DTHC-SETUP/INSTALL MANUAL CandCNC

Kerf width: Sets the width offset used for inside or outside cuts. If you don’t know thevalue go back to you manual cut you made and measure the width.Feed Rate: The recommended feedrate for this tip. This is a default value and can bechanged when you build the cut file to match the material you are cutting.Preheat: Not used for plasmaPierce Delay: Zero for material thinner than .187. The pierce dely is a total of thissetting PLUS the time it takes the ARC OK to light PLUS the time it takes the torch toPLUNGE (at the Set rate) from Pierce Height to Cut Height. Excessive pierce delaycan result in voltage spikes that will “confuse” the DTHC and cause the TIP saver tolock on or the torch to plunge. Whatever the recommended pierce delay is on yourchart make sure you subtract the cycle time of the numbers above.Pierce Height: The recommended piece height for your plasma. Usually 2 times therecommended cut height on material thicker than .125 (3mm). This define how far thetorch will lift above the material after a touch off.Plunge rate: How fast the Z moves down from Pierce height to Cut height.Cut Height: The beginning cut height before the DTHC takes over after itsprogrammed delay (default 1 sec).Pause at end of cut: A pause after the torch is turned off from MACH to let the arc dieout and voltage to go to zero. Recommended ½ sec to 1 sec.PAGE 48
