Feathertouch & torch volts

Postby djreiswig » Sun Aug 27, 2017 2:55 pm

I installed the FeatherTouch ohmic sensor on my table and now my torch volts don't go to zero when I'm not cutting. It fluctuates from 0 to 1 or 2 volts while it is sitting. If I disconnect the wire from the shield it will go to zero and stay there. I don't think it is affecting anything as far as cutting goes, I just think it is weird. Is the cutter getting feedback from the ohmic voltage and causing this? Is there something I need to re-calibrate?
