The Prince XL Spool-gun may be hooked up to the BetaMig 200 or the BetaMig LF by using the PA-G1
Control (P/N 005-0264) as follows:
1. Open the left side of BetaMig.
2. Splice the red and green contactor leads extending from the Control to the spade connectors
below the wire feed motor on the deck (trigger connection).
3. Remove the right side panel of BetaMig and locate the small control transformer next to the input
voltage taps. The transformer is marked 110/110 on one side and 24/24 on the other.
4. Splice the black wire extending from the Control to one side of the Spade 24 and the white wire
to the other Spade 24.
A WC-1 Weld Control or Cobramatic System may be hooked up to these units as follows:
1. Plug the WC-1 or Cobramatic Cabinet 115VAC plug into a standard wall outlet.
2. Install 1/4 (.250) wide female spade connectors to the black and white contactor leads from the
Cobramatic Cabinet. Inside the Wire Feeder portion of the BetaMig console, remove the torch
trigger leads from the spade connector and plug on the ones from the Cobramatic contactor
leads.
note: The feeder inside these units will also be turned on,
so disengage the spring tension on drive roll.
The BetaMig 2510 Kit (P/N 005-0205) is the same kit for the Millermatic 250 and plugs directly into
the front panel on the front of the unit. It includes everything needed to interface to this power supply.
However, the printing on the kit identifies it as a Millermatic 250 kit.
A WC-1 Weld Control or Cobramatic System may be hooked up to any of the BetaMig systems above.
In each case, the 115VAC plug from the Cobramatic Cabinet must go to a standard wall outlet.
On the BetaMig 250, female spade connectors have to be installed on the WC-1 or Cobramatic
Cabinet's contactor leads (CLOSING CONTACTS position) and installed like that listed in H-1 .
On the BetaMig 251 and BetaMig 2510, splice the WC-1 or Cobramatic Cabinet's contactor leads
(CLOSING CONTACTS position) to the trigger leads coming from the back of the Hobart's torch
connection to the welder.
note: In all three cases, the feeder inside these unit will also be turned on, so disengage the spring
tension on the drive roll.

The WC-1 Weld Control and the Cobramatic Cabinet is connected to Hobart CV and CV/CC power
supplies as follows:
The contactor is always found on pins "A" and "B" regardless of the type of amphenol.
Most of the Hobart CV power supplies use a 5-Pin amphenol.
1. Connect the black and white contactor leads from the WC-1 or Cobramatic to pins
A & B of the 5-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 extending from the WC-1 or Cobramatic into a standard wall outlet.
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: If unit is a CV/CC power supply use in the CV
mode. If hooking up a Cobramatic Cabinet, it is
recommended to hook up and use the PosaStart
feature.
