Hi everyone, Quick question... I know I can DC TIG weld with my Miller Blue Star 185DX, but is there any difference if I wanted to buy and use a Miller Thunderbolt AC/DC machine in the DC mode to TIG weld? The engine driven Blue Star lists that one of it's processes is DC TIG, but the Thunderbolt lists AC and DC stick only. I'm thinking it will, but I know there are more brilliant minds among you that can answer this question. Thanks!
