3. SAFETY OF USE
ATTENTION! Read all safety warnings and all
instructions. Failure to follow the warnings and
instructions may result in an electric shock, fire and/
or serious injury or death.

3.1. GENERAL NOTES

• Take care of your own safety and the one of
third parties by reading and strictly following the
instructions, included in the operating manual of the
device.
• Only qualified and skilled personnel can be allowed to
start, operate, maintain and repair the machine.
Rev. 05.04.2022

3.2. PREPARATION OF WELDING WORK SITE
WELDING OPERATIONS
10 – 160 10 – 40
EXPLOSION!
• Strictly follow the occupational health and safety
124 31
regulations applicable to welding operations and
make sure to provide appropriate fire extinguishers
at the welding work site.
160 40
• Never carry out welding operations in flammable
places that pose the risk of material ignition.
- 4,5
• Never carry out welding operations in an atmosphere
containing flammable particles or vapours of
explosive substances.
- 80 – 200
• Remove all flammable materials within 12 meters
from the welding operations site and if removal is
1 – 4 1,2
not possible, cover flammable materials with fire
- 1 – 12
retardant covering.
• Use safety measures against sparks and glowing
metal particles.
Contact
• Make sure that sparks or hot metal splinters do
not penetrate through the slots or openings in the
- 2,5 / 5
coverings, shields or protective screens.

• Do not weld tanks or barrels that contain or have
contained flammable substances. Do not weld in the
≥85
vicinity of such containers and barrels.
• Do not weld pressure vessels, pipes of pressurised
installations or pressure trays.
F
• Always ensure adequate ventilation.
IP20S
• It is recommended to take a stable position prior to
welding.

3.3. PERSONAL PROTECTION EQUIPMENT
ELECTRIC ARC RADIATION CAN CAUSE DAMAGE TO
EYES AND SKIN!
• When welding, wear clean, oil stain free protective
clothing made of non-flammable and nonconductive
materials (leather, thick cotton), leather gloves, high
boots and protective hood.
• Before welding remove all flammable or explosive
items, such as propane butane lighters or matches.
• Use facial protection (helmet or shield) and eye
protection, with a filter featuring a shade level
matching the sight of the welder and the welding
current. The safety standards suggest colouring
No. 9 (minimum No. 8) for each current below 300
A. A lower shield colouring can be used if the arc is
covered by the workpiece.
• Always use approved safety glasses with side
protection under the helmet or any other cover.
• Use guards for the welding operation sites in order
to protect other people from the blinding light
radiation or projections.
• Always wear earplugs or another hearing protection
to protect against excessive noise and to avoid
spatter entering the ears.
• Bystanders should be warned to not look at the arc.
3.4. PROTECTION AGAINST ELECTRIC SHOCK
ELECTRIC SHOCK CAN BE LETHAL!
• The power cable must be connected to the nearest
socket and placed in a practical and secure position.
Positioning the cable negligently in the room and on
a surface which was not checked must be avoided, as
it can lead to electrocution or fire.
• Touching electrically charged elements can cause
electrocution or serious burns.
