The Lincoln Magnum Spool Gun Module appears to output 5-28 VDC, so close enough for Rock 'n Roll.

Look up your manual at the above link. Post your serial # in this thread. Ascertain if you have a 10 pin plug, a 14 pin plug or you need an optional module for a spool gun. Then you may get more relevant info.

I think Cruzier out in Edmonton builds a magic box for that connection. I thought the voltage out from the 256 was not the same as the 30a uses. And everyone loves the 15/30a for a spool gun.

I don't know zip about it but the description of 3T sounds to me like it might be intended for some kind of automated TIG welding.

Make sure you supply yourself some air if your in there, inert gas in enclosed small space.
