I have an ez router 4x4 apc plasma machine i have no problems cutting .125 mat i'm trying to set up to cut .187 mat the machine has a miller spectrum 375 plasma torch that i'm using its not cutting all the way through the mat in spots and is leaving alot of slag when it does cut through, anyone have suggestions on amps ,tip volts, and speed i should be using thanks

Your user manual for the Miller Spectrum 375 should have charts listed to give you a basic guideline of input parameters needed to cut 3/16" plate. I don't know the exact model number you have (there are a few listed for the 375), but using page 21 in this user's manual: http://www.millerwelds.com/om/o225216g_mil.pdf

I come up with the following:

40 inches/minute @ 27 amps

or

26 inches/minute @ 20 amps
