See Figure 3-12.
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 (4).
Please follow the operating instructions, as described
max. 160 A
below:
Please observe the following instructions in order to
avoid the risk of fire, electric shock or personal
injuries.
3 ~
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.
Please note:
The welding set is fitted with two power cables and
plugs. Connect the appropriate plug to the
corresponding power supply (230 V plug to a 230 V
socket or 400 V plug to a 400 V socket).

55-160 A
Connect the earth terminal (2) direct to the part to be
3,2 3,2 4,0
welded or to the support on which the part is resting.
Ensure that the earth terminal is in direct contact with
115 160
the part to be welded. You should therefore avoid
coated surfaces and/or insulated materials. The
115 140
electrode holder cable has a special clamp at one
134 75
end, which is used to secure the electrode. The
welding safety shield must be used at all times for
899 1036
welding. It protects your eyes from the radiation
emitted by the arc and nevertheless enables you to

watch the welding process.

8. Welding
After you have made all the electrical connections for
16
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°.
Important!
Always use tongs to remove spent electrodes and to
