Thought I'd share my Weldernator

[clarkjw24]

inside my alternator case, the capacitor looks different, but everything else looks the same. My capacitor just looks like a normal cap; just a cylinder with one lead coming out, then a bracket where it was grounded and attached to the case. Will mine still work?

Yes.

 

[clarkjw24]

Do you mean reverse polarity? I have the same question.

Yes, reverse it if you are welding on your own rig.

Now...I have heard of this....but have never seen it! WOW! Too cool!!!!

Notice that this 8hp welder is using rectifiers to weld with DC current.

There's no way you could use stock alternator rectifiers like this. They would burn up, but they are probably also Zener (avalanche) type that would clamp the voltage to 30-45V.

What gauge of welding cable should i be looking to buy for this setup? Any idea of the amperage it is capable of putting out when all is said and done? surely it's not 115v and 93amp.

 

[wazzabie]

are there any dangers of frying the eletrical syatem doing this?

 

[crash81]

cool

 

[gotblazers]

whats the capability of this as far as metal thickness and types of metal?

like sheet metal? or roll bar n bumper tubing kind of stuff? Btw i have a 6.6l v8 so i cant hit very high rpms for the alt.

If I'm seeing this right, it looks like the Welder's alternator is stand alone as far as electrical energy is concerned. It might raise hell with your electrical system if welding on the same vehicle though. Remove your batt. cables and it shouldn't be a problem.

Wazzabie, I've noticed you've recently came to life here again, and bringing up some old threads and/or frequently asked questions. Have you been in hiding for a while?
No flame, just curious?

The engine has to be running in order to use the "weldernator" and if you disconnect battery cables while the engine is running you risk the chance of blowing the diode trio in the charging alternator.

Thanks Scott, I guess that just didn't register with me.

You just need to find the right RPM to get 60Hz, but the voltage would prolly still be wrong. I wouldn't use it to charge my iPod, but it would be fine for a $20 harbor freight drill during a field fix.

Another problem is that without the diodes, you will get 3 phase AC out, not standard wall voltage single phase power.

could you tell us more about the rest of the wiring for the weldanator like the on off switch and relay

 

[BGKYK5]

Clark, by naming it the weldernator, you know you are inviting comparisons to this guy:

Any issues with the Weldernator since you put it together? Use it much?

 

[mudbuggy]

so what is the actual alternator that is used for this a 10si or a 12si?

Just curious, but why do you have to reverse polarity when welding on your own rig?

so you don't 'fry' your own electrical system!
