Best In-Class Productivity

Productivity. Boosted.
Downtime. Reduced.
Rework. Cut.

Auto-Line™ Power Management

Automatically compensates for various input Voltage. Suits jobsite and generator power. Keeps welding output constant even if input power varies by ±10%. Single or 3 phase.

Easy To Use

  • The PipeWorx 350 FieldPro™ is streamlined and simplified to reduce setup time and potential weld defects. Push button process changeover eliminates the need for swapping cables.
  • The robust design will withstand harsh environments common in the field.

Complete Remote Control

  • The FieldPro™ Remote provides all the same functionality of the PipeWorx 350 FieldPro™ hundreds of feet from the power source, including process changeover, and Amperage adjustment with no special cables.
  • Connect the FieldPro™ Remote in line with the electrode holder or TIG torch with standard welding cables and have complete remote control.

Superior Arc Perfomance

  • The optimized Stick and TIG performance specifically meets the needs of open root pipe welding and helps reduce training time and increases quality
  • Starts maintain root opening and prepared edge and stops limit arc marks outside of the heat-affected zone.


Complete Control At the Weld Joint

  • FieldPro™ Remote reduces weld defects by automatically setting correct polarity for each welding process — without the need to manually swap cables.
  • Eliminates the need to “get by” with less than optimal settings without control cables, and allows for easy setup of a new weld process with the touch of a button.
  • Total remote control of welding processes and parameters improves safety by limiting jobsite movement and reducing slip, trip and fall hazards.

Simplified Cable Management

  • Save time by eliminating the need to trace cables back to change welding parameters and processes.
  • No control cables to string and manage on the jobsite.

Arc Performance Optimised for Critical Pipe Welding

  • Industry-leading arc performance like the PipeWorx 400 Welding System, but in a field-ready package.
  • True multi-process system provides conventional Stick, TIG, FCAW, and MIG welding as well as the advanced technologies of RMD and Pulse.
  • Smart Feeder delivers excellent RMD and Pulse welding up to 60 metres away from the power source with no control cables.
  • RMD and Pulse processes also help reduce weld failures and eliminate backing gas on some stainless and chromoly applications.
