The welding times apply for an ambient temperature
of 40° C.
5. Assembly Instructions
See Figure 5-10.

6. Power supply

This welding set can be operated with a rated
voltage of 230 V and 400 V. The desired rated
voltage can be set by means of the rotary switch
illustrated in Figure 2-4. Please follow the operating
instructions, as described below:
Figure 2:
In its initial position the rotary switch is set to 400
Volt. The welding set is operated at a rated voltage
of 400 Volt in a closed electric circuit. To prevent
accidental selection of the wrong rated voltage,
please secure the setting position by inserting a
screw into the respective hole on the left below the
rotary switch.
Figure 4:
To operate the appliance with a rated voltage of 230
V, please slacken and remove the screw located
below the rotary switch on the left and then turn the
switch to the desired position, which is labeled 230
V. After this, please tighten the screw in the marked
drill hole located below the rotary switch on the right.
Please observe the following instructions in order to
avoid the risk of fire, electric shock or personal
injuries.
Never use the appliance with a rated voltage of
400 V if the appliance is set to 230 V. Caution:
Fire risk!
Please disconnect the appliance from the power
supply before setting the rated voltage.
Adjusting the rated voltage during operation of the
welding set is strictly prohibited.
Before operating the welding set, please ensure
that the rated voltage selected on the appliance
complies with that of the power source.
Note:
The welding set is supplied with 2 power cables and
plugs. Please connect the appropriate plug to the
appropriate power source (connect a 230 V plug to a
230 V socket-outlet and a 400 V plug to a 400 V
socket outlet)

7. Welding preparations

Connect the earth terminal (-) (2) direct to the part to
be welded or to the support on which the part is
resting. Ensure that the earth terminal (-) is in direct
contact with the part to be welded. You should
therefore avoid coated surfaces and/or insulated
materials. The electrode holder cable has a special
clamp at one end, which is used to secure the
electrode. The welding safety shield must be used at
all times for welding. It protects your eyes from the
radiation emitted by the arc and nevertheless
enables you to watch the welding process (not
included in items supplied).
8. Welding
After you have made all the electrical connections for
the power supply and for the welding circuit, you can
proceed as follows:
Insert the unsheathed end of the electrode into the
electrode holder (1) and connect the earth terminal
(-) (2) to the part you wish to weld.
Ensure that a good electric contact is made.
Switch on the welding set at the switch (4) and set
the welding current using the hand wheel (3) to suit
the electrode you wish to use.
Hold the safety shield in front of your face and rub
the tip of the electrode on the part you wish to weld
as if you were striking a match. This is the best
method of igniting the arc.
Check that you have the correct electrode and
current strength on a test part.

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°.
