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.
Superior exceptionally high welding characteristics with any type of electrode
Three available welding processes
Possibility to work with adequate size power generator sets.
Low energy consumption and high electrical efficiency
All the data are referred to 40° C environment temperature
Suitable to be used with 100 m length cable without power loss
Shock-proof fibre compound main structure with protected control panel
Dust-proof electronic components, thanks to the innovative “Tunnel” fan cooling system, allow its use in the toughest work environments
Sloping front control panel, easy to read and adjust and highly visible from any direction
Built-in Arc Force to automatically select the best welding arc dynamics
Automatic Hot Start to improve the arc striking with the most difficult electrodes
Electrode Antisticking function
RAINBOW 150 VRD and 183 CELL VRD, fitted with Voltage Reduction Device to make the maximum open circuit voltage less than 12 V, grants additional safety protection in all highly hazardous environments
