Don't cut where it needs to be cut

Yes i have wires hooked to pins 3&4 on the CNC connector
can i plug 3 and 4 together to see if it will start

I can’t hear the relay clicking. The torch is fire when i hook 3 and 4 together

If the relay doesn’t click, when you press the manual torch fire button, the relay is probably damaged. Submit a support request to Langmuir support.
