I said I'd give aluminium a go. I got some off cuts of 2mm aluminium for free. No idea what aluminium it is. For some reason it just wont pool. Once it burns through the oxide layer it goes crazy, sputtering on and off etc. Tried all sorts of settings. Cleaned and wire brushed before hand. Now I also have 5mm plate which I don't know what grade it is either, but I'm able to pool it control it and add filler etc. Could it be possible that this 2mm sheet I got is not weldable or is it just me ?? 5mm plate at about 160 amp is fine. Tried from 40 to 100 amps for the 2mm
