intro:HOMEMADE PLASMA CUTTER

I Have built a homemade plasma cutter for my shop and now you can.

Check out all my pictures and videos and start building one for your shop right now.

First things first.

Like all welding equipment it can kill you if you don't pay attention to what you are doing, so be careful and double check everything, then do it again.

I am not responsible for any injuriesor accidents that may happen.

You can get most of your parts for free or very cheap off of old cars, stoves, furnaces,microwaves, dryers or any appliance that you have access too. I'm not saying to use your ladies things, if you do and you get caught, I'm looking the other way but will say a prayer for you.

Turn on your speakers and watch my 1 minute video of my cutter melting steel like butter while listening to mission impossible tune.

step 1:tools I used to make it.

Here is the tools I used to make it.

Now the stand I made it on was welded but you can put all this in a wood box or even plastic if you dont have a welder.

1. flaring tool for making head connection.

2. Drill driver.

3. screw driver flat tip and slotted.

4. 1/4 nut driver.

5. 6 inch Cresent wrenches.

6. diaganol cutters.

7. lug crimpers from auto zone.

8. wire strippers.

9. zip ties 8 inch.

10. blue spade terminals, yellow rings and female terminals.

11. sticky feet to anchor the wires to board.

12. circular saw.

13. tefplon tape for air fittings.

step 2:How a Plasma Cutter Works

How the Plasma Cutter works

The Plasma cutter uses two things, Air and Electricity.

First the plasanator uses between 30 to 35 psi of compressed air.

The air flows into the head and around the electrode through tiny holes in the swirl ring which capture and spin the air in a high speed vortex.

Then the arc start circuit triggers and arc within this vortex and ionizes the air making it conductive, once this happens you now have a electricl short from the electrode to the work piece.

Then since you have this short, the main arc current is drawn from your DC circuit.

The amount of current drawn is determined by your load coils resistance, and then you get a large arc fire with a kick of super sonic air blast which is converted to plasma, the fourth state of matter.

This plasma is about 30,000 degrees F, hotter than the surface of the sun, and this is what blows holes in your steel like butter.

I hope this helps.. Joe

step 6:Instruction Notes

Ok, Some Notes:

Hopefully who ever you are that is looking this over, has some electrical knowledge of sorts.

At least be able to wire a switch so you can understand what s going on here.

First off, the circuit breaker on my board is something I had, to dress it up some and you don t need this type of breaker.

If you want, just use the breaker in the parts list for your fusebox, which you might already be equipped with.

The ground doesn t need to be ran through a fuse but you will need it connected to your board.

That s another thing, connections, you can save a lot of money by just using old ? inch bolts with two nuts on them for wire main connections or any lead connection you come across, I did in the beginning.

I have a picture for you to look at called terminal to show what I mean.

Also you can save half the cost if you would just look around for some of these parts in your own area.

An old stove, (coils) old microwave/oven combo (heavy-duty power cord wire for main leads or dc side of board), old 12 volt charger for non-working cordless drill (12 volt transformer).

Do you have an old car? Or can you get to a junkyard? (Coil, wire for coil, GM control module, Spark plug.

If you just take your time you could find 80 percent of this stuff just like I did.

Now I m just saying you could find this stuff but I don t recommend building this at all, it s for (EDUCATIONAL PURPOSES ONLY) and I m not responsible for anyone that gets hurt trying to build this.

Now the fittings you need to hook the plasma head to the filter is something you will have to put together (IN YOUR MIND, NOT FOR REAL) because what ever head you may use can be different from mine.

If you come across part say like the contactor switch, you find one cheaper but the coil voltage is 24 volts rather than 120.

No problem just tap into the 24 volt system and run that through the house switch rather than the 220, just email me with questions if you need to.

Here s a big one, when I get done cutting my capacitors still are holding a charge even when I disconnect the power, I just take a large bleeder resistor or have used also any old choke coil.

Touch it across the negative and positive wires coming off the caps don t worry about me it doesn t make a boom like you think.

Now my rig you see was just for test purposes and to make it easy to change parts easily and quickly if I needed to.

I plan on mounting all my parts in a nice cabinet probably wood construction and put some wheels to move around a lot easier.

Hers something, most of the china torches main lead (electrode lead) is ran through the air hose, so the connection nut is your electrode or negative connection.

This means that you would have to connect the electrode cable to the air filter frame.

It s a good thing your not gonna build this because it is not an isolated circuit like if it had a transformer so one would need to be careful around this unit.

That s why I would mount in wood case instead of metal.

About the computer fan, this is to cool the main bridge but it does n t have to be 120 volt.

If you have a 24 volt ac fan then just hook to 24 volt side instead of 120 and when breaker is on so will be fan.

When mounting the control module to a metal platt form don t foreget to put the grease that comes with it to help cool it although it never gets hot for me. Now that s what I would do if this was for real and not just (Educational) if you know what I mean?

The way I would do this project is start with page 1 and complete it then so on till I m done.

step 7:Time for lots of pictures, hold on to your seats.

Now you get tons of pictures and I will put a couple of videos on the end of this thing.

You have your work cut out for you but its really easier than it looks just follow these first diagrams one by one and you will be done in a flash.

Now here is a bunch of real pictures and pay attention to the ones about connecting your plasma head its very imprtant.

step 9:More Pictures to come Here are some more, don't go any place.

step 10: And some more

Oh yea, I said more.

step 11:My Friend George Muscotts Own (Warp Drive) cutter video

Here is a friends cutter he made with my plans and he named his (The Warp Drive).

I figured you wanted a break and the next video is of the plasanator on its test stand getting a good look at the parts in place. step 12:Just looking around at the (PLASANATOR)

heres a video of the plasanator on its test stand for you to look at.

Enjoy my friends and have fun and be safe. Joe

step 13:New One On The Way

Here are some pictures of a not yet finished one using dc relays instead of ac relays.

Circuitry the same except there is no breaker on board and dc relays. Enjoy
