RAINBOW HF

Arc welding

RAINBOW HF

OUR ICON FOR PRECISION DC TIG WELDING

SINGLE PHASE TIG DC INVERTER WELDING EQUIPMENT

RAINBOW HF is the iconic welding machine that has introduced the innovative inverter technology for professional TG DC welding machines in a curved design.
Equipped with a digital control, these powerful 100 kHz power sources, based on IGBT technology and fitted with flat transformer, can be used for TIG welding of any metal, excluding aluminium and its alloys.

RAINBOW HF

Ultra-compact, light and powerful

RAINBOW HF 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.

Other characteristics

Digital control of all the welding parameters
TIG arc striking by high frequency or “lift arc”
High performance on thin metal sheets
Energy Saving function to operate the power source cooling fan only when necessary
Sloping front control panel, easy to read and adjust and highly visible from any direction
Thanks to the “Tunnel” fan cooling system, IP 23 protection class and dust-proof electronic components 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

Technical features

PULSE MODE RAINBOW

SYN PULSE

SYN PULSE will synergically generate pulse frequency and base current

FAST PULSE

Adjust frequency from 0,5 Hz to 500 Hz

SLOW PULSE

Adjust separately current/time of peak and base

(RAINBOW 182 HF pro – 202 HF pro)
