Hidden Tig Functions - ESAB Caddy A32 Instruction Manual

3 TIG WELDING
Voltage Reducing Device (VRD)
The VRD function ensures that the open-circuit voltage does not exceed 35 V
when welding is not being carried out. This is indicated by a lit VRD LED.
The VRD function is blocked when the system senses that welding has started.
If the VRD function is activated and the open-circuit voltage exceeds the 35 V
limit, this is indicated by an error message (16) appearing in the display and
welding cannot be started whilst the error message is displayed.
Contact an authorised ESAB service technician to activate the function.
