    A S-74mpa, is supposed to run with a XMT 350mpa power source, The 74M is supposed to run with a XMT 300. The XMT350 needs the likes of a Optima pulse control for it to work

    When for my XMT 350 CC/CV to pulse Should I buy that Wire feeder(Head)?

    You need to stick a optima controler in between the machine and the feeder.

    If the emphasis is on the 74M wirefeeder, the answer is, not necessarily, You could even use a 22A. Most of the Miller wirefeeders between these two models would work. The Optima controller modulates the output of the XMT 350 cc/cv power source independently of the wirefeeder, but passed though the wirefeeder. If the 74M is the one you like, go for it.

    Perfect, now I understand the you said. I didn't know of the existence of Optima, This is really cool. The Optima is like the panel of the "Invision 456MP". Thank you very much!

    The 74M, is kinda crabby to work with, almost need a technical degree to figure out all the settings. Thats why I didn't suggest it. The Opima is easy, set it and forget it.

    Actually I'm a technical of the Miller I work in maintenance and the S- 74 Mpa plus I know well, but I never put with xmt 350 CC/CV, I'll do it.


    P.S. Sorry For My Bad English, I don't speak English, So I write a lot wrong.

    Yes really. Today I did tests with a "XMT350 CC/CV" and a feeder S74 MPa, really no worked in "Pulsed MIG". I saw two principais diferences


    1st- When set "Pulsed MIG" between the sokets of the remote 14 receptacle soket H to G don't have voltage (Voltage feedback; +1 volt DC per 10 output receptacle volts).


    2nd- The XMT350 cc/cv don't using the sokets L and N (Wirefeed speed command, 0 to +10 volts DC output signal from wire feeder) and the soket M (CC/CV Select; 0 to +10 volts DC)


    Because of this the feeder don't show Voltage, show just wire speed and don't have Weld Output.
