method for igniting an arc. Check on a test part that
you have the correct electrode and current strength.
Electrode (Ø mm):
1,6
2
2,5
3,2
4,0
Important!
Do not dab the workpiece with the electrode since it
could be damaged, making it more difficult to ignite
the arc.
As soon as the arc has ignited, attempt to keep it a
distance from the workpiece equivalent to the
diameter of the electrode.
This distance should be kept as constant as possible
during the welding process. The angle of the
electrode in the direction in which you are working
should be 20/30°.
Important.
Always use tongs to remove spent electrodes and to
move parts that you have just welded. Please note
that the electrode holder (8) must always be put
down so that it is insulated after you have completed
the welding work.
Do not remove the slag until the weld has cooled.
If you want to continue a weld after an interruption,
the slag from your initial attempt must first be
removed. When removing the slag you should wear
goggles to protect your eyes from sharp and/or hot
slag spatter.
7.2 Welding with TIG equipment (not supplied)
Please note that the appropriate gas for the
material you wish to weld must be used.
Steel (Fe) = ArCO 2
Aluminum (Al) = Ar
(not supported by this equipment)
Stainless steel (V2A) = ArO 2
Connecting the equipment:
1. Connect the gas supply connector to the
pressure reducer on the gas bottle.
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).

2. Connect the TIG equipment to the negative pole
(6) on the front of the device. Connect the cable
with the ground terminal (9) to the positive pole
(5) on the front of the device.
Welding current (A)
40 – 50
3. Connect the TIG equipment to the gas connec-
40 – 80
tor. The gas supply connector must be
60 – 110
connected to the shielding gas bottle via the
80 – 150
pressure reducer. The gas delivery rate can be
120 – 150
set on the pressure reducer and on the handle of
the TIG hose package. A gas delivery rate of
approx. 5 – 15 l/min should be set depending on
the welding current and the material to be
welded.
4. Before you start welding, the tungsten needle
must be sharpened. Which tungsten needle
should be used with which welding current is
shown in the table below:
Electrode (tungsten needle)
diameter (mm)
1.6
2.0
2.4
5. When you insert the tungsten needle, please
note that it should project around 5 mm out of the
ceramic nozzle.
6. Now open the gas valve on the burner.
7. Switch on the device and set the welding current
using the potentiometer (1).
8. 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. Overheating guard and fuse
The welding set is fitted with an overheating guard
that protects the welding transformer from
overheating. If the overheating guard trips, the
control lamp (4) on your set will be lit. Allow the
welding set to cool for a time.
There is an equipment fuse (14) on the rear of the
equipment. If the equipment no longer works, pull the
mains plug out of the socket and open the cover on
the fuse (14) using a screwdriver. If the thread in the
fusible insert has burned out, replace it by a fuse with
the same nominal rating (250 mA, characteristic M).
