Fixing Kitchenware & Vacuuming down a Dry rotted Tyre!, May need to try and reseal the bead so It stays.
Wow that is so cool! I never knew about spot welding before this. Thanks for showing.
store bought spot welders have two big hinged arms that pivot so you can place the work piece. Google image search spot welder, I am sure you can make the arms if you want.
Cool to know that tx will power it. Ta
ye home made spot welder is a mad idea, why go out and buy one when you can make one and besides any decent welder nowdays costs a fortune to buy.
A bit of a silly question, but how did you not get shocked when you were holding that colander? A great little invention nevertheless!
@OldTimeForties The output voltage on the transformer will only be a few volts. Also, the secondary coil doesn’t reference to ground, so therefore, no electric shock.
The idea here, is to ‘trade-off’ volts for amps. Turn down the volts, & the amps go up, thus a lot of heat is generated, suitable for spot-welding
Even if he was to grab both output terminals ( Not advisable! ) I’m sure that the shock, if any, would only be a slightly unpleasant tingle.

@OldTimeForties The voltage is too low for shocks or electrocution:)
Good weld-job on the colander!
If the weld-amps were too much, I’m sure that they could have been reduced by using the variac on the input. Say for example you turned the variac down to 200v, that would’ve reduced the weld-amps enough to prevent holes from forming in the colander.
But hey, it’s a colander, they’re supposed to have holes.
It’s also nice to see that BAZ has come out to play!
YAY !

@FukinExplosions Ah, today has been a Learning day!
I used to operate an industrial spot welder, and the magnetic flux that radiated off of it upon strike-up used to make metal things around the workshop close to it move around the place! Spanners on workbenches would spin around, metal swarf would form funny shapes, and if the user had a watch on his wrist, it would display silly things or go haywire, as I found out when it played havoc with my £90 Accurist watch!! Grrrr!

@OldTimeForties it’s only 6 Volts Peak, Nowhere near enough to penetrate the skin!, This is what’s called a Step Down Transformer!
