Principles of Operation

The HST 300 Manual USB 2.0 allows welding fittings that require
welding voltages from 8 V to 48 V. Every fitting has its own proper
welding voltage and welding time. To properly joint with the fitting,
these data have to be entered manually.
The microprocessor-controlled welding unit controls and monitors the
welding process in a fully automated fashion. A sensor at the welding
cable senses the outside temperature and adjusts the welding time
to it automatically
All data that are relevant for the joint or for traceability are saved to
the internal memory and can be sent to a USB stick.
The unit monitors the characteristics of its power supply continuously.
If one of these is out of tolerance, welding is aborted or cannot be
started.
