Arcfony plasma cutter 53pro

in the manual/display there is a adjustment in seconds for the pilot arc from 3-15 seconds, what does this adjustment do? there is also a post air adjustment from 2-15 seconds . where should these be adjusted for the arc droid?

pilot arc from 3-15 seconds = How long to keep arc on when no metal is detected to cut - 3 seconds is fine

post air adjustment from 2-15 seconds = How long air passes through the torch to COOL IT DOWN when cutting is finished and arc has gone off. The longer the better esp when cutting 40 AMPS or more. minimum should be 5 seconds for any cut but if your have a small compressor tank you might want to reduce it to 3 and suffer faster wear on the plasma tips - heat makes them wear quicker

Thank you for explaining this
