Product Information

Product Literature (PDF)

SubArc Interface Analog.
A basic, easy-to-understand control box with all needed features. Start and crater parameters are individually adjustable. Only for use with DC Digital power sources.

SubArc Interface Digital.
A full feature control box with Digital read out and memory functions for 15 work points / programs. Start and crater parameters are individual adjustable. CV+C mode allows operator to preset voltage and amperage rather than wire feed speed. Adjustable AC Balance or welding polarity, standard set for two DC modes and 12 best-practice AC balance settings. Suitable for DC as well as AC/DC sources.

Internal terminal strip is able to integrate with positioners, side beams, turning rolls and other peripheral equipment.
