    Miller® D-74D Dual Wire Feeder 300620 For .023" - 1/8" Carbon Steel Wire

    Do not worry about changing wire spools to alternate between two wires anymore. The Miller dual wire feeder allows you to change wires quickly and easily. The rotatable drive assembly allows for the rotation of the housing. Severe bends are reduced in the wire feed, prolonging the life of the gun liner and the gun itself. 

    Posifeed™ wire drive quickly surpasses wire feed competitors. Performance is enhanced by positive wire feeding. A calibrated drive roll-pressure arm provides quick and easy drive roll changes. Solid-state speed control removes the necessity for electrical relays and makes this machine more durable. All Miller guns will attach with quick connect. 

    This Miller wire feeder is equipped to handle MIG and Flux-Core welding. Equipped with a trigger hold, the D-74D allows welders in making longer welds. Arc starts are improved with automatic run-in control.
