Yofish, From what I see with my MTS250 all that needs to be done to a 30A gun is to put a Dinse connector on the power cable and buy a 7 pin connector from everlast. Then just follow the wire schematics for both the 30a and MTS to connect it. I think it will even work with the synergic function. I am not sure why Kempy hooked his power lead to the euro mig gun connection. The 30A should hook up just like an Everlast spool gun does. Unless I am missing something .
