ESAB LHH-tester
The ESAB LHH-tester is a trigger pulse generator which generates trigger pulses at a frequency of 800 Hz +/- 1%. It is used for troubleshooting in the LHH welding rectifiers. No separate power source is required: the tester only has to be connected to the welding rectifier, replacing the printed circuit board K70.
The LHH-tester can be used to:
- Test the power unit of the LHH welding rectifier
- Check the secondary voltage phase position on the main transformer K1
- Measure the trigger pulse to thyristor K91.1
- Check the current transformer K42
- Check the pulsation voltage (ripple)
