VOLTAGE SELECTION
Selecting the required weld voltage is achieved by turning the selector knob. The
voltage range is from 35VDC to 200VDC.
The voltage is determined by the diameter of the stud and the base material.
Approximate voltage staring points are listed below. Fine tuning the voltage to meet
your requirement for your specific application is recommended.
NOTE***when welding cupped‐head insulation pins, set the DC Voltage between 65
and 70 VDC to begin and increase as necessary. Adjust the spring pressure on the CD
gun between #1 and #3 as necessary.
