bearing limits.
If it is to be transported by means of a haulage vehicle (transport trolley, forklift etc.), make sure
of the durableness of the vehicle, and the connection points (carrying suspenders, straps, bolts,
nuts, wheels, etc.) that connect the machine to this vehicle.
• If the machine will be carried manually, make sure the durableness of the machine apparatuses
(carrying suspenders, straps, etc.) and connections.
• Observe the International Labor Organization’s rules on carriage weights and the transport
regulations in force in your country in order to ensure the necessary transport conditions.
• Always use handles or carrying rings when relocating the power-supply sources. Never pull
from torches, cables or hoses. Be absolutely sure to carry gas cylinders separately.
• Remove all interconnections before transporting the welding / cutting equipment, each being
separately, lift and transport small ones using its handles, and the big ones from its handling
rings or by using appropriate haulage equipment, such as forklifts.

• In cases where the workpiece cannot be connected to the ground due to electrical safety, or
because of its size and position (for example, in building marine vessel bodies or in steel
construction manufacturing), a connection between the workpiece and the grounding may
reduce emissions in some cases, it should be kept in mind that grounding of the workpiece may
cause users to sustain injuries or other electrical equipment in the environment to break down.
In cases where necessary, the workpiece and the grounding connection can be made as a direct
connection, but in some countries where direct connection is not permissible, the connection
can be established using appropriate capacity elements in accordance with local regulations
and ordinances.

• The operator’s body and head should be kept as far away from the welding / cutting machine
and cables as possible,
• Welding / cutting and electric cables should not be wrapped around the body of the machine in
any way,
The body of the machine should not get caught between the welding / cutting cables. The source
cables must be kept away from the body of the machine, both being placed side by side,
• The return cable must be connected to the workpiece as close as possible to the work area,
• The welding / cutting machine should not rest against the power unit, ensconce on it and not
work too close to it,
• Welding / cutting work should not be performed when carrying the wire supply unit or power
unit.
EMF may also disrupt the operation of medical implants (materials placed inside the body), such
as pacemakers. Protective measures should be taken for people who carry medical implants. For
example, access limitation may be imposed for passers-by, or individual risk assessments may be
conducted for welders. Risk assessment should be conducted and recommendations should be
made by a medical professional for users who carry medical implants.

Welding may be dangerous. Proper working conditions should be ensured and necessary
precautions should be taken. Specialists are responsible for the machine and have to be equipped with the
necessary equipment and those who are not relevant should be kept away from the welding area.
This device is not compatible with IEC 61000-3-12. If it is desired to connect to the low voltage mains used
in homes, it is essential that the installer or the person who will operate the machine to make the electrical
connection has information on the machine’s connectivity. In this case the responsibility will be assumed
by the person who will perform the installation or by the operator.
The safety symbols and warning notes on the device and in the operating instructions must be observed
and the labels must not be removed.
Grids are intended for ventilation. The openings should not be covered in order to provide good cooling and
no foreign objects should be inserted.

Start the machine with the on/off switch and check whether the LEDs are on and the cooling fan is working.
Insert the TIG torch’s plug into the negative pole welding socket and tighten it by turning to the right. Attach the
torch trigger connector that came with the machine to the trigger control cables of the torch. Then connect the
connector to the trigger control socket.
Connect the gas hose of the torch to the gas outlet.
In water-cooled models, connect the cold “blue” hose of the torch to the cold water outlet on the machine, and
the hot “red” hose to the hot water inlet on the machine.
Check for the correct mains voltage before connecting the machine to the mains.
When plugging the power plug into the outlet, make sure that the power switch is set to “0” in
the turned-off position.

• Connect the cold (blue) water hose to the cold water outlet on the water cooling system, and the hot (red) water
hose to the hot water inlet on the water cooling system.
• Magmaweld welding machines come with Magmaweld coolant, which is produced to give the best performance.
In case of lack of coolant, open the coolant reservoir cap and add Magmaweld coolant suitable for the
temperature of the working environment. The coolant must be within the minimum and maximum values
shown on the front panel of the unit.
Different coolant or water should not be added. Different liquid additives can cause chemical reactions or
different problems.
Magmaweld is not responsible for the risks that may arise in case of adding different liquids. All warranty
provisions will be void if different coolant or water is added to the Magmaweld coolant.
If it is desired to use a different brand of coolant, the inside of the coolant tank should be completely empty and
there should be no residue or liquid in it.
It is not suitable to use the water-cooling units with welding machines other than manufactured by Magma
