The welding unit can be configured to ask for the welder identification code before the fitting

code is entered. The display screen then shows the message “Enter Welder Code.” (Later this

screen can be accessed by a quick access routine; see Sect. 6.1.) The numeric code can be entered

either by reading it from a tag with the scanner or by using the п, р, с, т keys. Whether the

welder identification code has to be entered and if so, when or how often, is determined in the

“Settings” sub-menu of the configuration menu (see Sect. 10.1).
When the welder code is read from a bar code using the scanner, an

audible signal confirms this and the screen shows the read code and

switches to the next input display. When the code is entered

manually, it is saved by pressing the START/SET key. If the code

entered is not correct, a “Code Error” message appears; check the

sequence of numbers and correct as needed. If the code entered is

correct, it is saved to system memory and inserted into the welding

reports to be printed.
Only an ISO standard-compliant welder identification code is accepted by the unit. If the welder

code feature is disabled, the input screen for the welder code will not show.

contact. Use terminal adapters if needed. The contact surfaces of the

cable connection terminals or adapters and the fitting have to be

clean. Dirty terminals may lead to improper welding and also to

overheated and fused 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 welding 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. 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 Code” screen with

the ï arrow key (see Sect. 6.1). In this screen, the selection cursor can be moved using the ñ and

; the selection is made with the START/SET key.
