High voltage HHO by IronHead

@gotoluc;
Y'all gonna try and weld stainless with a MIG?   I gots one (Lincoln 255) and every welding shop sez I need to TIG stainless if I wanna decent job.

Lemme know how it comes out.

I ain't gonna buy a TIG fer this project jes yet... found me a good welder, an I can pay him fer quite a while fer what a TIG would cost in Turtlebucks.

Turtle

Hey Turtle. Did you know you can buy or build a conversion torch for your mig. all ya need to do is get a tig torch that will fit the wire nozle on yer mig. the tig tip screws into the mig handle and the gas port flows through it. we call it a poor-mans tig-rig. Hefty to handle but but it works well. you just need the right shealding gas for stainless. Like aregon/C02 in a 50/50 works ok. You wont be welding aluminum with it . it takes a high freq machine for that. but the mig will weld stainles and other odball alloys .. If memory serves the last setup i did was like 30.00 for the parts and tungston. whats really gonna cost you is the stainless to practice on,

I havnt tried this yet but it is said an old wire nozle bored out to 5/32'' and a short peice of tungston (1''-1/14) incerted in to it friction fitand screwed back in to the mig stinger. Now you need to unhook the wire feed tensioner so it wont feed wire to the gun and with the right shiending gas yer all set to burn your first holes through a perfectly good peice of stainless.

Now the guys down at the weld shop prolly wont be of much help,cause they want to sell you a tig machine. Really the only difference is the stinger (Torch tip) and its gotta be a DC machine. Wich all migs are. Like i said not pretty and a little odd to handle compaired to a real tig but it will work.

Hope that Tip.. (Pun intended ) helps somone. Moab

@Turtle, I'm looking into a Mig at this time. Still got to figure if it's worth it or not .

@Moab, thanks for all the great welding tips, (pun intended)

Thanks, ZFF fer  posting yer observations.   It helps us all grasp the outcome of yer trials.   

I'll see my stamping shop classmate later this week; he may have some dies ready to run, and will take some strips of 26 ga 304 so's he can squarsh 'em.

I gots me some perf plate to work with that perpendicular idea as well.  Earlier it was mentioned that epoxy don't do well in a caustic environment... but I gots some structural stuff ["bond yer 1/4 panel on yer ride" type] that's been screamin' "TRY ME" from the shelf.

What better use on a critically aligned stack, held true by shim spacers, then glue and remove spacing stock.   This later this week hopefully.   

And, if I can get it built, a flashback bubbler that uses HHO to recirculate the electrolyte, without a separate pump.  No Kidding!

Oughta be an interesting week.

@Turtle - I can't wait to see what you create!
@d3 - Here are my measurements that bear out my findings:
Increased the electrolyte concentration to double the conductivity. Whereas beforehand I needed 75V@10A (750W) to fill 500mL in 45 seconds, afterward was 32V@9.6A (300W) which filled 500mL in 60 Seconds. Extrapolated that's 500mL in 45 seconds at 400W. Electrolyte concentration was the only change.

With the concentrated electrolyte I drew 2.15A at 13.6V for 29 Watts. At this wattage it took 1050 seconds to fill 500mL. 1050/45=23 times slower. 400W/29W=17 times less wattage. Roughly 1/20 the wattage produced roughly 1/20 the gas. If it was relative to amperage, my gas production would have been about 1/4, not 1/20.

I will have more accurate results to present later but I'm pretty sure about this conclusion.

I have been trying some NaOH for the past couple of weeks mixed at various concentrations in the water plus different types of water. Change over to Baking Soda to try for a while. This video I am using Baking Soda.
   The NaOH seem to suds up to much and the bubbles would turn back down in the water. I have some KOH ordered and I am going to try that also with this cell.
   I will agree with ZFF that as the temperature rose in the cell the amps would go up slightly. Started out a approximately 9 amps cold and went to 12 amps when the water was about 145 degrees.
   This video I also put some plates every 4th spacing about 1/8 inch apart in the middle of the cell. Seems gas production went up when I tried this.
   Just wondering if anyone has ever used High-Density Polyethylene? The black stuff that they use to make truck bed liners for a box to put the cell in. Seems it will stand high temperatures than Nylon or UHMW.

 I have a small Cambell Hausfeild and it works great. I just bought SSwire for it and does the job. If you want a cheep TIG unit go to Harbor Freight , I bought one and it's just fine 200 bucks!  it's not the type welder it's the guy on the end of the tool.        @ Ironhead is there a PDF file on this thread I can download I don't have time to go back and read the whole thred my time is getting real limited .
