    Default Miller CP-200 spoolmatic 2 gun shot, how to rewire for spoolmatic 30A

    Am attaching a picture of the front of the welder. The plug-in for the spool gun is below the two switches on the right side of the photo. I am wanting to buy a newer spoolmatic 30A that has a 14 pin connection. Will this work and how do i wire it?

    Well, you have no 24Vac on that ole machine. So you'd need a stepdown TX 120/24 50 VA, a 24Vac DPDT relay, a 14 pin amphenol clocked between A&B. some wires and some electronic know how. Then you'll need a WC-24 controller and gun

    A wc115 would be needed to hook the 30a to the cp200.The 30a does not have a motor control board in it, it need an external "weld controller" to run the motor in the spoolgun.There are 2 for the 30a, the wc24 and the wc115.The wc24 uses the 14 pin to the machine and the 10 pin to the 30aThe wc115 uses 115v from any standard wall outlet and give the required power and motor control on the 30a
