    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.
