how to makeTHCAD10 work with pilot arc plasma

oh yeah, i meant i'll make it like the 1st picture, good to point it out

if i have time i'll give a try this afternoon

After digging in the HAL METER signals in found the PLASMAC:ARC-OK-OUT
So i added in machine_connections.HAL
"net plasmac:arc-ok-out => hm2_7i96.0.ssr.00.out-01"

My relay is getting activated only when i get the arc ok green light.
Time to connect it to the pilot arc return !!

THC works !!!

Some minor problems still, but hte THC works now, i can cut on a 45deg angle no problem

Minor porblems are :
1_ need to add a delay between the ARC OK OUT signal and the ativation of the output SSR on the 7i96 so the arc has time to "dwell"
2_ cant use a "not" for piloting the SSR output so had use a mickey mouse combination of relays to make an NC relay (as i only have NO relays), but now i have big ass relay for the pilot arc.

Nice !

I'm even thinking of using the pilot return from the torch as a ohmic sensor now that it can be disconnected !

Btw i used a motorbike starter relay, it's beefy enough to handle the amps i think.

Having troubles setting up the correct timer for the torch to initiate the arc, so i am activting the relay to cut the pilot arc by using

net plasmac:thc-active => hm2_7i96.0.ssr.00.out-01

and it works perfect as the THC activation delay is user defined
