AUTO-CUT 300 XT
Manual 0-5261 APPENDIX A-5
5 OK to Move2 – Provides a second set of N.O. contacts that close when arc transfer is detected. Contacts are rated
for maximum of 24 VAC/DC @ 1A. Simplified CNC Circuit.
5 +10V @ 10ma. For Remote CC Pot – Previously CCM versions if one wanted to use a potentiometer for the Remote
Analog Current Control (CC) input an external 10 V supply was required for Pot High.. Now an isolated (from main
plasma circuits) 10V supply is provided. Recommended value of the pot is 5K or 10K.

Plasma Marking (input) --- Plasma marking is available only with Ultra-Cut XT systems with Auto Gas Box.
Corner Current Reduction (input) --- When activated, normally from a table controller’s corner or height control
inhibit signal, signaling that the cutting speed is being reduced to navigate a corner or small radius, the cutting
current is reduced at a fixed rate to a predetermined level to provide an improved cut at the lower speed.
Cut Expanded Metal (input) ---Normally the plasma supply is optimized for pierce cutting, high pierce height di-
rectly above the metal to be cut, short pilot time, etc. Activating this input adjusts the plasma supply to optimize
it’s parameters for cutting expanded metal, perforated metal, running edge starting, etc. Among other changes
the transfer height is reduced to same as cut height. In addition to activating the Cut Expanded Metal input CCM
switch SW1-1 should be turned on automatically restart the pilot and SW8-1 set on for longer pilot time.
Spare contacts --- These are not currently active but are reserved for possible future use.
