The hydrogen gas cutter uses only water and electricity to create an extremely hot flame that can be used for welding and cutting. i came up with the idea when my dad showed me a hydrogen gas generator that people commonly use for increasing there cars mileage. i though, why no put a braising tip on the end of a pipe connected to the gas chamber to create a flame.
i will take no responsibility for what you do with this invention, it can be dangerous if used incorrectly or irresponsibly
(i always wanted to do a disclaimer )
Step 1: What You Need
firstly, to build it this is what you
a fluid tight container (i made mine out of perspex)
if making a perspex container then a grinder or cutter of some sort
a power source (i used a car battery 12v 20amp hours, u could use a power supply, but straight 240/110v is to dangerous)
stainless/galvenised steel sheet
a vice (can be useful)
rubber hose/tube (i used 6mm)
copper tube (a little shorter than a hand) or braising head
hot glue gun (and glue of course)
spacers bout 1-2 mm (u can use washer, o-rings, wat ever)
soldering iron & solder
2 bolts/ thick screws
peach container, jam jar ect
now your ready to build!
start by building your cell
firstly if you havent got ur sheet metal already cut (i got mine easily at school) then cut it into equivelent sizes about the same as your hand, make an odd number of sheets. now, heat up your glue gun. place one piece of metal on the ground and place 2 spacers on the edges. now put glue near each 4 corners of the metal. place the next plate directly on top. once the glue is dry (less than 10 sec) pull out the spacers and repeat for next sheet of metal. when u get to the middle sheet slightly raise it so it will be easier to solder it later. when your done you'll hav a full cell. the more pieces of metal used the better the cell
Step 3: Building My Container.
firstly i marked out the perspex to suit my cell. then i cut the perspex with the angle grinder (i used the thinest blade i could find) . next i glued the container together with silicon glue (but leaving the lid off, make sure u do this). now i had a ready, sealed, container.
Step 4: Rigging the Lid
To start "rigging the lid" you need to drill six holes in the middle of the lid. the holes should be the thickness of your wires connecting the cell. now drill a hole the thickness of your rubber tube on the other side. on the other side glue your screws, bolds on as connectors for your leads to the battery. now solder on your wires to the cell. you will need 4 wires going to the two outside (2 per plate) and 2 to the middle plate, the outside ones are - and the inside one is +. now thread the wires through the holes to the outside of the cell. now solder the wires from the outside cell to one screw and the wires from the inside screw to the other, you have now rigged the lid :-)
Step 5: Attaching the Lid
firstly fill the container with water and add a spoon of baking soda, make sure you mix it up. line the top of the jar with silicon glue. now, using the wires to hold onto, lower the cell into the container. once its resting firmly press the lid on so when the glue dries it will seal. now seal the hole for the wires with silicon glue, your cell is actually ready for creating hydrogen now!
Step 6: Making Your Torch Head
before you do this you can just buy one and be done with it. but i made my own. i got a small length of copper and made a cut down the length (bout a 3cm cut) and roled the end into a nozzle. to make it air tight i sealed it with solder. try and get your tip really small. wet a small peice of sponge or use steel/brass wool and push it into the copper tube till its at the nozzle. now i just pushed the rubber tube into the back of it. done, its pretty easy.
Step 7: The Bubbler Burn Back Arrester
now, for safety matters, i made a bubbler burn back arrester. this is where you use the peach container (if u were wondering wat that was for) . fill it up with water, then you drill two holes in the lid. the tube from the gas generator goes right under water but the second tube is only there to collect the gas as it bubbles up. this way there is no chance of an explosion in the generator.
Step 8: Connect It All Up
connect the power source to the cell, the cell to the bubbler and the bubbler to the torch head, done!
Step 9: Light It and Use It
now take your matches and light the gas! now cut or weld what ever you want, it has a really hot flame! just make sure it is never producing gas without the gas being burned or you get a room filled with unburnt hydrogen. it is really is and cheap to make, most things you may already have and takes a weekend to assemble, so give it a try, you will like it. thanks for reading.
