TIG DC welding inverter CEA RAINBOW 202 HF PRO

Single-phase TIG DC welding inverter CEA RAINBOW 202 HF PRO
Common Characteristics
Inverters from serie RAINBOW HF represent the latest evolution of inverter technology DC welding machines for professional applications. Equipped with a digital control, these powerful 100 kHz power sources, based on the very latest IGBT technology and fitted with flat transformer, can be used for TIG welding of any metal, excluding aluminium and its alloys. RAINBOW 202 HF PRO has also very well performing in MMA welding, due to their lightness and portability, are the ideal solution
for excellent quality welding in maintenance, assembly and light fabrication works.

Digital control of all the welding parameters.
TIG arc striking by high frequency or “lift arc.”
High performance on thin metal sheets.
Low energy consumption and high efficiency.
Energy Saving function to operate the power source cooling fan when necessary only.
Control panel protected against accidental impact.
Sloping front control panel, easy to read and adjust and highly visible from any direction.
Innovative “Tunnel” fan cooling system, allow their use in the toughest work environments.
Use of up/down TIG torches will enable to adjust directly from the torch the welding parameters.

“EASY PULSE” feature, in function of the chosen peak current, in a simple and automatic way will synergically generate an adequate pulse frequency (between 0.5 and 500 Hz) and a base current, both readjustable in a synergic way. Pulse parameter values preselected in the control will save setting time, by ensuring the best possible pulse parameter combinations, ideal for less skilled welders.
“CYCLE” function allows, by simply pressing the torch trigger, to continuously switch between two current values, previously preselected. This function is most
suitable for welding different thickness profiles, requiring a continuous current adjustment change.
VRD device reduces the open circuit voltage to values below 12 V, by enabling the use of the machine in highly hazardous environments for the operator’s maximum
