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
