Obligations of
the Operating
Company
The operating company must only allow persons to work with the device if they
-Are familiar with the basic occupational safety and accident prevention regu-
lations and are trained in handling the device
-Have read and understood these Operating Instructions, especially the sec-
tion "Safety Rules," and have confirmed this with their signature

All persons who are assigned to work with the device must do the following be-
fore beginning the work:
-Follow the basic regulations for occupational safety and accident prevention
-Read these Operating Instructions, especially the section "Safety Rules," and
confirm that they have understood and will follow them by signing
Before leaving the workplace, ensure that no personal injury or property damage
can occur in one's absence.

Grid Connection Devices with a high output can influence the energy quality of the grid due to
their current consumption.
This may affect a number of device types in terms of:
-connection restrictions
-criteria regarding maximum permissible grid impedance *)
-criteria regarding the minimum required short-circuit power *)
*) both at the interface with the public grid
See technical data
In this case, the operator or the person using the device should check whether or
not the device is allowed to be connected, where appropriate through discussion
with the power supply company.
IMPORTANT! Ensure secure grounding of the grid connection!
Personal Protec-
tion and Protec-
tion of Others
You are exposed to numerous hazards while handling the device, for example:
-Flying sparks and pieces of hot metal
-Arc radiation that poses a risk of injury to the eyes and skin
-Hazardous electromagnetic fields that pose a risk of death for individuals
with pacemakers
-Electrical risks from grid current and welding current
-Increased noise exposure
-Harmful welding fumes and gases
Wear suitable protective clothing when dealing with the device. The protective
clothing must have the following properties:
-Flame resistant
-Insulating and dry
-Covering the entire body and in good condition with no damage
-Safety helmet
-Cuffless pants
Protective clothing involves the following:
-Protecting the face and eyes from UV radiation, heat and flying sparks with a
face guard featuring a regulation-compliant filter
-Wearing regulation-compliant protective goggles with side protection behind
the face guard
-Wearing rigid, wet-insulating footwear
-Protecting hands with appropriate gloves (featuring electrical insulation and
thermal protection)
-Wearing ear protection to reduce noise exposure and protect against injury
Keep persons, especially children, away during the operation of the devices and
during the welding process. If persons are in the vicinity, however:
-Instruct them about all hazards (blinding hazard due to arcs, risk of injury
from flying sparks, welding fumes hazardous to health, noise exposure, pos-
sible hazard due to grid current or welding current, etc.)
-Provide suitable protective equipment or
-Construct suitable protective walls and curtains.
Danger from tox-
ic gases and va-
pors
The fumes produced during welding contain toxic gases and vapors.
Welding fumes contain substances that cause cancer, as stated in monograph
118 from the International Agency for Research on Cancer.

EN-US

Use at-source extraction source and a room extraction system.
If possible, use a welding torch with an integrated extraction device.
Keep your head out of the welding fumes and gases.
Take the following precautionary measures for fumes and harmful gases:
-Do not breathe them in.
-Extract them from the work area using appropriate equipment.
Ensure that there is a sufficient supply of fresh air. Ensure that there is a ventila-
tion flow rate of at least 20 m³ per hour.
Use a welding helmet with air supply if there is insufficient ventilation.
If there is uncertainty as to whether the extraction capacity is sufficient, com-
pare the measured toxic emission values against the permissible limit values.
The following components are factors that determine how toxic the welding
fumes are:
-The metals used for the workpiece
-Electrodes
-Coatings
-Cleaning agents, degreasers, and the like
-The welding process used
Consult the corresponding material safety data sheets and manufacturer's in-
structions for the components listed above.
Recommendations for exposure scenarios, risk management measures and
identifying working conditions can be found on the European Welding Associ-
ation website under Health & Safety (https://european-welding.org).
Keep flammable vapors (such as solvent vapors) out of the arc radiation range.
When no welding is taking place, close the valve of the shielding gas cylinder or
the main gas supply.
Danger from Fly-
ing Sparks
Flying sparks can cause fires and explosions.
Never undertake welding near flammable materials.
Flammable materials must be kept at least 11 meters (36 ft. 1.07 in.) from the
arc or protected with a certified cover.
Keep suitable, tested fire extinguishers on hand.
Sparks and pieces of hot metal may also get into surrounding areas through
small cracks and openings. Take appropriate measures to ensure that there is no
risk of injury or fire.
Do not undertake welding in areas at risk of fire and explosion, or on sealed
tanks, drums, or pipes if these have not been prepared in accordance with cor-
responding national and international standards.
Do not undertake welding on containers in which gases, fuels, mineral oils, and
the like are/were stored. Residues pose a risk of explosion.
Risks from grid
current and
welding current
An electric shock can be fatal.
Do not touch voltage-carrying parts inside or outside the device.
