Aluminum oxidizes instantly. But,the oxide is transparent,and protects the metal under it, so it SEEMS to resist oxidation.

my experiment with alum didn't work. I think what George says that alum oxidizes instantly is the reason.
BTW, I got my spot welder to work a lot better by putting a new copper connector on it. Also, I think it's important to clean off any coatings. I tried spot welding coat hangers and nails and found that some of them need to be sanded because they have nasty gooey coatings

I'm back! I added a handle from a second microwave I got and dismantled for another project
I wondered if it would do resistance soldering of brass and copper so I took a 4ga copper wire and a brass housekey and in just 1 or 2 seconds it created enough heat to solder the 2 parts fast
I got a switch on back of the unit and added a foot pedal today. The pedal, from Horrible freight, is the worst kind to get IMO. I thought it stops power when foot removed (fail-safe), but it doesn't. You have to tap it again. Another HF model is the fail safe kind. I got it on impulse buy without realizing and it would take several hours driving to return it so it stays
(warning about microwaves: short the capacitor as it could carry a lethal charge. Also ensure it's not plugged in. Also, the magnetron has 2 nice magnets in it but breaking the fluids surrounding them could kill. Also, in making the wood parts, if you slip and fall into the table saw, that could be lethal, as could slipping on the ice outside)

In Europe household power is 220V/50Hz (actually 230V) single phase instead of 110v/60Hz.
In the video Lazze told about the trick coming from an old Italian guy, so probably he intended 220V as "normal household power".
BTW, our three phase is 400V, even if almost everybody still call it "380V" according to the old value.
