!
Danger from electric current during maintenance and repair work
When working on live components, there is a danger to life from electric
current.
• Work on electric or electronic components may only be performed by
trained electrotechnical personnel of Soyer Bolzenschweißtechnik.
• Before performing any work on the stud welding device, the mains switch
of the device must be turned off and the mains plug must be disconnected.
• Before performing any work on the stud welding gun, the supply cables to

and their functionality has been checked.
DANGER
!
Danger of explosion from inappropriate operation sites in explosive
areas
The device is not designed for use in explosive areas.
• The device must not be installed and operated in explosive areas.
CAUTIONCAUTION
Danger of burns from hot surfaces
During the welding process, the workpieces and some parts of the welding
gun get so hot that touching them may cause burns.
• Always use personal protective equipment.
• Before working on hot parts of the device, check if they have cooled down.
• Do not hold the gun in the welding area.

14 Operating Instructions Soyer Bolzenschweißtechnik
2.3 Safety instructions regarding the working method
WARNINGWARNING
!
Hazards due to wrong working method
Not working according to the proper working method may lead to hazards for
the operating personnel and third parties.
• Ensure that the installation location for the stud welding device is ade-
quately stable and dry.
• Make sure that you do not upset the stud welding device or pull it down
from its position with the gun’s cables/lines.
• During mobile use in particular, make sure that you are standing in a stable
position during the welding process.
• Do not hold the workpiece to be welded in your hands during the welding
process. The workpiece must be securely fastened during the welding pro-
cess.
• Never wrap the gun’s cables/lines around any part of your body (e.g. arm),
as electric fields might be generated.
• Incorrect positioning or misadjustments of the gun may cause flashes of
light to be generated during the welding process. Do not look directly into
the flash of light.
• The gun carries out lifting movements during the welding process. Do not
hold the gun in the area of moving parts.

Important safety instructions
Operating Instructions Soyer Bolzenschweißtechnik 15
2.4 Electromagnetic fields - implants
Instructions for operating companies of stud welding devices in
accordance with DIN EN IEC 60974-9:2019-03 (extract):
Electric current flowing through a conductor causes locally limited electric and
magnetic fields (EMFs). All welders should apply the following procedures to
minimise the hazards which are related to the exposure to electric and magnetic
fields from the welding current circuit:
• Bundle the welding cables; if possible, secure them with a strap;
• Keep your body away from the welding current circuit as far as possible;
• Never wrap the welding cables around your body;
• Do not bring your body between the welding cables; keep both welding cables
on one side of your body; connect the return circuit to the workpiece as closely
as possible in the area in which the welding work is carried out;
• Do not work, sit or lean against something next to the welding power source;
• Do not weld when carrying the welding power source or wire feeder.
Electric and magnetic fields may interfere with portable medical devices and
implants. For people with portable medical devices and implants, protective
measures must be taken. These include, for example, access restrictions for
passers-by or individual risk assessments for welders. Risk assessments and
recommendations for people with medical devices and implants must be carried
out by a doctor.
DANGER
!
Danger from magnetic fields
In the area surrounding the device, strong magnetic fields which may influ-
ence medical auxiliary devices and therefore result in danger to life occur
during the welding process.
• Please observe the following instructions from the
DIN EN IEC 60974-9:2019-03 standard.

Important safety instructions
16 Operating Instructions Soyer Bolzenschweißtechnik
2.5 Personal protective equipment
It is recommended to wear personal protective equipment when working with the
stud welding device.
WARNINGWARNING
!
Danger from missing or incorrect personal protective equipment
Stud welding may lead to danger of burns, especially due to hot welding spat-
ters. Danger of blinding may also arise due to the occurrence of strong arcs.
• Always wear suitable and closed protective clothing.
• Type and extent of the required protective equipment depend on the
respective occurrence and the intensity of welding spatters, arcs and/or
noise. This varies depending on the basic material, stud material, stud size
and the required welding performance.
• Please observe the following instructions for protective equipment.
Recommended personal protective equipment
Safety goggles
Welding spatters and a flash occur during the welding
process. In order to protect your eyes, wear appropriate
safety goggles with side protection and a filter protector,
if necessary.
Protective gloves
During the welding process, the workpieces and compo-
nents of the welding gun get hot and welding spatters
occur. Wear appropriate, incombustible, heat-resistant
protective gloves.
Protective clothing
Welding spatters occur during the welding process. Wear
appropriate, incombustible and, if necessary, heat-resistant
protective clothing.
Safety footwear
Welding spatters occur during the welding process. Wear
appropriate, incombustible, heat-resistant safety footwear.
Hearing protection
Relatively loud welding noises may occur, depending on
the welding device and the welding application. In that
case, wear appropriate hearing protection.

Important safety instructions
Operating Instructions Soyer Bolzenschweißtechnik 17
