OUTPUT, WIRE FEEDER AND
COMMUNICATION CONNECTIONS
(See Figure A. 2)
Connect a work lead of sufficient size and length (Per
Table A.1) between the Negative Output terminal on the
power source and the work. Be sure the connection to
the work makes tight metal-to-metal electrical contact.
To avoid interference problems with other equipment
and to achieve the best possible operation, route all
cables directly to the work and wire feeder. Avoid
excessive lengths and do not coil excess cable.
Minimum work and electrode cable sizes are as follows:
TABLE A.1
Current (60% Duty Cycle)
200A
300A
400A
500A
Note: The recommended cable size may need to
change depending on its quality. When the rated
current flow goes through, the total voltage drop on
ground cable and electrode cable must not exceed 4
volts.

WIRE FEEDER CONNECTION

(See Figure A. 2)
• Turn the INVERTEC TM
• Connect the K1785 control cable from the feeder to
the 14-pin connector.
• Connect the electrode cable to the Positive Output
terminal and to the feeder's electrode connection.
Refer to the wire feeder instruction manual for

For secure electrical connections, the hardware
connecting the output terminals and cables must
be tight. Damage to output studs and poor
performance may occur if this instruction is not
followed.
