on the sump for my saab engine it was 4mm thick cast and it welded up lovely using around 90-100 amps, can never know exactly as i just give it more pedal if i need it. cast ali is always a strange thing to weld some times it melts like butter and other times it is a pain to get heat into, just depends on the composition.

Hi, do you actually need to weld the plugs in? you could make the plugs with o ring grooves and a tight clearance fit and use a bolt and washer to hold in or make them top hatted and bolt in.
no welding also means no distortion no grit blasting no chemical cleaning etc just a plain simple engineering solution. Ray |

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! |
