a. Data Input
Input Error
Error while entering data with the cursor keys.
Code Error
Error while reading data from a bar code or an RFID card.
b. System and Conditions
System Error
The welding system has to be disconnected immediately from both
the power supply and the fitting. The auto-test has detected an
error in the system. The welder must no longer be operated and has
to be sent to an approved shop for check and repair.
