** In most cases capacitor discharge welds do not have a significant nugget.
*** For non-Miyachi Unitek weld heads.
A certain amount of experimentation is necessary to achieve the proper welding force setting for a
specific application. The following are some general rules to make quality welds:
a. Larger parts require higher force.
b. Larger diameter electrode faces require higher force.
c. Higher electrode forces require higher weld currents (energy).
