HOMEMADE plasma cutter
Your trying to control 300 volts dc at 10 to 30 AMPS. They are expensive
trying to keep from electrocuting the operator. Good luck Jim Vrzal wrote: Other than getting the halfnium-which should be readily available as a consumable- what would be so hard about building a plasma cutter?
