2. DESCRIPTION
400, 600 and 850 models are MMA (coated electrode) and TIG (with torch with valve) welding rectifiers. 600 and
850 models allow ARC-AIR gouging and cutting. Current adjustment is tiristorized and effectuated locally or remotely at
distance.
They allow welding of all kinds of electrodes (400 model until 6 mm diameter and 600 and 850 models until 8 mm
diameter) and TIG (for mild steels, stainless steels, copper and brass).
All models are equipped with a 230V 2200V
single-phased socket, located on the rear
panel, for electric tools, econoTIG and high
frequency generator for TIG welding
connection.
Attention: do not plug or use any electric
tool during welding procedure.
