Which one is better?
I think its transformer welding because the alternator you need it spinning.
Well I have a second hobby, besides Jeeping, its electric vehicles. I have a glorified bicycle that I ride on the city pathways and in Fish Creek Park. I love the silence, no one knows its electric especially when I fake pedal it. The hills are a give-away though. I stumbled upon this topic (Transformer & Alternator Welding) while researching a DIY battery tab welder, to weld metal strips to battery cans, like C & D cells (26650, 18650)
I got one transformer out of a Frigidaire 1500W unit, and 2 others from older smaller units.
I think ideally I need 2 of the exact same transformers, to get a decent weld out of them.
Basically you cut out the secondaries, wrap a few winds of low guage wire and use clamps. Using 2 you need them in phase, I thought I needed the input out of 2 seperate circuits from house wiring in phase, that is not the case.
I use the panel outlet and the central vac panel, both dedicated outlets, like your microwave outlet, fridge outlet, deck, garage etc etc etc, by elec code that is.
I also found references to Alternator welding, and of course Lead-Acid battery welding.
Its basically just shorting out the leads. I have seen glorified units made with Adruino timers (mini computer timers, like raspberry pi kits) etc.
Mine is just a basic memory chip (came programmed from a guy in the UK), and electronic pieces on a pcb board, that I soldered up.
Never got into welding but this well be cool and perhaps a cheaper hobby, I just have no clue what width of steel I can weld.
They were using 5E electrode.
I will do up a bumper or something, then put in some CREE bulbs, a driver, reflector and housing. All cheap on ebay.
The guys selling the lights are making a killing.
Theres a company up off Edmonton Trail ~24st making the lights. Cool looking, they look solid and probably shed a ton of heat which is the key plus the throwing of the light.
