  • Bernard PipeWorx 300 Amp Gun (195400) Learn More
  • Power cord
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.
Complete Control at the Weld Joint
  • 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.
Arc Performance Optimized for Critical Pipe Welding
  • Industry-leading arc performance like the PipeWorx 400 Welding System, but in a field-ready package.
  • True multiprocess 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 Pulsed MIG Welding
  • Up to 200 feet away from the power source with no control cables - twice the distance previously possible. RMD and Pulsed MIG processes also help reduce weld failures and eliminate backing gas on some stainless and chromoly applications.
Durable Design Reduces Downtime
  • Impact-resistant feeder case and the elimination of control cables provide a solid solution to last in harsh environments.
Synergic Processes
  • RMD and Pulsed MIG welding permits procedures with one wire and one gas to eliminate process switch-over time.
Easy Process Changeover
  • Simply connect the FieldPro Smart Feeder to your leads and you are ready to go. All controls automatically shift to the FieldPro Smart Feeder.
