Gas pressure indicators
System status icons
Fault codes and icons
In manual mode, the gas pressure is displayed in measurements of bar and psi. The gas pressure bar is also a visual
indicator of the gas pressure.
Gas pressure bar
– When the arrow is centered in the vertical bar (the reference pressure of the
automatic pressure setting), the gas pressure is set to the preset (factory-defined) value. If the pressure is
higher than the preset value, the arrow appears above the mid-point of the bar. If the pressure is lower
than the preset value, the arrow appears below the mid-point of the bar.
In automatic mode, the power supply adjusts the pressure to the preset
value. You can use manual mode to adjust the pressure to satisfy the
needs of a particular cutting job. See
Manually adjusting the gas pressure
The screen displays icons to indicate the system’s status.
Torch started
– Indicates that the torch has received a start signal.
Torch is cutting
– Indicates that the cutting arc has transferred to the metal, and the torch is cutting.
Remote control
– Indicates that a remote control or CNC is controlling the power supply using serial
communications. All local controls are disabled.
Electrode end-of-life detection manually disabled
– Indicates that the electrode end-of-life
detection feature is manually disabled.
When a power supply or torch fault occurs, the system displays a fault code in the lower-left corner of the status screen
and displays a corresponding fault icon above the code.
Fault code
– The first digit is always zero. The other two digits identify the problem. Fault code
information is included later in this manual.
Only one fault code is displayed. If more than one fault occurs at the
same time, only the fault code with the highest priority is displayed.
Fault icon
– The fault icons that appear on the left side of the status screen are described below. A
fault code also appears to identify the fault. Refer to the troubleshooting information later in this manual.
Warning
– The system continues to run.
