Displaying Plasma System Resistance r
General Measuring the plasma system resistance provides information on the total resist-
ance of the plasma torch hosepack and the plasma torch.
For example, if the plasma system resistance increases after the plasma torch is
replaced, the following components may be faulty:
- Plasma torch hosepack
- Plasma torch
- Plasma torch wearing parts
- Current sockets
The plasma system resistance is displayed on the right digital display after meas-
uring.
r ... Plasma system resistance (in mOhm)

Resistance r
1
In Gas Setup, set the GAS parameter to "OFF"
2
Establish contact between the electrode and the plasma nozzle
3
Access the 2nd level Setup menu
4
Use the left or right parameter selection button to select the "r" parameter
NOTE!
Ensure that there is contact between the electrode and the plasma nozzle
with new wearing parts.
The cooling unit is deactivated during the measurement.
5
Briefly press the gas-test button
The plasma system resistance is calculated, the right digital display shows
"run" during the measurement
The measurement is finished when the right digital display shows the plasma
system resistance (e.g. 11.4 milliohm)
6
In the gas setup menu, set the GAS parameter to the desired value
