able. All our machinery and systems are
subject to continual development. We
must therefore reserve the right to mod-
ify their construction and properties.
Description
RAINBOW 200 HF
with digital control
represents the very latest evolution in
direct current weld generators with
INVERTER
technology. This powerful
100 KHz generator, based on the latest
generation IGBT, fitted with a planar
transformer, makes it possible to TIG
weld any metal except for aluminium
and its alloys.
RAINBOW 200 HF
, also excellent for
electrode welding, with its lightness and
compactness and first-rate welding
characteristics, is ideal for using for
maintenance, erection and light steel
structural works.
Main features are:
• Precise and efficient TIG arc striking
by high frequency
• High performance on thin metal
sheets
• Standard equipped with pulse mode
integrated into the control with avail-
able
EASY PULSE
facility
• Digital control of all the welding
parameters with the possibility of stor-
ing 9 personalised programs
• Automatic compensation for mains
voltage within +15% -20%
• Low energy consumption and high
efficiency
• Innovative and compact design
• Shock-proof plastic main structure
