Homemade Plasma Cutter Power Circuit. This vid shows all the needed connections for the power circuit of the plasma cutter. It must be wired this way. If you put the resistor on the torch and not on the work clamp then it WILL NOT WORK. The value of the inductance changes based on your capacitors and frequency, but I have found that most any inductor that does not have much resistance works fine. Use a MINIMUM of 1000uF photo flash capacitors; wire them in parallel. Solder all these connections and use more if you can. Do not hook the caps up backwards or they WILL explode. Remember this plasma cutter is not isolated from ground so YOU AND WHAT YOU CUT MUST BE ISOLATED FROM GROUND. There is almost no measurable voltage between ground and work or tip when on dry concrete, but be safe and wear rubber soled shoes and gloves anyway. The contactor disconnects the work clamp from the power supply when not cutting for added safety. I will be building a 110 volt version when I get the time. It will as safe as any other commercial product. This cutter however, is more like the older industrial robotic cutters.

Please note this is for informational purposes only! This device is not isolated from ground and in this current version could, under correct circumstances, cause a lethal shock. This device was tested on a dry concrete slab and show a open to ground voltage of 7.3 volts.

The writeup for that was on instructables.com, but it was removed due to the ground thing.

I really want to build one anyway.

Bad ass another thing I would like to build but ran out of garage space. ;D

[ADSR]

oh well. add another project to the list...

how much were those chinese plasma cutters that hmt guy was selling?
seems much better to just buy the chinese one for a little more money.

cool though

Fuck Phil Stubbs

probably just on the i hate phill stubbs bandwagon that got phill banned in the first place.

Yeah i love people who just peddle china shit.....

i would build one just so that people would have to pull my smoldering corpse off of it. if you  happened to touch that mess while your hood was still down, i would say your fucked. still, very cool, i want one.
