-Be kept in a legible state

-Not be damaged/marked

-Not be removed

-Not be covered, pasted, or painted over

For the location of the safety and danger notices on the device, refer to the sec-

tion headed "General" in the Operating Instructions for the device.

Before switching on the device, remove any faults that could compromise safety.

Your personal safety is at stake!

EN-US

Intended Use The device is to be used exclusively for its intended purpose.

The device is intended exclusively for the welding process specified on the rating

plate.

Utilization for any other purpose, or in any other manner, shall be deemed to be

"not in accordance with the intended purpose." The manufacturer is not respons-

ible for any damage resulting from improper use.

Proper use also means

-Completely reading and obeying all instructions in the Operating Instruc-

tions

-Completely reading and obeying all safety instructions and danger notices

-Carrying out all the specified inspection and servicing work

Never use the device for the following applications:

-Thawing pipes

-Charging batteries

-Starting motors

The device is designed for operation in industry and business. The manufacture

shall not be liable for any damage resulting from use in a living area.

The manufacture shall also not be liable for faulty or incorrect work results.

Environmental

Conditions

Operation or storage of the device outside the stipulated area will be deemed as

not in accordance with the intended purpose. The manufacturer accepts no liab-

ility for any damage resulting from improper use.

Temperature range of the ambient air:

-During operation: -10°C to +40°C (14°F to 104°F)

-During transport and storage: -20°C to +55°C (-4°F to 131°F)

Relative humidity:

-Up to 50% at 40°C (104°F)

-Up to 90% at 20°C (68°F)

Ambient air: free of dust, acids, corrosive gases or substances, etc.

Altitude above sea level: up to 2000 m (6561 ft. 8.16 in.)

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

-Are trained according to the requirements for the work results

The safety-conscious work of the personnel must be checked regularly.

Obligations of

Personnel

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.
