The Miller® S-74D wire feeder comes with digital volt and wire feed speed (amp) meters and is capable of remote voltage control. It is a heavy industrial, four drive roll, 24 VAC wire feeder for MIG and flux-cored welding wires. The S-74D feeds .023 to 5/64 diameter welding wire at a wire feed speed range from 50 to 780 inches per minute. It comes standard with trigger hold, dual tension control, automatic run-in, and tool-less rotatable drive. Floating positive drive system provides smooth, trouble-free feeding of a variety of welding wires.

Features
Digital meters for easy viewing of the wire feed speed and voltage.
Remote voltage control allows operator to set voltage at the wire feeder without having to go back to the power source.
Tachometer feedback to help keep wire feed speed accurate.
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.
Floating positive drive system provides trouble-free feeding on a variety of wires.
