For all Lincoln CV power supplies except the R3S-325 the following applies. See section L-5 for the
R3S-325.
1. Connect the black and white contactor leads from the WC-1 or
Cobramatic to the terminal strip on the Lincoln power supply;
black to 2 & white to 4. Place WC-1 or Cobramatic in CLOSING
CONTACTS position (see Appendix for contactor information).
2. Plug the 115VAC plug from the WC-1 or Cobramatic into a
standard wall outlet or cut off the plug and wire black to 31, white
to 32 and green to ground lug.
3. Tape off WC-1 red and green leads and turn off Posa Start switch
as Posa Start is not used.
Note: Some Lincoln gas drives use slightly different numbering on the terminal strip. However, 2 & 4
are still the contactor and 31 & 32 are still the 115VAC. If using a gas drive in CC mode red and
green Posa Start leads must be connected. (see section L-8, 9 ).
L-5
For the Lincoln R3S-325 the following applies.
1. Connect the black and white contactor leads extending from the
WC-1 or Cobramatic to the terminal strip on the R3S-325; black
to 32 & white to 4. Place the unit in CLOSING CONTACTS
position (see Appendix for contactor information).
2. Plug the 115VAC plug extending from the WC-1 or Cobramatic
into a standard wall outlet or cut off the plug and wire black to
32, white to 31 and green to ground lug.
3. Tape off WC-1 red and green leads and turn off Posa Start

L-6
The PA-L1 Control (P/N 005-0676) comes equipped with a 14 Pin (X-clocked) amphenol connector and
simply plugs into any Lincoln CV-type welder that has a 14 Pin (X) socket. This unit operates on 42
volts and is for "CV" only. If the welder has a remote voltage control, it should be set on "Panel". The
contactor switch should be on "Remote". Most of the newer Lincoln shop machines now use a dinse
style connector (MK P/N 153-0755) which would have to replace the lug on the power cable of the
Prince XL spool gun.
New Lincoln power supplies use a 14-Pin (X clocked) amphenol similar to the Miller machines, however,
the pins are clocked differently than the Miller (S clocked) amphenol.
1. Connect the black and white contactor leads from the WC-1 or
Cobramatic to the 14-Pin amphenol; black to d & white to pin C.
Place unit in CLOSING CONTACTS position (see Appendix for
contactor information).
2. Plug the 115VAC plug from the WC-1 or Cobramatic into a
standard wall outlet or cut off the plug and wire black to J, white
to a and green to pin B.
3. Tape off WC-1 red and green leads and turn off Posa Start
switch as Posa Start is not used.
Note:
If unit does not have a 14-Pin see section L-4 .
