Miller PipeWorx 400 #907384

Multiprocess pipe welding system designed exclusively for pipe fab shops. The PipeWorx system delivers more arc-on time, fewer weld defects or rework, superior weld quality and less training. Configure a custom PipeWorx System -- Select a power source, wire feeder and cable package for a complete system.

What's Included:

  • Short gas hose for connecting output gas connection on power source to TIG block.

Not Included:

  • Power Cord


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 multiple 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. PipeWorx "Quick-Select" technology automatically selects the welding process, the correct polarity, cable outputs and welding parameter.
  • Quick process changeover eliminates set-up time for switching 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 your unique return on investment an payback based on your shop and utilizing the savings that PipeWorx Welding System delivers.
