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

Comparison of State of Arc - Conventiocal CV and REGARC™ process

Structural Beam Welding Robot System

Applicable for wide range of welding points with specialized positioner and turn welding function
Simple operation with specialized software for teaching
FAMILIARC™ MX-Z200MP enables low spatter welding and beautiful bead shape
