A blow forward plasma torch starts the arc by blowing apart the touching electrodes then the arc is transfered to the work plate.
This torch head requires 50 amps of power and will cut 1 inch steel. To add this to the home made plasma cutter you will need to add a second resistor in parallel.
Really interesting concepts and design. Again, thanks for the AWESOME video posts.
