Principles of Operation
The HST 300 Print 450 allows welding electrofusion fittings
that feature a bar code. Every fitting is provided with a tag
with one or two bar codes on it. The structure of this code
is internationally standardized. The first code, encoding
the data on proper welding, complies with ISO 13950, the
second code, if present, encoding the component trace-
ability data, complies with ISO 12176.
The welding parameters can also be entered manually. The
microprocessor-controlled HST 300 Print 450 Welding Unit
• controls and monitors the welding process in a fully
automated fashion,
• determines welding duration depending on ambient
temperature,
• shows all information on the display in plain text.
All data that are relevant for the weld or for traceability
are saved to the internal memory and can be sent to a
USB stick.
