Item Details

  • The Lincoln Electric Power Wave Advanced Process Module (K3685-1) is an industrial-grade inverter/chopper peripheral designed to expand the capabilities of 3rd generation Power Wave S-Series and R-Series power sources. It provides alternating current (AC) welding, high-frequency (HF) TIG, and advanced waveform control for specialized processes including STT and Rapid X. The module integrates directly with the power source via a Quick Lock mounting system and ArcLink digital communications.

Features

  • Enhanced Process Capabilities: Provides automatic multi-process polarity switching and access to AC, STT, Rapid X, and Low Fume Pulse processes.
  • High Frequency TIG: Features a dedicated Twist-Mate connection for High Frequency GTAW applications.
  • ArcLink Digital Communications: Integrated control cables allow for plug-and-play operation and high-speed synchronized switching commands.
  • Quick Lock Mounting System: Secures the module directly underneath the power source to minimize equipment footprint.
  • IP23 Safety Rating: Protects against foreign bodies greater than 12mm and water spray up to 60 degrees from vertical for outdoor use.
  • Intelligent Protection: Prevents damage from misconnection and voltage transients.
  • Smart Fan Operation: Synchronizes with the host power source to minimize noise and energy consumption.
  • Sync Tandem Support: Includes differential input and output for automated Sync Tandem applications.
  • Package Components: Includes Power Source Output Pigtail Adapter Cable (Tweco-style), 25 ft (7.6 m) Remote Voltage Sense Lead, ArcLink Output Receptacle, and Shielding Gas Input.
