Principles of Operation
The HST 300 Monofuse 2.0 Welding Unit allows jointing with fittings
of the Fusamatic contact system, with which the specific welding time
is determined based on the fitting itself.
The microprocessor-controlled HST 300 Monofuse 2.0 monitors the
characteristics of its power supply and the ambient conditions continu-
ously. If one of the parameters is out of tolerance, welding is aborted
or cannot be started.
