1. SAFETY INSTRUCTIONS AND WARNINGS
PERSONAL PROTECTION
1. For safety reasons, protective gloves must be worn during welding. These
gloves protect you from electric shock (circuit voltage at no load). It also
protects you from heat radiation and splashing drops of hot metal.
2. Wear sturdy insulated shoes. Open shoes are not suitable, as drops of hot
metal can cause burns.
3. Do not look into the welding arc without face and eye protection. Always
use a high-quality welding helmet with an intact protective filter.
4. Ensure that the insulation of the torch and grounding cable is in good
condition.
5. Persons near the welding site must also be informed of the danger and
provided with protective equipment.
6. When welding, especially in small spaces, it is necessary to ensure a
sufficient supply of fresh air, as welding produces harmful emissions.
7. Do not perform welding work on gas, oil, fuel, etc. Tanks (even empty ones)
as there is a risk of explosion.
8. Special regulations apply in potentially explosive atmospheres.
9. Welded joints that are subject to high stress must meet special safety
requirements. These are mainly rails, pressure vessels, etc. These joints
may only be made by qualified, trained welders with the necessary
authorization.
SAFETY REGULATIONS
1. Before starting work with the welding machine, getting acquainted with the
provisions in EN 050601 –Safety provisions for metal welding and the
standard EN 050630 –Safety provisions for arc welding of metals is
necessary.
2. The CO2 bottle of mixed gases must be handled following the regulations
for working with pressure vesselscontained in EN 07 8305and EN 078304.
The requirements of EN 07 8304 may limit the size of the gas bottle that
can be placed on the machine platform.
3. The welder must use protective equipment.
4. Disconnect the device from the mains before working on the electrical
system, cleaning it, or removing the cover.

2. OPERATING CONDITIONS
1. The device may only be operated by trained personnel within the technical
regulations. The manufacturer is not liable for damage caused by improper
use and operation. Only use original spare parts from ALFA IN for
maintenance and repairs.
2. The device complies with IEC 61000-3-12.
3. The welding machine is tested according to the standard for degree of
protection IP 23S, which protects against the intrusion of solids with a
diameter greater than 12 mm and protection against the intrusion of water
falling in a vertical to the oblique direction to a slope of 60˚.
4. Operating ambient temperature between -10 to +40 °C.
5. Relative humidity below 90% at +20 °C.
6. As high as 3000 meters above sea level.
7. Connecting more than one generator in series or parallel is prohibited.
8. The machine must be located so the cooling air can enter and exit through
the cooling vents without restriction. Care must be taken to ensure that no
mechanical particles, especially metal particles, are sucked into the
machine (e.g., during grinding). Cooling is driven by electronic temperature
automation.
9. For the welding machine, it is necessary to perform a periodic inspection
once every 6/12 months by an authorized employee according to EN
331500 and EN 050630 –see paragraph Maintenance and service tests.
10. An authorized person may only carry out all interventions in the
electrical equipment and repairs (disassembly of the mains plug,
replacement of fuses).
11. The manufacturer sets the welding machine to 230 V with a tolerance
range of 110 - 230 V ± 10 %, which allows the operation of the machine in
the mains ~230 V and ~110 V.
12. The relevant mains voltage and power supply must match the mains
plug.
CautionExtension cables must have conductors with cross-
sections larger than 3x2,5 mm2. Welder can be operated on a single-phase
power generator of 8 kVA (1x230V/50Hz) or more, with a voltage
stabilization of ± 15%. Generators with lower power can damage the
machine.
CautionIf the machine is transported from a colder place to a much
warmer location, moisture condensation might occur, particularly inside the
welder. This could decrease electrical strength and increase the likelihood of

7. MACHINE PREPARATION FOR MIG/MAG METHOD
CHOOSING THE FEEDING ROLL
All machines (ALFA IN MIG / MAG) use rolls with two grooves. 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 lead to poor welding quality and deformation of the wire.
  

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 the welding wire, lead it through the
inlet liner E3, and roll it into the liner inside the EURO torch connector
(about 5 cm). Make sure that you use a suitable groove.
4. Put the pressure arm E2 down so that the teeth or the gear fit and fix it by
setting lever E1 vertically.
5. Adjust the pressure nut so that it provides constant movement of the wire
but does not deform it. The adjusting screw is located under the plastic
screw E1. The clamping force of the feed rolls is essential for the reliable
operation of the feeding mechanism. The size of the force depends on the
type of welding wire. For Aluminium or tubular wire, choose a smaller
clamping force. If the clamping force is insufficient, rolls can slip, which
results in the feed speed being irregular. If the contact force is too high, the
mechanical wear of the bearings increases, the pressure mechanism does
not fulfil its protective function, and in case of increased resistance of the
wire feed (damaged or dirty Bowden, baked wire in the feedthrough, etc.),
the slipping does not occur, and there is a risk of the wire being displaced
sideways. In the extreme case, the motor may be blocked entirely, and the
gearbox will be unduly mechanically stressed. The electric motor and the
controller's power output could be overloaded and damaged.
6. Clean the pulleys of preservative oil before starting up.

7. The manufacturer sets the spool brake. If necessary, the brake can be
adjusted by a screw D1so that while stopping the feed, the spool is stopped
on time (This avoids the excessive release of wire). However, a too-tight
brake needlessly strains the feeding mechanism, and thus slippage may
occur in the wire rolls.

INSERTING THE WIRE TO THE TORCH AND CONNECTION OF THE
GROUNDING CABLE
1. Connect the MIG/MAG torch to the EURO connector A5 on the machine
while the machine is turned off.
2. Connect the grounding cable to the quick connector A4 (-).
3. Connect the grounding clamps to the welder or the welding table.
4. NoticeWhen inserting the wire, do not point with a torch to the eyes!
5. Remove the gas nozzle from the torch.
6. Unscrew the current nozzle.
7. Connect the machine with the mains plug to the 1x230 V/50-60 (1x110
V/50-60) Hz mains and switch it on with the main switch V6 located on the
front panel of the welder.
8. MENU button V2 and encoder V1 select desired MIG/MAG program.
9. In the submenu of welding parameters settings, select two-stroke or four-
stroke.
10. Press the torch button, and the welding wire is fed into the torch. After
the wire has run out of the torch tube, screw in the current pass and gas
nozzle.
11. Before welding, spray the area in the gas nozzle and the jet tube with
a separating spray to prevent the spatter from sticking.
