Q: How to change the plasma machine  power source , We require the wiring color code for CNC interface plug Example , arc + arc - ,  ok to move , start 

A: The ARC+ is red, and ARC- is black.
To identify the other four wires.
There are two ways:
1. In AUTO mode, press IGNITING or CUTOXY, then use a multi meter to measure which two wires of these four are short circuited, these two wires will be START wires.
2. The other way is, go to DIAGNOSE in main menu, short circuit any two wires of these four, if the DLZ in INPUT becomes 1, which means these two wires are FINISH wires.
