1 Important Safety Precautions
1 Important Safety Precautions
The target group for this manual are qualied personnel who in view of their techni-
cal training, know-how and experience and knowledge of applicable regulations are
able to assess the work assigned to them and recognise potential hazards.
Danger from incorrect use
Use the stud welding machine only for the purpose described in this ma-
nual.
Otherwise you may endanger yourself or damage the stud welding machine.
You endanger yourself and others if you operate the stud welding machine
incorrectly or fail to observe the safety precautions and warnings. This can
lead to serious injury or extensive material damage.
Danger for unauthorised operating personnel
Work with the stud welding machine only when
– You are appropriately trained, instructed and authorised to do so, and
– You have read and completely understood this operating manual.
Never work with the stud welding machine when you are under the inu-
ence of
– Alcohol,
– Drugs or
– Medication.
Danger from unauthorised modications
Never modify the stud welding machine or parts thereof without obtaining
a clearance certicate from the manufacturer.
You will otherwise endanger yourself. This can lead to serious injury or ex-
tensive material damage.

1 Important Safety Precautions
Life-threatening danger for wearers of active implanted cardiac
devices
Danger for workers at particular risk within the meaning of the
EMF directive
Persons at particular risk within the meaning of the EMF directive are:
– Workers with active implanted medical devices
– Workers with passive implanted medical devices that contain metal
– Workers with medical devices worn on the body
– Pregnant workers.
Never operate the stud welding machine if you are among the group
of workers at particular risk within the meaning of the EMF directive.
In this case, never remain in the vicinity of the stud welding machine
during welding.
Never operate the stud welding machine if persons are located
nearby who are among the group of workers at particular risk within
the meaning of the EMF directive.
Strong electromagnetic elds are produced in the vicinity of the stud
welding machine during welding. These elds can adversely affect the
function of medical devices as well as the course of a pregnancy.
Danger from fumes and airborne particulates
Switch on the welding fume extractor at the place of work.
Ensure that the room is well ventilated.
Never weld in rooms with a ceiling height of less than 3 m.
Observe furthermore your working instructions and the accident
prevention regulations.
This will help to avoid health damage due to fumes and airborne parti-
culates.

1 Important Safety Precautions
Danger from glowing metal spatter (re hazard)
Glowing hot weld spatter and liquid splashes, ashes of light and a
loud bang > 90 dB (A) must be anticipated during stud welding.
Inform colleagues working in the immediate vicinity accordingly
before starting work.
Ensure that an approved re extinguisher is available at the work-
place.
Do not weld when wearing working clothes soiled with ammable
substances such as oil, grease, petroleum, etc.
Wear your proper protective clothing, such as:
– Protective gloves in accordance with the relevant standard,
– Non-ammable clothing,
– A protective apron over your clothing,
– Full-ear hearing protection in accordance with the relevant stan-
dard,
– A safety helmet when welding above your head,
– Safety shoes,
– Safety goggles with sight glass of protection level 2 in compli-
ance with the applicable standards and do not look directly into
the electric arc.
Remove all ammable materials and liquids from the vicinity of the
work area before starting welding.
Weld at a safe distance from ammable materials or liquids.
Select a safety distance large enough to ensure that no danger can
arise from weld spatter.
Protection of the stud welding unit
Protect the stud welding machine against the ingress of foreign
matter and liquids caused by cutting or grinding work in the vicinity
of your work area.
This will help to prolong the service life of your stud welding machine.

1 Important Safety Precautions
Safety notices in accordance with EMF directive 2013/35/EU
Currents owing through electrical conductors during stud welding cause electric
and magnetic elds that can occur, in particular, near the hand-held welding guns,
the welding arrangement (e.g., welding cables) and the welding power sources.
Due to the high currents, high EMF exposures may occur.
Danger for workers at particular risk within the meaning of the
EMF directive
Persons at particular risk within the meaning of the EMF directive are:
– Workers with active implanted medical devices
– Workers with passive implanted medical devices that contain metal
– Workers with medical devices worn on the body
– Pregnant workers.
Strong electromagnetic elds are produced in the vicinity of the stud
welding machine during welding.
To reduce the danger posed by electromagnetic elds, we recommend, among other
things, the following rules of conduct:
Lay all cables as close together as possible.
For proper bundling and safeguarding of the cables, HBS offers protective tubes in
various sizes.
Do not position yourself between the welding cables.
Only lay the cables to one side and position them as far as possible from the
operating personnel.
Do not loop the cables over your body, especially not at head level.
Completely unwind the welding cables.
Use the shortest possible welding cables.
Place portable welding power sources as far away as possible while welding.
If possible, do not operate welding power sources in the immediate vicinity of
other persons, do not sit directly next to the welding power source while working
and do not lean against it.
In addition to these safety notices, also observe your work instructions and acci-
dent prevention regulations.

6 Intended Use
6 Intended Use
Our stud welding unit are designed and built exclusively for industrial use. Nonindus-
trial use is expressly forbidden due to the lack of know-how about the welding tech-
nology employed and the applicable standards.
This automatic stud feeder (VBZ) is intended exclusively for stud welding of standar-
dised welding elements. Any other use will result in malfunction during the feeding of
the welding elements.
The stud welding units ARC 800-4, IT 1002-4, IT 1002-6, IT 50, IT 90, CDMi 2402,
CDMi 3202, CDi 1502-4, the welding gun PAH-1 or the welding heads KAH 412 and
KAH 412 LA may only be connected to this automatic stud feeder.
The intended use also implies observance of the operating manual on the stud wel-
ding unit, the welding gun or the welding head used and compliance with the inter-
vals and conditions for inspection and maintenance of the stud welding unit and the
components employed.
Always check with the operating manual of your stud welding unit and the used
components whether they may be used with this automatic stud feeder.
The stud welding unit must be suitable for welding the welding elements in use.
Welding elements manufactured with the cold formed process have a ange and an
ignition tip. During welding, the ange prevents the arc getting to the cylindric part of
the welding element and increases simultaneously the welding area.
Please refer to the operating manual of your stud welding unit for
detailed information on which welding elements may be used.

10 Preparing the Fully Automatic Stud Feeder (VBZ)
10.1 Adjusting the VBZ
Remove the cover on the separator cage.
Take care not to lose the o-ring (pos. 20), which is located between the cover and
separator cage.
Without the o-ring, feed problems will occur.
Loosen the screw (pos. 1) to swivel the feeding bowl (pos. 10).
Loosen the two screws (pos. 3); the separator (pos. 9) can then be adjusted in
the vertical direction with the screw (pos. 2).
Loosen the screws (pos. 4 and 5) to adjust the angle of inclination to the stud
outlet guide (pos. 11).
If the screws (pos. 6) are loosened, the entire unit (pos. 9) can be moved horizon-
tally and turned slightly.
