Item Details

  • The Lincoln Electric K2902-1 is an advanced process add-on module designed for 3rd-generation Power Wave S and R series power sources. It enables specialized welding waveforms including Surface Tension Transfer (STT), Rapid X, and Low Fume Pulse by providing high-speed digital current regulation independent of wire feed speed.

Features

  • Surface Tension Transfer (STT) process control for independent current and wire feed speed regulation
  • ArcLink Digital Communications with integrated control cables for plug-and-play operation
  • Quick Lock Mounting System for secure attachment underneath the power source
  • Intelligent Protection against misconnection and voltage transients
  • Smart Fan Operation synchronized with the power source to reduce noise and energy consumption
  • High-speed digital current regulation for spatter reduction
  • Burnthrough control for thin materials and pipe root-pass welds
  • Included Power Source Output Pigtail Adapter Cable (Tweco-style)
  • Included Remote Voltage Sense Lead (25 ft)
