Miller Pipeworx 400 Welding System

Simplified and optimized for pipe fabrication shop welding, the PipeWorx systems streaming set-up with one touch welding, quick process changeover, and Pulsed and Modified Short-Arc MIG processes, makes training and turn-around times faster than ever before.


  • What's Included:
    • PipeWorx 400 Power Source, 230/460V
    • PipeWorx Dual Feeder with drive rolls (300366)
    • Two 15-ft (4.6 m) PipeWorx 300 A MIG Guns (195400)
    • Side-mount Cable Hangers
    • Cable Kit with 25-ft (7.6 m) Work Sense Lead (300367)
    • Running Gear with Dual Cylinder Rack (300368)
  • Simple Process Setup:
    • Clearly labeled controls in easy-to-understand welder terminology.
    • Requires just a few basic steps to set up a new weld process, resulting in less training time and minimizing errors from incorrect setups.
    • The front panel was designed by welders for welders. Only backlit controls are adjustable to eliminate confusion.
    • Memory feature stores four programs for each selection: Stick, DC TIG, and MIG (left and right side of feeder). Beneficial when using mulitple procedures, multiple process parameters or multiple welders and eliminates the need to remember parameters.
  • Quick Process Changeover:
    • No need to manually switch polarity or cables and hoses between processes. Simply push a process selection button to choose a welding process. PipWorx 'Quick-Select' technology automatically selects the welding process, the correct polarity, cable outputs and welding parameter.
    • Quick process changeover eliminates set-up time for switvhing cables and gas hoses. Also, reduces the risk of weld reworks due to incorrect cable connection.
  • Multiprocess Machine:
    • Weld processes are optimized to deliver superior arc performance and stability specifically for root pass, fill and cap pipe welding.
    • Includes conventional Stick, DC TIG (Lift-Arc or HF Start), Flux-Cored and MIG welding processes.
    • Also features the advanced RMD and Pulsed MIG processes that deliver superior quality welds, increase productivity, and reduce rework and training.
  • Streamlined System:
    • Wind Tunnel Technology and Fan-On-Demand provide system protection in the dusty shop environment.
    • Innovative cable and gun storage manages clutter for a cleaner, organized weld-cell area.
    • Cables remain connected to the power source and do not need to be switched for the different welding processes.
    • All system components have been selected to meet the needs of a pipe fabrication shop.
  • PipeWorx ROI Calculator: The PipeWorx ROI calculators are designed to help you determine you r unique return on investment and payback based on your shop and utlizing the savings the PipeWorx Welding System delivers.
  • Not Included:
    • PipeWorx Accessories Kit for Dual Feeder, 300568 (25-ft work cable, EG500 work clamp, two Miller Smith flowmeter regulators and two 4-ft gas hoses)
    • Power Cord
    • Filler Metals
    • Shielding Gas
