Use the safety chain to secure the gas cylinder
against falling over.
▸
Remove the gas cylinder before transport.
▸
Pull the mains plug before moving the appliance
or performing work on the appliance.
Intended Use
The device is intended for electrode welding under
commercial and industrial operating conditions. It is
portable and suitable for mains operation or opera-
tion with a power generator.
The device can be used in conjunction with a TIG
torch for TIG welding of, for example:
• Unalloyed, low-alloy and high-alloy steels,
• Copper and its alloys,
• Nickel and its alloys,
• Special metals such as titanium, zirconium and
tantalum.
The device is not intended for TIG welding of alumin-
ium and magnesium.
Environmental Conditions
Temperature range of the ambient air:
• In operation:
-10 °C ... +40 °C (+14 °F ... +104 °F)
• Transport and storage:
-25 °C ... +55 °C (-13 °F ... +131 °F)
Relative humidity:
• Up to 50 % at 40°C (104°F)
• Up to 90 % at 20°C (68°F)
Operation, storage and transport can only occur
inside the specified areas! Use outside these areas is
classed as incorrect use.
The ambient air must be free of dust, acids, corrosive
gases or other harmful substances!
The user is solely responsible for damage
resulting from improper use.

Safety Instructions
▸
To mark the appliance, do not drill holes into the
casing and do not attach rivets. Use stickers.
▸
Use only genuine Würth accessories and
spare parts.
The handle is solely for use when one person is
carrying the machine.
The machine must not be lifted by mechanical
means (e.g. crane, etc.).
The appliance is electronically protected against
overload. Do not, however, actuate the main switch
with the device under load.
The device is cooled by a fan.
Therefore ensure that the air inlet [7] is clear at all
times.
Do not insert any objects through the ventilation
slots. They could damage the fan. Never weld with
a defective fan; arrange for immediate repair of the
machine.
Never use stronger fuses than the fuse rating indi-
cated on the type plate of the device. Transport the
device in a horizontal position using the detachable
handle.
Cyclic duration factor (ED)
The cyclic duration factor (CDF) is calculated based
on a working cycle of 10 minutes. A CDF of 60%
thus corresponds to a welding time of 6 minutes.
Noise / vibration information
The noise emission measured in accordance with
EN 60 974-1 at normal load and maximum operat-
ing point is less than 70 dB(A).
Transport
Attention!
