Glossary
Arc:
Electrical discharge at its own between two electrodes
under sufficiently high current. Whitish light is emitted.
The arc generates very high temperatures.
Automatic welding head:
Device to weld welding elements
Capacitor:
A component which serves as storage of electrical
charge
Power unit:
Device to provide electrical energy for stud welding
Rectifier:
Electric component transforming alternating current
into direct current
Stud feeder:
Device for the automatic stud feeding of welding ele-
ments
Stud welding unit:
Power unit inclusive welding gun
Thyristor:
Electronic component, contactless switch, which will
let the current only pass through if a control pulse is
given to the gate (additional electrode)
Welding element:
A component, like a stud, bolt, pin, which is welded to
the work piece
Welding gun:
Device to weld welding elements
Welding parameters:
Various settings on the gun as well as on the power
unit. For example: duration and strength of current
during welding process, charging voltage, spring force
of the welding gun.
Work piece:
A component, like a sheet, tube, etc. to which the
welding element is fastened
