RECONNECT PROCEDURE
Multiple voltage machines are shipped connected to
the highest input voltage listed on the machineʼs rating
plate. Before installing the machine, check that the
Reconnect Panel in the Input Box Assembly is con-
nected for the proper voltage.
CAUTION
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 the welder.
