Appropriate dwell time.
Permalink  
 


I need to cut parts out of a plate of 1 5/8 inch mild steel.  I have never attempted to cut anything this thick, and was looking for information on the appropriate dwell time for something of this thickness.  At no point will I be able to start "off the part" and lead into the part.  I must pierce the material every time.  So far I am set up for Line lead in (at .200 long) and arc out (at .150 long).  What should be my "abrasive on" dwell time for this?  Also I have an 87k pump.

Went ahead and did it, took 103 seconds to "break though" at 87k.
