space (free of iron powder, dust and paint).
• Place the welding appliance on a firm and flat
surface and at least 20 cm from the wall.
• Protect the welding appliance against rain and
strong sunlight.
The welding mask

• Slide the handle on the welding mask until it
locks.
• Place the light glass (protective glass) in front
of the dark welding glass. Slide both glasses
in front of the opening.
• Make sure that the glasses are positioned so
that no (harmful) light can now penetrate the
opening.
• Replace the light protective glass when the
view of the workpiece becomes insufficient
during welding. Replacing the dark welding
glass is considerably more expensive than
replacing the light protective glass.
Fitting new electrodes
The electrode consists of a metal core enclosed
by a coating. At one end of the electrode the core
is not covered by the coating.
• Press the handle of the electrode holder
against
the spring.
• Place an electrode with uncoated end (± 2 cm)
in the electrode holder. Make sure that the
non-coated part makes good contact with the
metal part of the electrode holder (electrode
not pushed too far in the electrode holder).
• Release the handle of the grip. The electrode
is now fixed.
N.B! Do not allow the electrode to burn to
lengths shorter than ± 5 cm because of
overheating and/or the deformation of the
electrode holder. The burnt up electrode
will then be difficult to remove.
Removing used electrodes
Press the grip of the electrode holder against the
spring so that the burnt up electrode can fall from
the holder.
N.B! Do not remove the electrode from
the holder by hand. The electrode is very
hot!

N.B! Watch where the waste electrode
falls to prevent a fire hazard and possible
injury.
Installation
Fig. 4
Only an authorized electrician is allowed
to connect the correct plug to the welding
machine.
• Place the blocking screw (A) in the correct
position for 230V(4a) or 400V (4b). (See Fig. 4
a,b,c)
• Warning: When the switch is on position
"230V", the wiring L, N and PE in the power
cord should be connected with the mains
power supply. When the switch is on position
"400V", the wiring L1, L2 and PE in the power
cord should be connected with the mains
power supply. Above that a suitable fuse has
to be used.

Before use:
a. General information about electric arc welding
b. The electrode
c. Protective clothing
d. Face protection
e. Working environment
a. General information about electric arc
welding
The temperature of the arc amounts to approx.
7000° Celsius, so the end of the electrode and the
workpiece fuse. For as long as the arc is
maintained, the electrode will melt and supply the
necessary welding material to the parts to be
joined. The distance between the electrode and
the workpiece must be as short as possible
(approx. 1.5 - 4 mm) depending on the diameter
and type of electrode. The current needed for
welding is supplied by the welding appliance.
The power required by the welding appliance
depends on the work to be done.
Make sure that the electrodes are completely dry,
as moist electrodes cause problems. If the
electrode sticks to the workpiece during welding
your current intensity is set too low.
b. The electrode
• The electrode consists of a metal core
enclosed by a coating. The coating has the
most important purpose of protecting the
