4.2 Chuck preparation
The Chuck is selected in dependence on the welding
element
(welding stud). The extent of delivery of the stud welding
system
contains chucks from M3 to M8.
The suitable Chuck must then be adjusted to the length of
the
welding element
.
Note: Chucksare wearing parts and should therefore
always be
kept in stock and ordered in time (see chapter 5.10).
Procedure
1. Select a Chuck fitting the diameter and form of the
welding element.
2. Depending on the length of the welding element, fit the
striking
pin in the Chuck as follows:
a) Welding elements up to 20 mm in length:
The unthreaded part of the striking pin is located
inside the chuck.
b) Welding elements from 20 to 40 mm in length:
The unthreaded part of the striking pin is located
outside the chuck.
c) Welding elements over 40 mm in length:
An intermediate ring (accessory part) is additionally
required (see
chapter 1.19 and chapter 5.4).
3. Equip the Chuck with the welding element.
4. Turn the striking pin until the distance between locknut
and stud face is:
when using the C0: 51 mm (to max. 53 mm)
.
Note: Add 12.5 mm when using a Chuck extension!
5. Warning: Switch off the power unit before inserting the
Chuck (to rule out any eventualities).
