I am getting a lot of conflicting stories. What spoolguns can I run off both my millermatic210 and my bobcat225? I know I need a adapter for the bobcat but which one? a WC-115A or a SGA-100C ? will the wire be hot all the time?

I looked at the chart, according to that my 210 requires a spoolmate3035 and for my bobcat a spoolmate 3545(which is no longer produced) or a spoolmatic 15a or 30a. I've read elsewhere that I should be able to get one spoolgun for both(with an adapter for the bobcat). I am hoping to find someone here that has done this. What are my options?

thanks
