The WC-1 Weld Control or the Cobramatic Cabinet can also be connected to Miller CV power supplies
with a 14-Pin amphenol as follows:
1. Connect the black and white contactor leads from
the WC-1 or Cobramatic to pins A & B of the 14 pin
amphenol; black to "a" and white to "B". Place the
contactor in the CLOSING CONTACTS position (see
Appendix for contactor information).
2. Plug the 115VAC plug from the unit into a standard
wall outlet or cut off the plug and wire it to the 14-Pin
amphenol; black to pin "i", white to pin "G" and green
to pin "K".
3. Tape off WC-1 red and green leads and turn off Posa Start switch as Posa Start is not used.
4. If the power supply has a Remote/Standard contactor switch set it to "REMOTE".
note: Some Miller amphenols do not have pins A & B. If this is the case do the following for the
contactor hook-up. Everything else is unchanged.
1. Connect the black contactor lead to pin "J" and cut off the white contactor lead (not used).
Place the contactor in the 115VAC contactor position.

The PA-M1 Control (P/N 005-0261) comes equipped with a 14-Pin amphenol and simply plugs into the
Miller power supply. If the unit is a CV/CC power supply operate in the "CV" mode; have the remote
voltage selector on "panel" and the contactor selector on "14- Pin". note - On the XMT series machines,
a Dinse style connector (MK P/N 153-0755) would have to replace the lug on the power cable of the
spool-gun.
Older style Miller CV power supplies without 14-Pin amphenols used a two prong twist lock for the
contactor and a three prong twist lock supplied an auxiliary 115VAC. Some units also had a standard
wall outlet 115VAC plug which can be used instead of the three prong plug.
1. To hook-up the WC-1 Weld Control or the Cobramatic cabinet to these units connect the black
and white contactor leads from the unit to the two prong twist lock plug (black to hot & white
to neutral). Change WC-1 or Cobramatic contactor to 115VAC (see Appendix for contactor
information).
2. Plug the 115VAC plug from the unit into a standard wall outlet or cut off the plug and wire it to the
three prong twist lock; green to pin with tang, black to hot and white to neutral pin.
3. Tape off WC-1 red and green leads and turn off Posa Start switch as Posa Start is not used.
4. If the power supply has a Remote/Standard contactor switch set it to "REMOTE".
