Ok I've just tried to weld a lad at works push bike seat stem to its post, now the post pools up no problem but the stem won't pool at all, now I know people are going to ask what amps,frequency ect ect all I can say is I went from one end to the other with them all even went to DC at one point. I cleaned wire brushed wiped with acetone sanded it cleaned again it just won't pool up? Can you get unweldable aluminum
