RECONNECT 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 con-
nected 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 the welder
------------------------------
To reconnect a multiple voltage machine to a different
voltage, remove input power and change the position
of the reconnect board on the Reconnect Panel.
Follow The Input Connection Diagram located on the
inside of Case Back Input Access Door.
These connection diagrams for the following codes are
listed below.

1. TURN OFF THE INPUT POWER USING THE DISCONNECT SWITCH AT THE FUSE BOX
2. DISCONNECT AND INSULATE THE H2 LEAD TERMINAL WITH TAPE TO PROVIDE AT
LEAST 600 VOLT INSULATION.
3. CONNECT L1, L2 & L3 INPUT SUPPLY LINES H1 AND H3 TRANSFORMER LEADS TO THE INPUT SIDE OF
THE CRI CONTACTOR AS SHOWN.
4. CONNECT TERMINAL MARKED TO GROUND PER LOCAL AND NATIONAL ELECTRIC CODES.
5. MOUNT THE LINKS IN THE POSITIONS SHOWN WITH THE PROVIDED HEX NUTS,
DOUBLE UP THE LINKS IN TWO OF THE POSITIONS TO SAVE THEM FOR FUTURE USE. SECURE THE
REMAINING HEX NUTS IN PLACE.
