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.

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 forward, pressure rolls E2 will be opened upward.
2. Unscrew the locking element 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.
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 OF ROLLS FOR WIRE FEED. 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.

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. If a spool (size of 15 or 18 kg is used, put on each side of the spool
adapter D3. The hole in the back of the adapter must fit into the pin on the
wire spool holder!

13/30
ALFA IN a.s. © www.alfain.eu
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. By pressing the button A10, placed in the
space of the wire feeder, turn on the motor of the feeder. The adjusting
screw is located under the plastic screws 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.
Fig. 5 - Spool holder
ADJUSTING PRESSURE FORCE OF FEED ROLLS
Important thing for reliable operation of the feeding mechanism is the size of
pressure force of feed rolls.
The amount of force depends on the type of welding wire, for aluminum or tube
wire, we choose a smaller pressure force.
If the pressure force is too small, slippage may occur and thus irregular wire
feeding speed.
If the pressure force is too high, it will lead to increased mechanical wear of
bearings and it can damage the machine. Before putting into operation, clean
the rolls from preservative oil.

INSERTING THE WIRE TO THE TORCH AND CONNECTION OF EARTH
CA LE
1. Connect the earthling clamps to the welder or to the welding table.
2. Notice When inserting the wire do not point with torch to the eyes!
3. Screw the central end of the torch 2 to connector 1 on the machine
while the machine is turned off.
4. Remove the gas nozzle from the torch.
5. Unscrew the current nozzle.
6. Connect the machine to power supply.
7. Turn the ON/OFF switch to ON.
8. Press button A10 in the space of wire feeder to run the motor of the feeder.
The welding wire is fed into the torch. After coming off from the torch tube,
screw the current nozzle and gas nozzle on.
9. Before welding, spray the area in a gas hose and current nozzle with a
separation spray, to prevent damage.
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. Fit the gas hose to the outlet on the back panel of the machine.
2. Press button V1 (pic. 7 on the main panel to the switching of the gas valve.
If you hold the button for less than 3 s, after releasing the button, the gas
valve will turn off. If you hold the button for more than 3 s, it will turn off the
gas valve after about 20 s, or after pressing any button.
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.
