Pipemaster 516 – Power Source for Orbital Weldheads

The latest generation of Pipemaster controllers are the result of a new direction in power source design. The Pipemaster 516 brings the benefits of digital technology to the orbital welding customer: unparalleled accuracy, repeatability, and reliability. Digital technology forever eliminates the need for periodic weld head calibration – motor speeds and response characteristics remain accurate and stable regardless of wear, and weld heads can be interchanged without time-consuming calibration.


  • Multi-pass welding of pipes/tubes/tubesheets
  • Full function capability (torch rotation, filler wire feed, electronic arc gap control, electronic oscillation)
  • Operates all models of Magnatech weld heads(GTAW process)
  • Current programming and pulsing controlled by Pipemaster controller – not the power supply
  • Amperage output determined by power source selection
  • Autoranging power input eliminates all internal modifications
  • Up to 100 levels per program (time-based programs)
