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
