OUTPUT CONNECTIONS

ELECTRODE AND WORK CABLES

Use the shortest possible cable lengths. See Table A.1
for recommended cable sizes based on length.

The output terminals are located at the lower front of
the welder behind a hinged door. Refer to Figure A.3.
Route the welding cables through the slotted strain
reliefs of the base to the welding terminals.

LOW INDUCTANCE TERMINAL

On the DC-655, the inside right Negative (-) output ter-
minal is lower choke inductance. This terminal is
presently only recommended for CV mode welding
with NR203Ni 1% negative polarity procedures.. All
other processes are to be welded using the outside
right Negative (-) output terminal with higher choke
inductance. CC mode processes must use high
inductance.

For Positive Polarity:

1. Connect the work cable to the high inductance (-)

terminal (marked " ").

2. Connect the electrode cable to the positive terminal

marked “+”.

3. Remove the terminal strip access cover panel on

the lower case front. Refer to Figure A.3 for the
location.

4. Work Sense lead #21 from the 14 Pin MS-recepta-

cle must be connected to “-21”on the terminal strip.
Note: This is how the DC-655 is shipped from the
factory.

5. Replace the terminal strip access cover panel.

For Negative Polarity:

1. Connect the electrode cable to the appropriate high
