10.3 Setting the Welding Parameters
The insertion depth, lift and spring force are, among others, dependent on the work-
piece and welding elements used and their diameters.
The specications in the following table are guidelines.
 Select the applicable parameters for insertion depth, lift and spring force for your
workpiece.
