I can't find the original thread but I said I'd report back on the type of aluminum MIG wire I've been using very successfully without a spool gun.
The reel simply contains the label Al5Mg -- which I assume to mean that it has 5% magnesium.
I couldn't see a manufacturer name but I found an Italian website (I was pretty sure the wire was Italian in origin) which confirms that it has 4.8% magnesium.
It also says that it's an alloy designed for welding 5000 series or for welding 5000 and 7000 to 5000 series and the resulting weld is suitable for anodizing.
