- 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 Features24 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.
- Floating positive drive system provides trouble-free feeding on a variety of wires.
