you mean to run grinders and other brush type motors.. (no variable speed drills though)

Yes with full field coil current and the rpms maxed out, you cun run those off of the welder output. just wire in an electrical box.

Another friend's dad has a second alternator in his Jeep setup as a DC stick welder, just in case he breaks something when he is out 4 wheeling. I believe this is similar to your idea. Neat idea using the sliding light dimmer for the foot control.

I have attached a Word document that I made from your posts along with some of the posts where the content adds to the discussion. Hope it helps in creating an all encompassing document in the future.

Now, if someone could just come up with a home made plasma cutter...

Regards,
Rob
Right on.. I would do what i did though and get rid of one of the alts and wire in a ford regulator, so the alt will charge and weld when you need it.. its very reliable and will be a lot neater under the hood. I had one on my old trail rig, and i have one on my 67 chev ramp truck.

A plasma cutter is pretty simple as well.. you just need compressed air and alot more power and volts. I was about to do it, when I got an 80Amp plasma machine for free... they said it was broken and wasn't worth fixing, a couple small repairs and adjustments (both $$ free) , and I got a sweet plasma cutter that will cut 1" plate.. whooohoo lucky me

it happens all the time keep your eye out.. once the machines mess up, they think its cheaper to by a new one.. but for a handyman they are simple to dial in again

S10Fan has emailed me a 15-page PDF with photos and diagrams for a DIY TIG welder. I'm looking into the copyright issues right now. If anyone has any information on freely posting this PDF file, please PM me ASAP. The author is "John Mills".

DIYTIGWelder.com is one lead, but they've been taken offline. We should be able to view some of their pages at Archive.org to see if the same file was offered for free, but Archive.org is temporarily down right now too.


Meanwhile, here are some related resources listed on other websites:

Doc here,

The Name John Mills brings "No Results " on a copyright documents search..

So I would say this material is probably public Domain.

It may still be under copyright, even if it's not overtly registered. grouch is very knowledgeable about digital rights management and intellectual freedom, maybe we'll see what he has to say about this.

If not, we can just do what lowROLLERchevy is doing in this thread. We had to take T-Bucket plans off of the board due to copyright concerns, so he's drafting a set of plans to give away for free to the rodding community .

We can do the same thing with plans for a DIY TIG welder.

Now that is nice, I couldnt understand why you would need all the overhead of an electric motor and alternator. Solid state is sooo nice and clean im gonna start building that one!

Thanks fo that link!

I might have to just dust off my old electronics text books and re aquaint myself with some things.

I need help over this brainfart I have though. Admittedly I need to read more on TIG to better understand, but looking at the schematic....

The 240AC to BR1. Is that an input or an output? I mean do you plug this into your house 220v outlet or what is it for? Not sure I follow.

Can you be more specific about the specs on the electric motor you are using? What about the Delco alt? What would be a likely vehicle to look for such? (I'm a Ford guy. Not a lot of experience with Delco alts.)

Looks to me like that is the same 240vac supply that his 5hp motor uses and he just used that for the 240v to 25v step down transformer for control voltage.
