welding mode. It is possible to escape by turning on and 
pushing the SAVE button when escaping from the SAFE mode 
without changing the option of the SAFE mode.

To enter the SAFE, press the SAFE MODE
button of the panel. Continue to press the button 
until the meter displays the word “PAS”. The SAFE 
is waiting for the correct password code to be 
entered using the Control knob, and press the 
Forward button. It is possible to enter the SAFE 
mode if a correct code (350 by factory default) is 
input. This code insures that inadvertent access to 
the SAFE is not possible. A correct code will cause 
the 400MSTP display “1P0” (For 1phase) or 
“3P0” (For 3phase). 
 
 Access to the SAFE has now been established. 
The first two digits, reading left to right, is the 
1phase or 3phase. It is displayed, 1phase it "1Px", 
and 3phase it "3Px". The rightmost digit is an 
option number of the parameter that is currently 
being set. An explanation and description of this 
option can be found in the preceding table. The 
following three digits correspond to the parameter 
values. These digits will flash. 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Changed to the displayed parameter value can be 
made by turning the Control knob. 
 
To gain access to the next option number,
press the Forward and Back button. At each 
option proceed as described in the previous 
paragraph. 
 After all changes have been made to the SAFE, 
the SAVE button must be pressed in order to save 
the new parameters and restart the system. A 
successful saving of the information will be 
followed by the 400MSTP re-starting and entering 
into the “normal” weld mode. Failure to save will 
cause all changes to be lost. A power down prior 
to saving will also cause all changes made while 
in the SAFE to be lost.
