Trust me, you have missed nothing at all!.Never heard of aluminium arc rods, didn't know they existed.
Interesting.
Any pre heat?I sort of like them. I made 2 aluminium boxes out of 4mm sheet last year and they turned out ok.
These were welded with AlSi12 electrodes which worked a lot better then the AlSi5 electrodes I tried a couple of years ago.
When you have the settings right the slag comes of easy enough ones the weld cooled down a bit. The flux is salt based and very hydroscopic, so you have to use hot soapy water and a hard brush to clean the welded areas to prevent corrosion.
