Deleting Data from Memory

The report data in memory can be deleted only after all welding reports
were transferred, which is indicated by the "Download completed"
message. When the storage media is unplugged, a "Delete Memory"
message appears. If the START/SET key is pressed at this point, a fur-
ther confirmation message "Delete Memory, sure?" is shown, which
has to be confirmed by pressing the START/SET key once again. Then,
the report data in memory are deleted.

Keeping Data in Memory

When the cable or storage media is unplugged, a "Delete Memory"
message is displayed. Press the STOP/RESET key to keep the current
report data in memory. They can then be printed off once again.
Make a habit of handling the internal storage as described
at the beginning of Sect. 5, to maintain data integrity and
avoid any inadvertent deletion of the reports in memory.

Service and Repair

As the product is used in applications sensitive to safety consider-
ations, it may be serviced and repaired — excepting the items specified
below — only on our premises or by partners who were specifically
trained and authorized by us. Thus, constantly high standards of op-
eration quality and safety are maintained.
Non-compliance with this provision will dispense the manu-
facturer from any warranty and liability claims for the product
and any consequential damage.
Important
Once a year, the welder has to be returned for preventative mainte-
nance.
• Prior to every welding operation, check the state of repair of the
wedge welder, in particular of its gear box.
• Before you store the wedge welder after the last welding of your
schedule, remove any plastic residues from the welding wedge
and the nip rollers; use an alcoholic cleaning agent if necessary.
Keep in mind that the welding wedge remains extremely
hot after the welding operation. Only switching it off at the
On/Off switch or the welding wedge switch will result in its
starting to cool down.
Caution
• Lubricate the gear box on a regular basis.
• Clean the wedge welder regularly, in particular when it is going
to be stored for a prolonged period of time.
