2 SAFETY PRECAUTIONS
PERSONAL PRECAUTION
. For safety reasons, it is necessary to use welding gloves during welding.
These gloves will protect you before intervention of electric current
(open circuit voltage). It protects you against thermal radiation and
splashing drops of hot metal too. Wear sturdy isolated shoes. Do not wear
open shoes, because drops of hot metal can cause burns.
2. Do not look into the welding arc without eye and face protection.
Always use good quality welding helmet with intact protective filter.
3. The persons appearing in the vicinity of the welding must be informed of
the danger and must be equipped with protective equipment.
4. During welding, especially in small spaces, it is necessary to ensure an
adequate supply of fresh air, because during welding, harmful fumes arise.
5. In tanks of gas, oil, fuel, etc., (even empty ones) do not make welding,
because there is a chance of explosion.
6. In areas with chance of explosion special provisions are applied.
7. Welding machines that are subjected to great exertion must comply with
specific security requirements. These include the rail pressure of the
vessel etc. These connections may only be carried out by competently
trained welders with the necessary permissions.
SAFETY REGUALTIONS
. Before starting work with welding machine, it is necessary to get familiar
with the provisions of the CSN 05060 and norm CSN 050630.
2. With a bottle of CO2 or mixed gases should be handled according to the
regulations for working with pressure vessels contained in CSN 07 83 05.
3. The welder must use protective equipment.
4. Before working on the electrical part, removing the cover or cleaning it is
necessary to disconnect the device from the network.

The machine is equipped with a 6 A plug for connection to a single-phase
supply x 230 V, the corresponding data for this 6 A plug (Duty Cycle = DC)
are in the table above without brackets.
In order to fully use the technical capabilities of the machine, the machine must
be connected to the industrial single-phase networks with a blue plug 32 A with
the maximum permissible fuse of 25 A. The corresponding data for such a 32 A
plug are stated in the table above in brackets.
Another option is to connect the machine to the three-phase mains 3x400 / 230V
TN-S (CS). The condition is to use a 5 pin 32 A plugs for the supply cable and
connection to the phase voltage. Black (brown) wire connected to one phase
(e.g. L ), the blue wire to the neutral wire (N) and green-yellow wire to the
grounded conductor "PE". In this case, it is possible to connect the machine to
a three-phase socket, which may be protected by fuse max. 25 A.
Attention! Do not connect to the interconnected voltage (delta voltage) (between
2 phases)!
Replacement of the plug may only be performed by ALFA IN authorized service
personnel.

11 GENERAL INFORMATION ON THE WELDING
MODES
MMA welding
The manufacturers of the electrodes specify the optimum welding current for
each type of electrode. The type of electrode to be used depends on the
thickness of the material to be welded and on its position.
Insert the chosen electrode into the electrode holder. To strike the electric arc,
rub the electrode against the material to be welded connected to the earth
(ground) clamp. Once the arc is struck, lift the electrode holder slowly to the
normal welding distance.
To strike the arc better, an initial current is supplied which is higher (hot-start)
compared to the welding current. The electrode on melting deposits in the form
of drops onto the piece to be welded and its outer coating is consumed supplying
the shielding gas for the welding. To facilitate the fluidity of the welding arc, while
the drops are coming off, which can cause a short circuit between the electrode
and the weld pool, a momentary increase in the welding current (arc-force) is
given, thus preventing the arc from going out. If the electrode stays stuck to the
piece to be welded, there is an anti-stick function that, after a certain short-circuit
time, cuts off the power to the generator. Thus you can detach the electrode
without damaging it.
When the coating electrodes are used, you need to remove the dross from the
welding after every pass.
TIG welding
In TIG (Tungsten Inert Gas) welding the electric arc is struck between a non-
consumable electrode (pure tungsten or an alloy) and the workpiece in an
atmosphere protected by an inert gas (argon).
The TIG lift-arc process is struck by contact. A low short-circuit welding current
is set to limit the tungsten inclusion on the workpiece. This process does not
guarantee a weld of high quality at the start of the bead.
To completely prevent the tungsten being included, you must not let the
electrode touch the piece to be welded. However you use a start-up with high
frequency (HF) discharge, that allows striking of the electric arc at a distance.
