thats the settings for pritty much any make or model of tig i would be using ash as long as its square wave form even more for sine wave old tigs.
dont want to be there all day welding the thing
or trying to make it hot
but yes its defo not made on this side of the world but not even the big names are made anywhere near europe thease days (trust me i have been inside them)
unless your spending real big money or realy know what your buying (ewm would be my choice btw)
i just need somthing that works and does my hobby bits not worth spending more than my build and i dont have 3ph so cheap s/h ac/dc tigs are like flying pigs
god i see sets selling more s/h on ebad than i sold new a couple years ago!
