Features

More Jobsite Productivity and Efficiency

  • ArcReach® capabilities eliminate the time spent tracing weld cables hundreds of feet back to the power source because operators can make adjustments directly at the wire feeder or remote.
  • Cable Length Compensation (CLC™) automatically adjusts output to account for voltage drop due to long weld cables, ensuring preferred weld parameters.
  • RMD® and pulsed MIG processes are fully supported, enabling faster and more efficient welding in the field.
  • Jobsite mobility is enhanced with one of the smallest and lightest machines in its class.
 

Built To Work Harder

  • Rugged construction with Wind Tunnel Technology™ protects internal components from dust and debris.
  • No control cords required – weld cables are used to communicate parameters, reducing maintenance costs.
  • Auto-Line™ allows operation on any input voltage (208–575 V, single- or three-phase) without manual linking.
  • Fan-On-Demand™ reduces noise, energy consumption, and contamination.
  • Universal connector system enables flexible configuration (Tweco®, Dinse, Cam-Lok).

Empower Your Welders

  • Remote control without a cord allows quick and easy adjustments at the wire feeder or remote.
  • Adjust While Welding (AWW™) enables parameter changes while the arc is active.
  • Automatic control lockout prevents unintended parameter changes at the power source.
  • Faster process switching restores previous settings when ArcReach accessories are removed.
  • Auto-Process Select™ automatically sets the correct weld process based on polarity.
  • Adaptive Hot Start™ improves arc ignition and reduces defects.
  • Infinite arc control allows fine-tuning for difficult materials and out-of-position welding.

ArcReach® Technology

ArcReach® technology uses existing weld cables to communicate control information between the feeder or remote and the power source. This eliminates the need for control cords, reducing costs, setup time, and potential failure points.
