I have a new Everlast TIG 210 EXT with a single control knob. Apparently the manual is not out yet as I don't have one. Does anyone else have this unit or can give me some suggestions/advice on setting up to do thin sheetmetal (16 Ga.)? The unit came with two torches, foot pedal, regulator, 110 V plug adapter, 220 V cord/plug. I have stick & MIG experience, but completely new to TIG,so any advice is appreciated.
