10. OPERATION
(Continued)
10.2.2 Key Lock
Key lock is a function to prevent the welding conditions from being changed by accidentally
operating keys and knobs on the front panel. Only the keys and parameter adjusting knob
which are used for changing each parameters and modes can be protected. However, you
can still use DISPLAY CHANGE key[7], ARC CONTROL key[8] to confirm setting values
when in a Key Lock state.
This LED blinks
when in a KEY
LOCK state.
Holding down ENTER key[14] brings the key-lock condition. While keys
are locked, the lock lamp (located at the upper of the Enter key) blinks.
The key lock can be cancelled by holding down ENTER key [14] for a
while again. The key lock is not cancelled by starting the machine up
again.
NOTE: Even in a key lock state, GAS CHECK, INCHING, and JOB MEMORY function can
be activated.
10.2.3 Password Lock Function
The primary purpose of the Key lock is to avoid changing welding conditions accidentally. In
other words, everybody can un-lock it easily. On the other hand, this Key Lock with the
Password make possible to avoid any change by those who does not know the password.
The basic operation is the same as the standard Key Lock. If the password has been set, the
welding power source will ask the password to un-lock. Until you enter the correct password,
the welding power source never un-lock itself.
NOTE: If the Password Lock is activated, entering the correct password is the only way
to un-lock the welding power source. Neither Initialize process nor power-on
reset can un-lock it. If you want to change the password, you have to enter the
current password first. Therefore, please manage the password well and never
forget it.
In the password setting or entering mode, the welding power source will not be
available for welding. (Power source disregards for the torch switch signal).
[1] How to set password
(1)
Turn off the welding power source at once. After pressing the ENTER key [14] and turning
on the power switch simultaneously, the digital meters on the front panel will display “PAS
PAS” for 2 seconds before switching to the password setting mode.
If no password was set, the left digital meter will display “Loc” constantly (without blinking),
and then you can go straight to step (2) to set a new password.
If a password was set, the left digital meter will blink “Loc”, and then you can cancel the old
password first according to the steps (2) and (3) in section [2] below before going to step
(2) here to set a new password.
