5.10 Welding Elements
The stud welding unit must be suitable for welding the welding elements to be used.
Observe the instructions in the operating manuals.
Welding elements manufactured with the cold formed process have a flange and an
ignition tip (see actual standards in the appendix). During welding the flange prevents
the deviation of the arc to the cylindric part of the welding elements along with an
increased welding area.
We recommend the following standard welding elements (see appendix).
Use only welding elements of the same lot. Take particular care
not to mix-up different lots. Slightest variations in geometry of
the welding elements, especially of the ignition tip, require
modified settings of the welding process.
