Every man needs a hobby. And this is a more recent hobby I've been researching for the last few weeks. So basically, lets start here. I ordered this kit yesterday on ebay. It's a 21 Plate HHO Hydrogen Cell With Bubbler & Electrolyte Container + a bunch of wiring. I don't know why, but I think these things are extremely cool. Even though they can't be used to weld iron (I have an arc welder for that) they can be used on everything else .. platinum, copper, brass, aluminum, porcelain, stone, glass... hell, you can even weld fire bricks together with these things. They produce a very hot flame of 2,800C or 5070F. Which is close to oxy acetylene. Except you're using water as the fuel. Here is a dude melting lava rock with one... (skip to 5:30) NOW, here is my problem. Most of these guys use car batteries to charge these things. I don't have any car batteries nor do I like the idea of charging a battery just to use it for 30-60 mins till it dies and you have to recharge it over and over and over. Not to mention car batteries are heavy as hell (like 45lbs). AFAIK they put out 13-14 volts and around 15 amps. So I was up in my attic a few days ago, noticed a big bag of old IBM laptop chargers and a light went off in my head. "If you can connect batteries - to + (to stack current) why can't you do it with ac to dc converters"? Since my tester only goes up to 10 amps, I tested each DC converter 1 by 1. They all were putting out around 19 volts and 4-6 amps each. 1 was a bit weak putting out 16 volts and .5 amps. But the rest were still good. So I connected 6 of these bitches together and hotglued them to a board (I left the weaker one off the board/on the floor since I may replace it). Not sure if you can see but here is the rating on most of them... 100-240 V AC - 1.5 -.8 AMPS to 19V DC - 4.5 AMPS I stacked them all properly, and this is the voltage I'm getting... This is when I fired up my temporary HHO test cell (it's a small, shitty wet cell), and realized I need thicker gauge clamps... The clamp immediately arced and welded itself together. So I'll be increasing the gauge of both the wire and clamps. Now this is where things get tricky. If I estimate how many amps this thing is producing, based on ideal science, it should be... 4.5 + 4.5 + 4.5 + 3.6 + 6.6 + .5 = 24.2 amps So I'm GUESSING that this system is producing 105 V DC @ 24.2 amps? My main question is, do DC converters stack amps the same way they stack volts? I have no way of testing how many amps this system is actually producing. I tried with my meter (that says not to test anything over 10amps) and the amps were bouncing from 2 to 10 to 4 to 5 to 10 to "error" so I quickly unplugged it w/out breaking it. Then I went to Lowes looking for a new meter and NONE of the meters go above 10 amps. They had like 20 different meters but they're all limited to 10 amps. There are meters online that go over 10 amps but I can't justify spending $80 or more just to run 1 test. If I know (roughly) how many amps this thing is producing, I can calculate the LPM (liters per minute) for when the kit comes. But I guess the only thing I can do is wait till it arrives, wire it up, test the LPM (liters per minute) then roughly judge whether it's getting enough amps or not. -BB ps. I just got these weird idea. I found a small box of car fuses in my tool box. 5 amps, 10 amps & 15 amp fuses. Should I just buy a series of fuses, like 10amp, 15amp, 20amp, 25amp then try blowing them out 1 by 1? AFAIK, this wouldn't give me a precise measure. But fuses are cheap and if I blow a 20 amp but not a 25 amp, then at least I'd know I'm somewhere in between 20-25 like I'm guessing..... correct?
