Input Supply Connection
Only a qualified electrician can connect the welding
machine to the supply network. Installation had to be
made in accordance with the appropriate National
Electrical Code and local regulations.
Check the input voltage, phase and frequency supplied to
this machine before turning it on. Verify the connection of
ground wires from the machine to the input source. The
welding machine POWERTEC i250C STANDARD/
ADVANCED, POWERTEC i320C STANDARD/
ADVANCED must be connected to a correctly installed
plug-in socket with an earth pin.
Input voltage is 400 Vac 50/60Hz. For more information
about input supply refer to the technical specification
section of this manual and to the rating plate of the
machine.
Make sure that the amount of mains power available from
the input supply is adequate for normal operation of the
machine. The necessary delayed fuse or circuit breaker
and cable sizes are indicated in the technical
specification section of this manual.
The welding machine can be supplied from a power
generator of output power at least 30% larger than input
power of the welding machine.
When powering the machine from a generator be sure to
turn off welder first, before generator is shut down, in
order to prevent damage to welder!
