That's a great video review on the 160STH. I wish mine had the dial on foot pedal when I purchased it. I had to resort to making a mechanical stop that is adjustable so I can manually pulse with the max amps limited when welding thin sheet metal. The 220 to 110V pigtail is another item I wish I had. If only I had waited 8 more months before making my purchase (the money would have been LONG gone if I did!). It's nice to see the options are there even for the bottom of the barrel DC only TIG machine. Cool stuff. Now get to welding some projects! We need pics!
