5.9 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 arc getting to the cylindric part of the welding element and increases simultaneously
the 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.
