We have a issue that the torch will not fire up every time when started. You see a spark shortly and that's it. When you release the start button the air is still flowing, and stops after a minute or so. Or just press the Start button again and it stops. We replaced all internals and checked the Cableling. No direct result, does anyone have an idea?
Now we try to interface it with a external start and instal a height controller. The external start is what I've read just a dry contact activate contact. But this doesn't do anything. When you check the schematics, the external connector is not wired parallel onto the torch contacts. Do I miss something?
thanks for reply.
