What's Included

  • PipeWorx 400 Power Source, 230/460V
  • PipeWorx Dual Feeder with drive rolls (300366)
  • Two 15 ft (4.6 m) PipeWorx 300A MIG Guns (195400)
  • Side-mount Cable Hangers
  • Cable Kit with 25ft. (7.6m) 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 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.
