The WC-1 or Cobramatic can be connected to the Thermal Viking 210/250-GM power supplies as
follows:
1. Connect the black and white contactor leads from the WC-1 or
Cobramatic to the spade style terminal inside the door above the wire
feed motor of the Viking unit. The contactor leads will replace the
existing wires going to the two spades on the right side. Place the
contactor in CLOSING CONTACTS position (see Appendix for contactor
information).
2. Plug the 115VAC plug from the WC-1 or Cobramatic cabinet into a
standard wall outlet.
3. Tape off the WC-1 red and green leads and turn off the Posa Start switch as the Posa Start will
not be used.

A Prince XL Spool-gun may be connected to the Viking 210/250-GM power supplies without the use of a
control module by using a MK 003-1623 Panel mount kit with 4 female (.25) Forked Tongue connectors.
(See the NOTE below - No WFS at the Prince XL Torch).
1. Punch 1" hole in the front panel approximately 2" below meter cut-
off hole.
2. Cut off the blue, green and white (or yellow if there's no white
wire) wires from the back side of the 003-1623 panel mount. Crimp
the female spade connectors to the brown, orange, black and red
wires.
3. Mount the 003-1623 amphenol in the 1" hole. Inside the hinged left
door there's a terminal strip with four male spades. Remove the
existing wires and fasten the wires from the amphenol as shown
below:
NOTE: With this hook-up, the WFS (Wire Feed Speed) Potentiometer on the Prince® Spool
gun is unoperative. WFS will be controlled by the control on the front of the welder.
A Prince XL Spool-gun may be hooked up to the Thermal-Arc 300GMS, Fabricator 210 or 300-LF Welder
with a MK 005-0261 Miller style 14-Pin PA-M1 Control (See section M-1 ). Note - Cut off the lug on
the Spool-gun power cable and install a male Dinse style connector (MK P/N 153-0755). Exception
- Fabricator 210 that has a specification with an "A" at the end (See Note 11).
A Cobramatic system may be hooked up to this same power supply. The instructions in section M-3
would apply. A Dinse style (MK P/N 153-0755) connector would be needed on the power cable from the
welder to the Cobramatic Cabinet.
note: a prince XL Spool Gun can be connected to the fabricator 250 using a WC-1 only.

A Prince XL Spool gun may be hooked up to many of the Thermal-Arc engine driven welders. The
Exciter and Hog units are CC only and need a WC-1 Control Box that is CC Posa-start Ready and
connected with a contactor box as shown in the Appendix. The Predator and the Explorer units are CC/
CV and normally come without a contactor. Then a WC-1 and a Contactor box is needed.
