what this welder worth

[lx450landcruiser]

long story short a had a guy on craigslist offer me trade for some of my stuff, he has a CK Systematic push-pull Mig 300 Sm welder. Its used and i already have a miller 175 mig welder but he says this ones set up for aluminum. does that meas it just has aluminum wire? Just thought id post it up here and see what you guys think.

I see he has it listed for $1200. Push-pull feeder is good for aluminum. You can have a real long mig gun because the wire is being pushed and pulled. You would be using aluminum mig wire to weld aluminum.

CK Systematic used to make welders for snap on some time ago before Century starting making them.

I don't anything else about CK Systematic.

I'm sure someone much more knowlegable will correct me, but I thought all your miller needed was Aluminum wire and whichever gas it needs
That's what I remember them telling me when I bought my 125

Maybe he just means its CURRENTLY setup for aluminum?

You just need to switch the polarity around, use Argon instead of C25 or C02 and if it's not push/pull you would use a spool gun.

The aluminum wire is really soft, so it's better to pull it from the gun than push it from the machine. I have a Lincoln 125+ 110V machine that claims to be aluminum capable. However, theory and practice are two different things. If I set the wire tension too tight, the wire would birdcage at the machine. If I set the tension loose, the wire feed was not consistent. It was really frustrating to try and weld this way.
