Tandem Arc Welding System

Features

  • Tandem welding reduces the cycle time by about 40% compared to single welding.
  • Advanced Lord Characteristic Control and Synchronous Amplitude Modulation Control function ensures stable arc and lower spatter welding.
  • Dual Arc Sensor detects the difference in the amperage of the leading and the trailing wire and adjusts the alightment of the leading wire as well as correct the misalignment of the trailing wire during welding. This function significantly improves the welding quality and reduces the need for repair welding.
