Nice used aluminum welding set up. The machine is S350 power wave and the feeder is Lincoln Power Feed 10M digital with pre programmed settings. The s350 has smart technology that allows it to adjust to whatever power source you supply it with, single or 3 phase and 208 and up on the power. There is 50' of power cables and gas lines with the feeder so you can work well away from the power source. Trades accepted and several available. IF you want to see specifics on the machines just look it up and Lincoln can tell you exactly what it will do. I will answer any other questions that you may have.
