I know this really isnt the right forum to post this; however a bunch of you in here are into welding. So i figured id share.

So how redneck do you have to be to make your own welder out of a car alternator?

That is the coolest thing I have ever seen.

*seriously considering* For $100 can you really go wrong?

TIG theory.. anyone have info/links as to the theory behind a TIG welder? I'd like to doublecheck his equipment is actually functional as such before I try building something like that. I have a lot more time than money.

 

keepin it grit

pretty crafty

 

Thats some hick ****...I know some people that would do that.

 

I think I hear banjos playin in the background...

 

I need to try this, with $150 u can't go wrong, anyone wanna type up a list of parts and where to get em/which car.

 

bump.. this is my winter project... good thing i picked up an old snow blower w/ a good running engine the other month for free and have a few alternators layin around in my garage.....

 

if anybody figures out how to make it work..lemme know!

I have fourteen broken microwaves (or just their transformers) lying about my room. I've been sourcing this shizzle for a little over a year.

I think DIY-Welder also has the alternator welder deal.

edit: fixed my busted *** URL... didn't need no stinkin' hyphen.

bad link, for me at least. :\

 

i used to have a video somewhere of a guy laying TIG welds in stainless using 2 car batteries in series, electrode clamped in a big tape covered thing with a regulator on an argon bottle feeding a piece of PVC pipe used as a cup. it was the G-to-the-HETTOest setup i have ever seen, but the bead came out looking nice. maybe strong too...

14 microwaves......what the hey!

J.davis is a bastard...he took the microwave I grew up with.

me and that thing had some good memories..

 

It looks like it will work, but is devoid of the HF (high frequency) unit that will allow the arc to start without touching the electrode to the pipe. You use a technique aply called "touch start".... drag the electrode a bit on the pipe and an arc will start, then move away to your arc distance. And it would be DC only. So you can do stainless and steel, but not aluminum ... which needs AC and a HF unit.

These types of alternator welders are well known. We used to use surplus aircraft generators 30 years ago. I think grobman surplus still has some in their catalog. I think they have a web site.

I am usually running around 100 amps max, with an arc voltage of around 15 or so volts on my Lincoln Squarewave........ so these alternators are a close match actually for this type of service.

If anyone is interested I have a old 300 amp TIG hose and head that I'd part with cheap. It is missing the cup, electrode, and electrode holder.

 

He actually mentions it's scratch start, yes.

I trust you to know that the equipment you're selling would be compatible and effective with the JY TIG welder above...? The cup, bowl, etc - these are all (cheaply) available from a welding supply store, correct?

If so PM me, I'm interested I seriously want to try this welder as I'm in dire need of a welder but can't afford even a cheapo MIG!

 

that is amazing. i might rig something like this together, just for fun. lol..

 

Okay, I saw this on another forum and now im seriously interested. Anyone know what to source the 130 amp alternator from? I got an extra 5hp lawnmower I can throw it on right now. Anyone know where to get the torch and jumpbox from?

 

Yeah, rigging one up from microwave magneto's is a well-known trick. Or maybe it's only well known to me, cause I have friends that make directed energy weapons, hrm.

They were in IEEE spectrum this month, heheh

that's a cool idea for the pulley driver...
