the transponder reader in the side panel of the system or by moving the
scanning pen in one consistent, swift motion across the code tag or hold-
ing 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 welding unit confirms
this by an audible signal and displays the decoded data on the screen
(see Display 10).
Info
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 shown ohm value is o.k., a resistance error may still be
detected (see Sect. 6.2). 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 de-
leted if the welding unit is disconnected from the electrofusion fitting.
4.6.4 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 weld-
ing 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. 4.4). It is accessible from thre quick selection screen
opened from the “Enter Fitting Code” screen with the
Õ
arrow key (see
Sect. 4.3). In this screen, the selection cursor can be moved using the
×
and
Ø
cursor keys the selection is made with the START/SET key.
Important
It is under the user’s responsibility to rely on the AutoWeld
feature only when the preceding and the planned welding op-
eration and electrofusion fitting are really fully identical to each
other. An erroneous or negligent use of the feature will result
in a poor, unstable joint.
4.6.5 Inserting the Components and the Balloon at the Start of the Welding Process
Info
After the fitting bar code was read, the input of all traceability
data related to the components themselves that were enabled
in the configuration menu (see Sect. 4.3, 4.4), is requested by
the system.
After reading or entering the fitting code, the welding process can be
started using the START/SET key, when the “Start ?” message is dis-
played and there is no indication of a problem.
The START/SET must not be pressed before both components have
been inserted into the electrofusion fitting — and the balloon as well for
an operation that should be beadless. While the components and, if so,
the balloon are being inserted, the thumb screw at the front of the fitting
clamp must not be fully tightened yet.
With common electrofusion fittings that feature a midline abutment on the
inside, the two components can be inserted into the e-fitting right away.
With specialty e-fittings that allow inside beadless welding, the process
has to be performed as explained in the following three paragraphs.
First pull the spacer bar away from its parking position on the right-hand
side in the bottom of the fitting clamp and install it inside the fitting in
