I have two fronius transteel 3000 pulse welders for sale, both in flawless condition only ever used for aluminum MIG. I bought from a tech school in hopes of using but I went with a mobile rig instead. You dont need a special gun to use for aluminum just the regular one you use for everything else. They do not come with ground cables but can be ordered online. 3500ea or 6500 for both obo. I also have a miller 70 series wire feeder im selling for 1500 all ad it to the listing.
