An external feeder such as an S-22A can be used with the Millermatic 350P but you will not be able to pulse with it. You would need an MPSA adapter to make it work (pn 195019).

Well basically the MPSA adapter will plug into the 10 pin on your machine and also has to be plugged into a 115 volt wall outlet.
The MPSA has the standard Miller 14 pin on the front of it that will give you what you need to operate a 24 volt feeder such as the S-22A.
You can choose spoolgun or it will default to spoolgun when the trigger to the external feeder is pulled so the drive rolls in the unit will not turn.
As I said before you will be limited to straight mig in this situation so you would set it up according to the gas and wire being used and the material being welded. The mig chart on the flip down door should get you started.
