No ------- way im building tha thing, a ------- stun gun and running wires into a bucket of water, Sounds like like a death trap. I'd definitely do the welder though |
Re: I built my own welder, and you can too.
Electronics own me, but I've been wanting to try and build one of those to run on my trail rig.

Re: I built my own welder, and you can too.
swap i didnt know you were on here? Youve got a Turbo A20 project too? Your homemade welder is freaking cool... i never thought of that. Not sure how long that alternator is gonna last with that kind of a load on it, itll prolly depend on duty cycle.

Re: I built my own welder, and you can too.
damn, 3geez.com is really repping over here huh. anyways, i just happen to have an old gm 1 wire altinator in my basement. sounds like i got a new weekend project. we must have like 10 different a20a turbo projects right now

Re: I built my own welder, and you can too.
That's a great thing about alternators, is that they can run on 100% duty cycle.

Re: I built my own welder, and you can too.
how would you go bout making it a tig?
i do heating and airconditioning so we have tons of motors in the where house, i have argon tanks in the garage too, i guess i can go to hf to get a tig gun but how would i wire it all up? can you make a schematic of how it would all be hooked up with a coil also how many rpm does your motor do? |

While people do say that these alternators are 100% duty cycle, I know they are not made to take this kind of a beating. I got a cheap $5 digital thermometer, and put the sensor on the alternator. When it gets too hot I can just stop for a while and let it cool down. I also will be putting a fan on it. |

My motor does about 3450 RPM , and then it is stepped up to about 6000 RPM at the alternator. Edit: Accessory kit: http://store.weldingdepot.com/cgi/we...epot/AK-x.html Torch: http://store.weldingdepot.com/cgi/we...pot/WP9-x.html These torches have either 12 or 24 foot long cables. Torches have either have two cables (one for power, and one for gas), or a combined cable. Units with combined cables are supposedly more rugged. If you get a combined cable unit you need a power cable adapter: Power Adapter: http://store.weldingdepot.com/cgi/we...ot/105Z57.html |
