lincoln "idealarc" wire-matic 250 - questions

[cp0ff]

I was recently given a lincoln wire-matic 250 mig welder.

I have arc welded alot and mig welded a little in classes I had along time ago, but liked it and had a bit of a knack for it for a while.
I havent had access to a welder since.

now I've got what appears to be an industrual-sized lincoln.

from what I can tell, it is not made anymore, and the nice manual and
parts list I printed from the lincoln site call it the "idealarc" wirematic 250.

I was wondering what i should look for in a replacement gun, as it seems the available gun types are specific to model and then categorized by amperage rating and intended use (is this right?)

anyone else have one of these beasts? or know anything about "idealarc"

I am excited to have such a monster of a welder and am looking foreward to collecting all the rest of what I need to get this baby sizzlin'

any info or tips would be greatly appriciated.

thanks!
