Welding circuit resistance

measurement

Use the welding circuit resistance measurement function to
compensate for the voltage drop e.g. with long hose packs.
If you are working to the welding instruc-
i i
tions in our EN1090 WPS Booklet you will
not be able to use this function. The voltage
values displayed do not apply in this case.

area, applying gentle pressure
9 If the measurement is correct, the measured value is

measurement
 Use the rotary knob A41 to select the CLO code.
 Use the rotary knob A44 to select the CLC code.
 Confirm by pressing the Save button A14.
We recommend that you take measurements
i i
at various points in the seam area in order to
exclude the possibility of measuring errors.

NFC Functions

NFC cards can be read in using the NFC read area.
The following functions are available.
– Read-in/installation of welding processes, welding
programmes, special programmes (upgrades) or
credit cards
– Log-in of users with different user rights
– Read-in of jobs (all parameter settings for a welding
process/operating mode)
12.1 Installation of upgrade or credit cards
without TAN
Upgrade or credit cards are NFC cards which are cancelled by
an upgrade operation. Such a card may contain one or more
credit values. Each upgrade or each application cancels one
credit.
 Hold the NFC card against the NFC read area A43.
9 The code "Acc" appears in the left-hand 7-segment display
A4.
9 The number of credits appears in the right-hand 7-seg-
ment display A12 (e.g. "001" for upgrade).
‰ The operation can be cancelled by pressing the Exit but-
ton A2.
 Press the Save button A14 to confirm the operation.
9 The upgrade or credit is installed on the device. The instal-
lation is displayed by a rotating chaser light in the right-
hand 7-segment display A12.
If the NFC card is removed too early from the
i i
NFC read area A43, then the installation can-
not be completed correctly. In this case, the
chaser light is still displayed and the NFC card
is blocked for other devices.
 Hold the NFC card against the NFC read area A43 once
again in order to complete the installation.
If the installation of a credit card has not been
i i
completed, the affected device is no longer
available. This means that the blocked NFC
card can be unlocked again on another device.
However, in so doing, the affected (possibly in-
correctly installed) credit is cancelled.
