Dear Sir

i need some help.

i purchased a CNC plasma table from a chinese manufacturer and and hypertherm Powermax 45 plasma machine.

my CNC table has only 4 wires to connect to the Plasma machine.
while the Hypertherm Plasma has 6 wires.

the chinese engineer says that 4 wires ( 2 arc start & 2 Arc voltages ) are sufficient for running the machine.

is he correct??


how can i find check whether the THC is working properly or not?
and can i run my machine without the THC?

how can i check the CNC Controller Signals?
