1 Important Safety Precautions
1 Important Safety Precautions
The target group for this manual are qualied personnel who in view of their technical 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 extensive material damage.

1 Important Safety Precautions
Life-threatening danger for wearers of active implanted cardiac
devices
Never operate the stud welding machine if you wear a heart pace-
maker or implanted debrillator.
In this case, never remain in the vicinity of the stud welding machine
during welding.
Never operate the stud welding machine if persons with heart pace-
makers or implanted debrillators are in the vicinity.
Strong electromagnetic elds are produced in the vicinity of the stud
welding machine during welding. These elds could impact the function of heart pacemakers or implanted debrillators.
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 particulates.
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.

1 Important Safety Precautions
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 light 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.

tage into direct voltage
Stud feeder: Device for automatic feeding of welding elements
Stud welding gun: Device for welding of welding elements
Stud welding machine: Stud welding unit including stud welding gun
Stud welding unit: Device for provision of the electrical energy for
stud welding
Thyristor: Electronic component for contact-free switching of
high currents; switching takes place via the control
input
Welding element: Component such as stud or pin that is welded to
the workpiece
Welding parameters: Mechanical and electrical settings at the stud wel-
ding gun and at the stud welding unit (e.g. spring
force, charging voltage)
Workpiece: Components such as sheet metal or tubes to which
the welding elements are to be fastened

6 Intended Use
6 Intended Use
Our stud welding units are designed and built exclusively for industrial use. Nonindustrial use is expressly forbidden due to the lack of know-how about the welding
technology employed and the applicable standards.
The stud welding unit is intended exclusively for stud welding of standardised welding elements. Any other use will result in the desired strength of the welded joint
being reduced.
This stud welding unit can only be used with the HBS stud welding guns C 08 and
CA 08.
The intended use also implies observance of the stud welding gun operating manual
and compliance with the intervals and conditions for inspection and maintenance of
the stud welding unit and the components employed.
Always check the operating manual of your stud welding gun whether it may be
used with this stud welding unit.
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 gun for
detailed information on which welding elements may be used.

8 Components of the Stud Welding Unit
8 Components of the Stud Welding Unit
8.1 Main Assemblies
1- Charging device A - Primary supply
2 - Control B - Welding circuit
3 - Welding capacitors
4 - Welding thyristor
The mains alternating voltage is converted to direct voltage in the charging de-
vice (1). Charging of the welding capacitors (3) is performed with the charging
device and is fully adjustable. The welding capacitors store the energy required for
the welding process. The quantity of energy is dened by the operator via the charging voltage.
The welding thyristor (4) releases the charging voltage.
The charging process and the welding process are controlled by the control sys-
tem (2).
The negative pole of the capacitor is connected to the welding gun. The positive
pole is usually connected to the workpiece via vice grips.
The type plate is located on the backside of the stud welding unit.
