Principles of Operation

The HST 300 aquatherm 2.0 allows welding electrofusion fittings of
the supplier, aquatherm. The diameter of the fitting is selected manu-
ally. By entering the diameter, the operator provides the unit also with
the parameters it needs for properly welding that fitting.
The microprocessor-controlled HST 300 aquatherm 2.0 Welding Unit
• controls and monitors the welding process in a fully automated
fashion,
• determines welding duration depending on ambient tempera-
ture.
A temperature sensor located on the welding cable measures the
ambient temperature at regular intervals.
The output voltage at the welding cable is max. 48 volts transformed
by galvanic separation.
