Reading The Fitting Code With A Handheld Scanner; Starting The Welding Process; Welding Process - Hürner HST 300 Junior+ 2.0 Manuel Utilisateur

When the fitting is connected, the "No Contact" message
(see Display 2) disappears.
5.3 Reading the Fitting Code with a Handheld
Scanner
Only the bar code on the tag sticking on the fitting to be
welded may be used. It is not acceptable to read the fitting
code tag of a fitting of a different kind if the intended
one is damaged or unreadable.
Read the fitting code by holding the scanner in front of
the bar code at a distance of 5 to 10 cm (2 to 4 inches),
where the red line indicates the reading area. Then push
the reading button. If the data are correctly read, the weld-
ing unit confirms this by an audible signal and displays the
decoded data on the screen (see Display 3).
The displayed values are the nominal welding
parameters contained in the fitting bar code or
computed based on these data. They are displayed
Info
before the actual resistance of the electrofusion
fitting is measured. This means that even when
the showing ohm value is o.k., a resistance error
may still be detected (see Sect. 7.2). Only when
the welding process starts, the display shows the
actual, measured welding parameters.
The "Start ?" message means that the unit is ready to start
the welding process. Check the read data and if you see
that they are erroneous, delete them by pressing the STOP/
RESET key. The read data are also deleted if the welding
unit is disconnected from the fitting.

5.4 Starting the Welding Process

After reading or entering the fitting code, the welding
process can be started using the START/SET key, when the
"Start ?" message is displayed and there is no indication
of a problem.
Pressing the START/SET key will trigger a confirmation mes-
sage "Pipe treated?," which in turn requires a confirmation
with the START/SET key to start the welding proper.

5.5 Welding Process

The welding process is monitored for its entire duration
applying the welding parameters contained in the fitting
code. The welding voltage, the resistance, and the weld-
ing current are displayed in the lower line of the screen.
