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 aect 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 equipment, 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 oers 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.

10 Preparing the Stud Welding Gun
10 Preparing the Stud Welding Gun
Prepare the stud welding gun by
– adjusting the chuck
– mounting the chuck
– adjusting the spring force.
Do not connect the gun to the stud welding unit until it has been prepared.
In this way you can avoid any unintentional starting of the welding
process.
10.1 Adjusting the Chuck
Select a chuck suitable for your welding element.

10 Preparing the Stud Welding Gun
Stick the welding element into the chuck.
1
2
An adjustable stop pin (1) is located in the chuck.
Disconnect the lock nut (2).
Rotate the stop pin in the chuck so that
– for welding elements up to 20 mm long,
the non-threaded part is in the chuck.
– for welding elements over 20 mm long, the
non-threaded part sticks out of the chuck.
For welding elements with internal threads or chucks for internal
threaded studs, a special stop pin accessory for internal threads can
be delivered.
Adjust the stop pin so that the overall measurement
value from the top of the lock nut to the bottom of the
welding element is between 50 and 51 mm.
Screw the lock nut back on.
Carefully retighten the chuck on the four ns with pliers
at regular intervals.
This ensures good current conduction. This prevents pre-
mature wear due to spark erosion.
