I'm getting sick of the inconsistency on thin sheet of my floating head on my table. I'm pretty sure the Trafimet S75 torch does not have OHMIC ability so I'm wondering if my idea willwork.
I want to surround my torch with a light spring. Run the 24V- to this spring (insulated from torch housing) then continue the 24v- via a clamp on the plate. This will go to the Neg side of a relay. When the spring meets the plate it will trigger the relay sending the signal to my Break out board. I will have the torch on relay open the 24v- so that it cannot be damaged while cutting (not sure if it will)
Quick paint Diagram (note sping will be around torch and adjustable to be a hair lower then the torch):

Only thing I can think of is that on more detailed cuts the diameter of the spring may miss the plate. I do play on keeping the floating head as a backup.
Thoughts?
