JOB MEMORY Function
The JOB MEMORY function enables welding conditions to be retrieved by storing the
welding conditions in memory inside power source and by reading out the stored data at
any time. The number of welding conditions that can be held in memory is up to100.
CAUTION
٨
The welding conditions (electronic data) stored by this function are susceptible to
occurrence of static electricity, impact, repair, etc., and there is a possibility that the
stored contents may be changed or lost. BE SURE TO MAKE A COPY FOR IMPORTANT
DATA.

Please note that we shall not assume any responsibility for any change or loss of
electronic data resulting from repair.
Once the machine enters the memory mode and read-out mode, only the SAVE, LOAD,
and ENTER keys can be operated. To exit the mode, press the LOAD key [19] if it is in
the memory mode, and the SAVE key [20] if in the read-out mode. Memory can be copied
to a different condition number after reading the welding conditions you want to copy.
NOTE: Even when welding conditions are read out while the analog remote control
is connected to the welding power source, the setting values preset with the
analog remote control are valid.
