5. Use the SELECT push button to select PERCENT CURRENT.
6. Re-assert/update the programmed value by pressing ENTER or program the necessary
PERCENT CURRENT in the DATA display.
7. Put the control in OPERATE mode.
8. Make a weld. If necessary, adjust the CURRENT (repeat Steps 6, 7, and 8).
9. After the weld, the control will display a value of CURRENT.
10. Put the control in PROGRAM mode.
11. While in PERCENT CURRENT function, use the SCHEDULE push buttons to find

12. Program the appropriate value of HIGH and LOW limits if necessary. If these values
are left at

0000
00, control will use a limit of +10% for HIGH limit and -10% for LOW limit.
If FUNCTION indicator LEDs are set to display PERCENT CURRENT, the control will
show measured CURRENT after every weld. If the weld CURRENT is too low or too high,
the weld control will block further initiations. The Valve 3 output (410319 Firing Boards)
will turn on immediately upon a HIGH or LOW ERROR condition and remain on until the
Front Panel push buttons are used to acknowledge the error.
