Adjustment of Chuck
Various chucks for different stud diameters are available as unit accessories (see
appendix).
Select the chuck which fits the diameter of your welding element.
Put the welding element into the chuck. In the chuck, there is an adjustable stop
pin.
Loosen the retaining nut.
Twist the stop pin in the chuck in a way that
–
the unthreaded part of the pin is inside the chuck (for welding elements
up to 20 mm length),
–
the unthreaded part of the pin projects is out of the welding element
(for welding elements above 20 mm length).
As special accessory, a stop pin for welding elements with
internal thread is available.
Adjust the standard stop pin in such a way that an overall distance of 50 mm is
obtained between upper face of the retaining nut and bottom of the welding
element.
