10.0 SYSTEM OPERATION

(see Figure 4)
1. The CD-212 is designed for simple, yet precise operation.
2. It has an "ON-OFF" rocker switch/indicator light (1) and a variable voltage control dial (2) on
the front panel.
3. Before turning the unit "ON", the voltage control knob (2) should be turned counter-clockwise
to the lowest setting.
4. With all cables connected, turn the unit on by putting the rocker switch (1) in the "ON" posi-
tion. The integral indicator light (1) will turn on.

Setting the Weld Voltage/Capacitance
Slowly turn the voltage control knob
clockwise to increase the weld voltage until the
indicator knob is pointing at the appropriate
number for the particular stud size that you are
welding. (See the set up information chart,
Below).
NOTE:
Once the voltage control knob is set to
a higher setting, turning it counter-clockwise
will NOT reduce the voltage on the capacitor
bank, until the toggle switch (1) is turned
"OFF" (for approximately 10 seconds).
The settings are marked with the volt-
ages corresponding to various stud sizes. The
approximate voltages for each stud size is as
follows:
45 VDC
45-80 VDC
80-120 VDC
120-160 VDC
160-190 VDC
200VDC
