(independent on possible power unit switched currents; limited by
the integrated 2.2 kOhm field discharge resistor).
When measuring currents, make sure that the minimum primary cur­
"
rent never drops below the respective primary current measuring
ranges indicated!
Otherwise, you will have to expect the following effects:
• Decreasing accuracy of current measurement
• Welding schedule is aborted in KSR mode with the fault message
"Schedule aborted, no current".
