9.2 Correctly charging the batteries
Make sure that the batteries are fully charged prior to the initial use.
The battery recharger has a display showing the charge condition of the inserted
battery (see Fig. 7).
Overheating or damage to the battery: The left display of the
battery recharger (Fig. 7) indicates if the battery is overheated
or damaged. If the display comes on red, immediately remove
the battery from the battery recharger to avoid any further
damage or chemical leakage. Do not use a defective battery.
Dispose of the battery according to all applicable rules and
regulations (see chapter 12).

battery recharger
Make sure that the battery is only charged as long as necessary.
This prevents damage and reduction to the charge capacity.
9.3 Preparing the device for use
To use the device for igniting a weld portion in a crucible, the electrodes must be
inserted into the electrode guide at the front until they snap into place and are
held firmly. The well charged battery is latched onto the device.
The charge condition of the battery shows on the display
(under BAT LED) after the device is switched on (see related
table in chapter 8.3).
