1.7 Other descriptions
Ignition tip The power unit NOMARK 65/99 and connected stud welding gun work by
the tip ignition welding method.
In order to ignite an arc and therefore to generate a weld pool,
every stud must have an ignition tip.
Fan To avoid unnecessary soiling, the fan is only switched on when a
high temperature is reached.
Inert gas Inert gas is seldom used in tip ignition welding because the short
welding time gives little time for oxidation.
1.8 Welding elements (studs)
Depending on how the welding gun is equipped, threaded studs,
internal thread bushes and pins (in accordance with DIN 32 501)
of various sizes and materials can be welded if they have an ignition tip.
Fig. 1 - 9 Examples of different types of welding elements
The following conditions must be observed:
• The diameter of the welding element must be <= 10.
• Length of welding studs : from 6 to 40 mm with standard components.
For studs longer than 40 mm, an intermediate ring must be used.
• Length of welding pins : from 6 to 100 mm with standard components.
• A suitable chuck must be selected for every welding element.
