The older Linde CV machines are connected as follows:
1. Connect the black and white contactor leads extending from the WC-1 Weld Control or the
Cobramatic Cabinet to the 6-Pin metal Pyle-National plug; black to pin 3 and white to pin 5.
Place WC-1 or Cobramatic in the 115VAC CONTACTOR position (See Appendix for changing
contactor).
2. Plug the 115VAC plug extending from the WC-1 or Cobramatic into a standard wall outlet or
cut off the plug and wire the black wire to pin 1, the white wire to pin 2 and the
green wire to pin 4.
3. Tape off WC-1 red and green leads and turn off Posa Start switch as
Posa Start is not used.
The newer ESAB/Linde/L-Tec CV machines are connected as follows:
1. Connect the black and white contactor leads extending from the WC-1 Weld Control or
Cobramatic Cabinet to the 7-Pin plastic AMP plug; black to pin 1 and white to pin 3. Place WC-
1 or Cobramatic in the 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 the black wire to pin 1, the white wire to pin 2 and the green
wire to pin 4.
3. Tape off WC-1 red and green leads and turn off Posa Start switch
as Posa Start is not used.
Some ESAB/L-TEC CV/CC machines have 19 pin (J1) amphenols and are connected as follows:
1. Connect the black and white contactor leads extending from the
WC-1 or the Cobramatic to the 19 pin amphenol plug; black to pin
a and white to pin C. Place WC-1 or Cobramatic in the CLOSING
CONTACTS position (see Appendix for contactor information). Pins
U & V can also be used for contactor.
2. Plug the 115VAC plug extending from the WC-1 or Cobramatic into a
standard wall outlet or cut off the plug and wire the black wire to pin
a, the white wire to pin B and the green wire to pin d.
The MultiPower 460 units do not supply 115VAC at the 19-Pin.
3. Tape off WC-1 red and green leads and turn off Posa Start switch as Posa Start is not used. On
the Cobramatic System hook up the Posa-Start lead to the Power Supplies ARC GROUND and
use PosaStart when welding aluminum only.
