"R(N)"series-specially designed for REGARC™ Process / compatible with conventional constant voltage welding)

Welding Robot System

REGARC™ Process

  • Achieves systenatic and smooth droplet transfer for global transfer through our original current / voltage wave form controller, and reduce production time with lower spatter generation
  • REGARC™ Process can be equipped on Comact, Large assembly (2-arc), Core connection (2-Arc), Multi-work welding robot sysytem.

REGARC™ greatly reduces the amount of spatter adhensive to Torch Nozzle and Work

Minimize spatter adhered to shield nozzle and work piece

  • Low spatter generation
  • Low hume generation
  • High deposition efficiency
  • Deep penetration
