Here is a link for the welder. Lincoln Electric

It's a lincoln 100 with the additional Mig conversion, basically upgraded to the 135. I've got the regulator and hose for gas and the CO2 adapter. I've also got the hose and gun for flux core welding.

Lincoln has it currently for $517 plus shipping at 50lbs. It's like new, so I won't sell it unless it's reasonable. Probably around $375 including the custom built metal welding cart on wheels, but at that price it would be without the co2 bottle.
