When you insert the tungsten needle, please note
that it should project around 5 mm out of the ceramic
nozzle.
Please note that you must use a clamping sleeve (9)
which is suitable for the electrode diameter. The
diameter of the ceramic nozzle (3) should be
selected to suit the welding current, the workpiece
thickness, the electrode thickness and the gas
delivery rate. The smaller these values are, the
smaller the diameter of the ceramic nozzle (3) should
be. Thicker tungsten electrodes (10) should be used
for thick workpieces and high welding currents. This
hose package is suitable for using tungsten
electrodes (10) with diameters from 1.6 to 2.4 mm.
For welding points with difficult access and
correspondingly short tungsten electrodes (10), the
short protective cap (11) rather than the long
protective cap (2) can be screwed on to the rear of
the handle (5).
Important.
Please note that for TIG welding, the cable with the
ground terminal (9) must be connected to the
positive pole (5) and the TIG equipment to the
negative pole (6).
Connect the quick-release connector plug (6) to the
negative pole on your welding set and connect the
gas connector (7) to the corresponding connector on
your welding set (Fig. 5).
If your welding set does not have a shielding gas
connector, the gas connector (7) can also be
connected straight to the gas bottle using a pressure
reducer.
7. Operation
Refer to the instructions in the operating manual for
your welding set. Find the ideal settings using a test
workpiece.
Set the gas delivery rate (depending on the welding
current, electrode diameter and the workpiece
thickness) so that a uniform arc can be achieved
(approx. 5 – 15 l/min). Make an initial rough setting
on the pressure reducer on the gas bottle and then
set the precise delivery rate using the rotary valve for
the gas delivery rate (4).
When all the required settings have been made on
the welding set and all the connections have been
made, proceed as follows:

To ignite the torch now place the ceramic nozzle at
an angle to the material you wish to weld and guide
the tungsten needle over the material using even,
rocking movements until an arc is generated.
Maintain a constant distance to the workpiece for
welding (approx. 1 to 1.5 times the electrode
diameter). Put the welding torch and the ground
terminal on an insulated surface when you have
finished the welding.
8. Cleaning, maintenance and ordering
of spare parts
Always pull out the mains power plug before starting
any cleaning work.
8.1 Cleaning
Keep all safety devices, air vents and the motor
housing free of dirt and dust as far as possible.
Wipe the equipment with a clean cloth or blow it
with compressed air at low pressure.
We recommend that you clean the device
immediately each time you have finished using it.
Clean the equipment regularly with a moist cloth
and some soft soap. Do not use cleaning agents
or solvents; these could attack the plastic parts of
the equipment. Ensure that no water can seep
into the device.
8.2 Maintenance
There are no parts inside the equipment which
require additional maintenance.
8.3 Ordering replacement parts:
Please quote the following data when ordering
replacement parts:
Type of machine
Article number of the machine
Identification number of the machine
Replacement part number of the part required

9. Disposal and recycling
The unit is supplied in packaging to prevent its being
damaged in transit. This packaging is raw material
and can therefore be reused or can be returned to
the raw material system.
The unit and its accessories are made of various
types of material, such as metal and plastic.
Defective components must be disposed of as
special waste. Ask your dealer or your local council.
