I'm not saying this to be a wise guy, but do you know Miller publishes all their manuals for free? You can go to their site and look up the manual and get a part number for pretty much anything....including that twist connector. I'm pretty sure Miller calls that the "Cam-Loc" style.

You can actually buy small spools of steel wire that will work in the 30a gun...more frequent spool changes than a wire feeder, but a lot cheaper.

 

I'm not absolutely certain but I think that power source is a renamed Regency which had the ability to use a feeder such as an S-22.

 

Yes an S22 feeder can be fitted to the Spoolmate. I did it back in the early 90's and you are correct it was later called the Regency. Nice little package.

 

No worries, i did that and wasnt familiar with the cam lock style plug, just wanted some confirmation before i bought one. Also i could run steel wire from the spoolgun, but i think id prefer a real wire feeder.

 

The spoolmate 200 i have came with a 4 pin spoolgun plug on the front and a 4 pin feeder plug on the back. The 4 pin on the back is for the S-52 115 volt feeders. a new R115 could easily be connected. We went inside mine and made some changes and mounted a 14 pin feeder receptacle on the front. so I can use it to test both 24 and 115 volt feeders. the welder is basically a millermatic 200 with the feeder removed.
The 4 pin spoolgun plug is for the spoolmate 1 or 2 just have to make sure which one it is set for. one uses ac voltage and the other uses DC.
