Unpacking
When unpacking, check to make sure that all
components are included. Refer to the drawings
on this manual. If any parts are missing or broken,
please call IVT assistance center.

Initial operation

Always use the correct supply voltage: the power
supply voltage must match the information quoted
on the tool identification plate.

Switching on and off

Before connecting the device to the electric power
supply, make sure that the main supply voltage
is 230V/50Hz and being suitable for use only in
premises having a service current capacity equal
to or greater than 100A per phase with a normal
voltage of 400/230V.
Operating instruction
Welding preparations
1. Connect the earth terminal (2) directly to the
part to be welded or to the support on which the
part is resting.
2. Ensure that the earth terminal is in direct contact
with the part to be welded.
3. 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.
Welding
After you have made all the electrical connections
for the power supply and for the welding circuit, you
can proceed as follows:
1. 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.
2. Ensure that a good electric contact is made.
3. Switch on the welding set at the on-off switch
(4) and set the welding current using the welding
current adjust knob (3) to suit the electrode you
wish to use.
4. 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.
5. Check that you have the correct electrode and
current strength on a test part.
CAUTION: 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°.
CAUTION: Always use tongs to remove
spent electrodes and to move parts that
you have just welded. Please note that
the electrode holder (1) 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. lf you want to continue welding
after an interruption, the slag from your initial
attempt must first be removed.
Overheating protection
The welding set is fitted with an overheating
guard that protects the welding transformer from
overheating. If the overheating guard trips, the
overheating lamp (5) on your set will be lit. Allow
the welding set to cool for a while.
