I use 75/25 for a couple reasons. I like the ease of 
cleanup, it makes good solid welds and it's what I've 
used most of. I typically don't use the Hobart on 
anything thicker than 1/8", it just doesn't have the 
duty cycle to go more than about 15-20 secs.

I've only tried GMAW with straight CO2 once and didn't 
have a problem with how it ran.

Reasonably priced in Alaska is undoubtably different 
than somewhere nearer civilization. Still, It's gotta 
be a lot cheaper to use CO2.

For the thicker stuff I have the Ranger-9 and for lots 
of weld I have the LN-25 wire feed and flux core. Once 
I get the shop up and start equipping it an AC/DC 
tombstone is coming home.
