connection terminals. Protect the cable connectors against
getting dirty at all times. Terminals and push-on adapters
should be considered consumables and, therefore, have to
be checked before every welding operation and replaced
if damaged or dirty.
When the fitting is connected, instead of the "No Contact"
message (see Display 2) the number of the next welding
report appears, e.g., "Prot. No.: 0015."
5.4 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 4).
The displayed values are the nominal welding
parameters contained in the fitting bar code or
computed based on these data. They are displayed

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. 9.2). 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.

5.5 Direct Welding with the AutoWeld Feature

If two welding operations with electrofusion fittings with
the exact same welding parameters succeed each other, it
is not necessary to read a fitting bar code or enter welding
parameters manually. To start a welding operation that
is fully identical to the preceding one, it is sufficient to
use the AutoWeld feature, provided it was enabled in the
configuration menu (see Sect. 10.1). It is accessible from
thre quick selection screen opened from the "Enter Fitting
