STORED ENERGY RESISTANCE WELDING POWER SUPPLY

Press RUN if you do not want to save the changes. The RUN State will be re-entered and the changes
will be transferred to Schedule 0. These changes will remain as Schedule 0 only until the power is
switched to OFF since this information was not saved in permanent memory.
For example:
Use
SCHEDULE to select Schedule 1.
Press
1ST PULSE PROGRAM.
Now use ENERGY to select 86%.
Press RUN.
The change made to Schedule 1 has been transferred to Schedule 0 and the 125DP is in the RUN State,
ready to make a weld. Schedule 1 has remained unchanged.
Example continued:
Use SCHEDULE to select Schedule 1. Notice that the parameters for Schedule 1 are as
they were before the 86% Energy entered.
Press 1ST PULSE PROGRAM]. Use ENERGY to select 91%.
Press SAVE.
Since Schedule 1 was "saved," the %ENERGY for the 1st Pulse was changed to 91% and saved
in the 125DP's permanent memory.
Notice that the information was not transferred to Schedule 0 because RUN was not pressed.
Power Up Schedule
The last Schedule which was SAVED will be displayed EACH time the power supply is turned on.
NOTE: This feature can be used to selectively determine the Schedule displayed on power up. To start
the next day with the schedule currently in use:
Press
PROGRAM.
Press
SAVE.
The current Schedule is now the last schedule SAVED and will be displayed when the unit is switched
OFF and then ON.
Copying Information in Schedule 0 to another Schedule
Schedule 0 is unprotected, therefore it is assumed that it will be used to develop new weld schedules.
After the weld schedule is tested it can be copied, without re-keying, to another schedule and saved in
permanent memory
