spool gun

[tnjind]

I am looking for a spool gun to hook to either my esab 450i power source or my syncrowave 350.
I know nothing about spool guns, never used one or even seen one being used. But it was the same with tig.
What interfaces with these power sources? (spool gun brand,styles sizes...)
I am wanting to weld aluminum at a faster rate then tig. For boxes tanks...
Thanks to all who responds, Tim.

You need a CV powersource, which your Syncro 350 is not. What about your ESAB?

The synchowave is a 350lx, if that matters.
The esab is a svi 450i cvcc.
I would like to spoolgun it, but I am thinking about replacing it in the future with a MM251 or 252, so if I bought a spoolgun I want to be able to use it on both (current power source or new).
Thank you,
Tim.
