9. When the welding machine is operating, all its covers and doors must be
closed and well fixed.
10. o not expose the welding machine to direct sunlight or to heavy rain. This
equipment conforms to protection rating IP23S.
11. uring welding, the welding cables must be located near or at ground level.
They should be as short as possible.
12. The operator must wear gloves, clothes, shoes, and a helmet or a welder’s
helmet, which protect and are fire-resistant in order to protect him against
electric shock, flashes and sparks from welding.
13. The operator must protect his eyes with safety visor or mask designed for
welding, fitted with standard safety filters. He should also be aware that during
electrical welding ULTRAVIOLET RA IATION is emitted. Therefore it is vital
that his face is also protected from radiation. Ultraviolet rays produce the
same harmful effect as sun burning on unprotected skin.
14. The operator is obliged to warn anyone near the welding area of the risks
that welding involves and to arrange to provide adequate protection
equipment.
15. It is very important to arrange for sufficient ventilation, especially when
welding in enclosed spaces. We suggest using suitable fume extractors to
prevent the risk of intoxication by fumes or gas generated by the welding
process.
16. The operator must ensure all flammable materials are removed from the
work area to avoid any risk of fire.
17. The operator must NEVER weld containers that have previously contained
petrol, lubricants, gas or similar flammable materials, even if the container
has been empty for a considerable time. THERE IS A VERY HIGH RISK OF
EXPLOSION.
18. The operator must be aware of all the special regulations which he needs
to conform to when welding in enclosed spaces with a high risk of explosion.
19. To prevent electric shock, we strongly suggest the following rules:
20. o not work in a damp or humid environment.

21. o not use the welding machine if its cables are damaged in any way.
22. Make sure that the earthing system of the electric equipment is correctly
connected and operational.
23. The operator must be insulated from the metal components connected to
the return wire.
24. The earthing of the piece being worked could increase the risk of injury to
the operator.
25. EN 60974-1 Standard: Open-circuit voltage. uring the operation of the
machine, the highest voltage, with which it is possible to come into contact, is
the open-circuit voltage between the welding clamps. In our generator this
voltage is 58V.
26. The maximum open-circuit voltage of the welding machines is established
by national and international standards (EN 60974-1) depending on the type
of weld current to be used, on its waveform and on the hazards arising from
the work place. These values are not applicable to the strike currents and
those for stabilisation of the arc that could be above it.
27. The open-circuit voltage, for as many adjustments as possible, must never
exceed the values relating to the various cases shown in the following table:
Case Working conditions Open-circuit voltage
1 Places with increased risk of
electric shock
C current: 113V
peak value
AC current: 68V
peak value and
48V effective
2 Places without increased risk

6. GETTING STARTED MIG/MAG
Getting started must be consistent with technical data and conditions of use.
CHOOSING THE FEEDING ROLL
In all machines (ALFA IN MIG / MAG) rolls with two grooves are used. These
grooves are intended for two different wire diameters (e.g. 0,8 and 1,0 mm).
Rolls for wire feed must comply with the diameter and material of the welding
wire. Only this way a smooth wire feed can be achieved. Irregularities of the wire
feed leads to a poor quality of welding and deformation of the wire.

 

Fig. 5 The influence of the roll groove on the welding wire
INSERTING THE WIRE
1. Open the side cover of the wire feeder space
2. Put the wire spool on the wire spool holder D1 and fix it with the fixing nut
D2.
3. Cut off the curved or damaged end of welding wire and lead it through the
inlet liner E3, and the roll into the liner inside the EURO torch connector
(about 5 cm). Make sure, that you use the suitable groove.
4. Put the pressure arm E2 down in that way, that the teeth or the gear fit and
fix it by setting the lever E1 into vertical position.
5. Adjust the pressure nut that way that it provides constant movement of
wire but it does not deform wire. The adjusting screw is located under the
plastic screw E1.
6. The spool brake is set by the manufacturer. If necessary, the brake can be
adjusted by a screw D1 so that while stopping the feed, spool will be
stopped on time (it will avoid excessive release of wire). However, too tight
brake needlessly strains the feeding mechanism and thus slippage may
occur in the wire rolls.

10. Press the button 39. The welding wire is fed into the torch. After coming
off from the torch tube, screw the current nozzle and gas nozzle on.
11. Before welding, spray the area in a gas hose and current nozzle with a
separation spray, to prevent damage.

14/21
ALFA IN a.s. © www.alfain.eu
ADJUSTMENT OF GAS FLOW
The electric arc and the weld must be perfectly shielded by gas. Too small
amount of gas does not perform the protective atmosphere and on the other
hand to big amount of the gas brings air into the electric arc.
Notice Gas bottle must be well secured against fall. This manual does
not solve the safe securing of gas bottle. Information can be obtained from a
supplier of industrial gases.
1. Connect the gas hose to gas outlet F8 on the valve and the gas inlet to the
gas connector 8.
2. Press the button 38.
3. Turn the adjusting screw F7 at the bottom side pressure reducing valve, until
the meter F6 shows the required flow, then release the button. The optimum
flow is 10-15l/min.
4. After long-term shutdown of the machine or replacement of the torch it is
suitable to blow the pipes with protective gas before welding.

ADJUSTING WELDING PARAMETERS FOR MIG MAN
1. Approximate setting for the MIG / MAG welding current and voltage
corresponds the empirical relationship U2 = 14 +0.05 I2. According to this
relationship, we can determine the required voltage. When setting the
voltage, we expect the decline in voltage during load. The voltage drop is
approximately 4.5-5.0 V at 100 A.
2. By means of the potentiometer 30 select voltage.
3. Then by means of the potentiometer 31 select the appropriate wire speed.
4. By means of the potentiometer 29 tune the arc by changing the levels of
the choke.

0,9 45 - 160 1,0 - 2,3
1,0 45 - 200 1,2 - 7,0
Table of approximate parameter settings
ADJUSTING THE MACHINE FOR ANOTHER WIRE DIAMETER
In all machines ALFA IN MIG / MAG are used rolls with two grooves. These
grooves are intended for two different wire diameters (e.g. 0,8 a 1,0 mm). Groove
can be replaced by removing the rolls and rotating them, or use a different roll
grooves with required dimensions.
1. Open the nut E1 to the right, pressure roll E2 will be opened upward.
2. Unscrew the plastic locking element E5 and remove the roll.
3. If there is a suitable groove on the roll, rotate the roll and place it back on
the shaft and secure it by screwing the element E5.
FLUX CORE WIRE – SETTING THE POLARITY FOR MIG/MAG TORCH
1. It is desirable to have positive polarity on the MIG/MAG torch while welding
with solid wire in majority of cases. The welder is supplied from the production
with positive polarity on the MIG/MAG torch.
2. For welding with flux cored wires it may be necessary to have negative
polarity on the MIG/MAG torch.
3. The middle terminal K3 is connected to the central euro connector of the
MIG/MAG torch. We supply the welder with K3 connected to (+) K1.
4. In case of welding with flux core wire with (-) polarity, connect K3 by means
the bridge K2 with K4 terminal. Use Phillips screwdriver.
5. Make sure you fasten the terminals properly.
6. Connect the ground cable to the (+) panel socket, fig. 1, pos. 7.

Notice
In case, that you want to weld with flux core wire, it is first necessary to remove
the gas nozzle of the torch before starting welding. Furthermore, during the
welding process, you must not touch the weldment with the die. There would be
a risk of baking the wire.

ADJUSTING THE MACHINE FOR WELDING OF ALUMINIUM
For feeding the AL wire it is necessary to use roll with the “U” profile - see
paragraph OVERVIEW ROLLS WIRE FEE . To prevent problems with feeding
use wires with diameter. 1.0 mm of AIMg3 or AlMg. Wire of alloy Al99, 5 or AlSi5
are too soft and easily will cause problems with movement.
For the aluminum welding it is also necessary to provide the torch tefl. liner and
special current nipple. We do not recommend you to use the torch longer than 3
m. Great attention must be paid to adjust the contact power of rolls – it must not
be too high, otherwise there is a deformation of the wire.
As a protective atmosphere is necessary to use argon.
