INPUT POWER SUPPLY CONNECTIONS
A qualified electrician should connect the input power
supply leads.
1. Follow all national and local electrical codes.
2. Use a three-phase line.
3. Remove the input access door at upper rear of the
machine.
4. Follow input supply connection diagram located
on the inside the door. For multiple voltage
machines, follow the diagram for the voltage that
is within 10% of your actual input line voltage.
5. Connect the three-phase AC power supply leads
L1, L2, and L3 to the input contactor
terminals in the input box assembly. See Figure
A.1.
RECONNECT PROCEDURE
Electric Shock Can Kill
• Disconnect input power before per-
forming this procedure.
------------------------------------------------------------------------
Multiple voltage machines are shipped connected to
the highest input voltage listed on the machine’s rating
plate. Before installing the machine, check that the
reconnect panel in the input box assembly is connect-
ed for the proper voltage.
Failure to follow these instructions can cause
immediate failure of components within the
machine. When powering welder from a generator
be sure to turn off welder first, before generator is
shut down in order to prevent damage to welder.
------------------------------------------------------------------------
To reconnect a multiple voltage machine to a different
voltage, remove input power and refer to the input
connection diagram located on the inside of case back
input access door. Follow the diagram for the voltage
that is within 10% of your actual input line voltage.
1. Figure A.2 shows a sample of the reconnect
instructions for a dual voltage machine.
