Caddy TIG HF is provided with a thermal cut-out to prevent overheating of the welding
power source. In the event of overload the supply voltage is interrupted, the yellow led on
the front goes on and an error code starts blinking on the display accordingly to the follow:
E01 = overtemperature
E03 = overload with respect to allowed duty cycle
In case of error E01 or E03 resetting takes place automatically as soon as the welding
power source has cooled down.
Error code E20 could also be displayed; in that case switch off and on again the machi-
ne: if E20 is still displayed, call Service.

Caddy TIG HF both has mains voltage compensation, which means that + 15% fluc-
tuation in the supply voltage produces a negligible variation in the welding voltage.

In order to reduce noise, no load consumption and metallic powder movement, Caddy
TIG HF has a special device that control the fan velocity; the higher is the internal tem-
perature the faster is the fun speed.
