Mechanized Cutting Mode
To place the SR-45i in the mechanized cutting mode, set the Mode Switch
thumbwheel to position number 2. The start signal initiates the following
sequence of events:
1.
Two-second gas preflow.
2.
Pilot arc initiation.
3.
Transferred arc establishes (cutting arc).
4.
X/Y machine motion signal enabled. Note that the machine motion
signal can be delayed for up to three seconds using the motion delay
potentiometer on the front panel.
Removal of the plasma start signal terminates cutting, disables the x/y machine
motion signal, and initiates gas postflow. Note: Loss of the cutting arc, even if
a plasma start signal is applied, deenergizes the SR-45i system, disables the x/y
machine motion signal, and initiates postflow of gas. Reapplying the plasma
start signal while in the gas postflow stage will initiate the cutting arc
immediately, without going through the gas preflow sequence.
