- IMPROPER USE 3.2 OTHER TECHNICAL DATA
It is dangerous to use the spot-welder for any other purpose than that for General specifications
which it is designed (spot resistance welding).
- (*)Power supply voltage and frequency : 400V(380V-415V) ~ 1ph-50/60 Hz
or 230V(220V-240V) ~ 1ph-50/60 Hz
- Enclosure protection rating: IP 22
PROTECTIONS
(*) The spot welder can be supplied with a 400V or 230V power supply; check the correct
value on the technical information plate
The safeguards and moveable parts of the spot-welder casing should all be in
position before connection to the power supply.
