Byron,
Very cool trick. Thanks for sharing.

I am so going to try this on Monday.

What I don't understand, is why does it work?

I also don't understand why you can't buy metal tips, and simply use those, instead of the copper units.

Its soooo simple.... but the best ones usually are!

It doesn't look like he even used very much heat to get the joint. I'm impressed!

Its simple Ian, its "resistance welding" and your using the steel to cause resistance/heat .
It made me feel old, my journeyman when i was a 2nd year apprentice taught us that one 40yrs ago

First of all great tip but....

DON'T use REGULAR sTEEL!!!!

This will contaminate your aluminium!!!

So if you do this use Stainless steel strips around 0.6mm thick.!
And about 1cm height and about 15 cm long and after spotwelding you can easely peal them off.
