1. WARNING AND INFORMATION SIGNS

2. APPROPRIATE USE (FIELD OF APPLICATION)
• Outdoor operation is impermissible. Use this device only
in dry rooms!
• „M280“: The application of spot welds on steel alloys as
well as various non-ferrous metals.
GENERALLY NO LIABILITY IS ACCEPTED FOR THE DURABILITY OF THE WELDING. WE RECOMMEND THAT
THE WELDING BE CHECKED IN EVERY CASE.
• Eye protection system: Observation and microscopic
viewing of objects through the ocular of the
microscope/optic unit and illumination of the working
area.
• Eye protection system: may only be used for welding if it
has been properly connected to a M280 fine-welding
device.
3. SAFETY INSTRUCTIONS
3.1 GENERAL SAFETY REQUIREMENTS
PERSONS WHO WEAR ACTIVE IMPLANTS (HEART PACEMAKERS) MUST MAINTAIN A SAFETY
DISTANCE OF 20CM BETWEEN THE WELDING CURRENT CABLE / SOURCE OF THE WELDING
CURRENT AND THE IMPLANT.
The opening of the device is only permitted when
undertaken by an electrician. Before opening
remove the mains cable and ensure that the device
is de-energised. Discharge any components in the device
that could hold electrical charge.
In case of doubt or uncertainty, always consult with a
specialist. Our customer support department is naturally
always available to assist you with their professional
trained personnel, appropriate tooling and equipment.
Always use the original cables and ensure that workpiece
clamps are properly attached.
Both the mains and welding currents can be a source of
danger.
Always remove the mains plug when exchanging the LED
unit. (Only use original replacement LED units from
Lampert).
The device must be isolated from the mains power when
undertaking any repair or maintenance work on the power
source. The power socket is to be clearly blocked when
undertaking any work on the system beyond minor
manipulations where it is necessary to leave the workplace,
even for brief periods.
The highest and thus the most dangerous voltage in the
welding circuit is the no-load voltage. The highest
permissible no-load voltages are recorded in the national
and international regulations in accordance with the type of
welding current, construction of the current source and the
extent of the electrical hazard to the workplace.
If it can be assumed that risk-free operation is no longer
possible, the unit must be put out of operation and secured
against being unintentionally restarted.
It can be assumed that risk-free operation is no longer
possible, if
• the equipment shows visible signs of damage,
• malfunctions occur,
• or the equipment is no longer working.
The „M280“ must, as standard, be operated with a mains
voltage of 230V~.
Yellow-green wire = protective earth terminal (PE). The
other wires L1 and N are to be connected to the phase and
neutral conductors of the power plug.
Mains power is defined as 230V Europe-wide since
introduction of Euro Norm IEC 38 (valid from May 1987).
The welding device is factory-adjusted to 230V!
This means that as a result of the tolerance range +/-10%,
the system can also be operated at 220V~. Devices
configured to voltages other than 230V will be designated
as such by means of a label.
THE DEVICE MUST ONLY BE OPENED BY
AUTHORISED SERVICE PERSONNEL!
IF THE DEVICE HAS BEEN CONFIGURED FOR A
CUSTOM VOLTAGE, THE TECHNICAL DATA ON THE
DEVICE SPECIFICATION PLATE APPLY! MAINS PLUGS
MUST CORRESPOND TO THE MAINS VOLTAGE AND
POWER CONSUMPTION OF THE WELDING
EQUIPMENT (see technical data!)
THE FUSING FOR THE MAINS SUPPLY MUST BE
MATCHED TO THE POWER CONSUMPTION OF THE
WELDING EQUIPMENT!
ONLY USE THE SUPPLIED MAINS CABLE!
THE M280 IS A PIECE OF ELECTRICAL EQUIPMENT. NATIONAL REGULATIONS ON TESTING INTERVALS
AND THE SCOPE OF REQUIRED RECURRING SAFETY-RELATED TESTS MUST BE OBSERVED.

3.2 HAZARDS AND PERSONAL BODY PROTECTION
Please also observe the relevant regulations of the respective country.
RISK OF INJURY FROM RADIATION OR HEAT:
Protective gloves must be worn when welding.
Uncovered areas of the skin must be protected from the
UV radiation generated during welding in order to avoid
skin damage.
Wear suitable dry protective clothing with no synthetic
fibers.
The workpiece and the electrode tip can become very hot
during welding – risk of burns.
Welding can cause sparks and spatters – risk of burns.
EYE PROTECTION WHEN WELDING:
Never look into the arc without eye protection; always use
a welding mask with certified protective glass.
In addition to light and thermal radiation, which can cause
dazzling and burning, the electric arc also emits UV
radiation. With insufficient protection this invisible
ultraviolet radiation causes very painful conjunctivitis,
which can first be noticed hours later, and can also cause
permanent eye damage.
The Lampert eye protection systems with its integrated
LCD protective welding screen offers reliable protection
against these risks and provides permanent protection
from UV / IR rays in both light and dark state. The
protective class of the filter is defined such that dazzling
by the arc is effectively prevented.
Persons who are nearby to the electric arc and assistants
must also be informed of the dangers and equipped with
the appropriate protection; if necessary set up protective
partition walls.
EYE PROTECTION WHEN OPERATING THE LED
ILLUMINATION:
Never look into the LED lamp or its reflections without eye
protection; use protective shield or safety glasses with
suitable protective glass.
SMOKES AND GASES:
When welding, especially in small spaces, ensure that
there is an adequate fresh air supply or use an external
extractor fan, as smoke and hazardous gases occur.
EXPLOSION HAZARD – DANGER WHEN
WELDING ON CONTAINERS:
It is not permitted to carry out welding on containers that
have been used for storing gases, propellants, mineral
oils or similar, even if they have been empty for a long
time, as there is a risk of explosions caused by residues.
Particular regulations apply to fire and explosion
endangered spaces.
OTHER DANGERS:
The electrode tip installed in the handpiece means a risk
of injury (stabbing and scratching of e.g. hand, face and
eyes).
3.
3 HAZARDS OF SHIELDING GAS CYLINDERS:
Observe all applicable safety measures when
ha
ndling gas cylinders as well as the safety
regulations for handling gases. Gas tanks must especially
be secured against falling over / falling down and heat
(max. 50°C); it is particularly important to ensure they are
not subjected to sunlight for extended periods and that they
are protected from severe frost.
3.4 RISK OF ALLERGIC REACTIONS:
Please note that the device's raw materials that
could come into contact with the operator's skin
may cause allergic reactions in susceptible people.
4. SETUP AND INSTALLATION
4.1 SET-UP OF THE DEVICE
The system is to be set up so that cooling air is able to
reach all of the surfaces of the housing without hindrance.
The device may not be covered! The device is to be placed
on a non-combustible surface! The device should be set up
on a base that is solid, level, and insulated - ideally on a
suitable workbench.

4.3 CONNECT EYE PROTECTION AND LED ILLUMINATION TO THE „M280“:
The circular connector for the eye protection system and
the LED illumination should be inserted into the connecting
socket (3) on the rear of the „M280“ welding device and is
to be tightened in place with the coupling nut (hand tight).
WARNING!
ONLY SUITABLE ORIGINAL EYE PROTECTION
SYSTEMS FROM LAMPERT MAY BE CONNECTED TO
THE WELDING SYSTEM!
OTHER EYE PROTECTION SYSTEMS ARE NOT
APPROVED AND CAN LEAD TO PERMANENT HEALTH
DAMAGE OR DAMAGE TO THE WELDING DEVICE.
ALWAYS OBSERVE THE OPERATING INSTRUCTIONS FOR THE CONNECTED EYE PROTECTION SYSTEM
4.4 CONNECT SHIELDING GAS SUPPLY:
Fasten the suitable flow regulator with the corresponding
tool to the shielding gas tank. ATTENTION: In doing so,
always observe the enclosed special operating instructions
provided. (Where possible, use argon with min. 99.9%
purity, e.g. "Argon 4.6"). The pressure hose is to be
fastened by hand with the help of the quick coupling
adapter to the flow regulator as well as the shielding gas
connector (7) on the rear of the device.
CHECK REGULARLY THAT ALL OF THE HOSE CONNECTIONS AND GAS HOSES ARE IN OPTIMAL
CONDITION, ARE PROPERLY FASTENED AND ARE AIRTIGHT!
