CEA Rainbow 150 V

RAINBOW's represent the latest evolution in inverter technology DC welding equipment.
These powerful 100 kHz power sources are based on latest generation IGBT’s and fitted with a flat transformer.
RAINBOW's, with their lightness, reduced size and their excellent characteristics in electrode(MMA) and TIG welding with "lift" mode arc striking, are the most suitable solution for maintenance and light fabrication works.
RAINBOW 153 cell and 183 cell VRD are special versions for cellulosic electrodes.
