Item Details

  • The Lincoln Electric K940-25 STT® Sense Lead Kit is a 25-foot (7.6 m) voltage sensing cable designed to provide real-time arc voltage feedback directly from the workpiece to the power source. This accessory bypasses voltage drops inherent in standard welding cables, allowing the power source to monitor voltage at the arc rather than at the output studs. This feedback loop is required for advanced waveforms like Surface Tension Transfer (STT), enabling millisecond-level adjustments to current and voltage based on the real-time state of the weld puddle.

Features

  • Real-time arc voltage feedback for precise waveform control
  • Eliminates voltage drop variables from long welding cables
  • Enables millisecond-level adjustments to current and voltage
  • Monitors voltage at the arc rather than output studs
  • Spatter reduction
  • Arc stability enhancement
  • Consistent penetration control
  • Durable industrial-grade insulation
  • OEM connection hardware included
