Replacing a WS2000 timer
If you have an existing installation with a WS2000 timer and a primary toroid, and you
are replacing that timer with a WS2003, then use the following procedure:
1.
Note the existing settings (weld program), measure the welding current with a meter, and note the
current measured by the WS2000.
2.
Fit the new timer (WS2003).
3.
Adjust the primary toroid calibration trimmer to fully anti-clockwise.
4.
Initialise the data in the WS2003.
5.
Set the toroid sensitivity to 1400mV/kA
6.
Set up the appropriate welding program, using the settings recorded in step 1, but using PHA mode.
7.
Weld – measure the current (x) with a meter, and (y) on the timer.
8.
Calculate x/y and enter this as the S/P ratio.
9.
Weld – the current (z) on the timer should agree with the meter.
10.
Enter z (the current value) into the current parameter in the timer program.
11.
Weld.
12.
Select CCR if required.
