive roll change without losing spring preload setting.

  Four sealed ball bearing all-gear-driven drive-roll carriers for smooth, positive and accurate wire feed with long uninterrupted service life.

  Easy loading and threading of welding wire without having to release the drive-roll pressure arm.

  Solid-state speed control and brake circuit eliminates the need for electrical/ mechanical relays and increases service life.

• Uses Miller standard 1-5/8 in (41 mm) diameter drive rolls.
• Quick-connect for all Miller guns.
• Covered drive rolls – easy access, heavy-duty, molded composite cover over drive assembly.
