Electrical tests
Insulation resist-
ance
-
Test voltage for insulation meas-
urement 500 V DC
-
Insulation resistance must be at
least 2.5 MΩ
-
Must be measured from the cur-
rent sockets to the tab on the cas-
ing (behind the control panel)
-
The lowest measured value must
be entered in the test record
1 Measuring device
2 Test piece
9 Instrument leads
IMPORTANT!
If no conductive connection exists between the welding current sockets during
the measurement, then the measurement must be performed on every current
socket.
Open circuit
voltage
-
Peak value measurement of open circuit voltage at the power source current
sockets
-
The measurement must be performed using the "Measuring circuit for U0
measurement"
-
The measurement must be performed in "Electrode" mode
-
The open circuit voltage may not exceed the value specified on the rating
plate for a power source supply at rated welding voltage
Performing the measurement
-
Connect the measuring circuit and the multimeter to the power source
-
Set the multimeter to DC voltage measurement and the measuring circuit to
UPeak
-
Briefly press the Reset button to discharge the capacitors
-
Adjust the potentiometer until the largest voltage value is shown
-
Enter the measured voltage value in the test record
