SELECTING A FEED PULLEY
All ALFA IN MIG/MAG machines use double groove pulleys. These grooves are
designed for two different wire diameters (e.g. 0.8 and 1.0 mm).
The wire feed pulleys must be suitable for the diameter and material of the
welding wire. Only in this way can a smooth wire feed be achieved. Irregularities
in wire feed lead to poor welding quality and wire deformation.

ADJUSTING THE FEED FOR A DIFFERENT WIRE DIAMETER
All ALFA IN MIG/MAG machines use pulleys with two grooves. These grooves
are designed for two different wire diameters (e.g. 0.8 and 1.0 mm). The groove
A

B Wrong
C Wrong

12/33
ALFA IN a.s. © www.alfain.eu
can be changed by removing the pulleys and turning them, or by using other
pulleys with grooves of the required dimensions.
1. Unscrew the clamping nuts E1 towards the front of the four-post slide, the
pressure pulleys E2 open upwards.
2. Unscrew the locking part and remove the pulley.
3. If there is a suitable groove on the pulley, turn the pulley over and put it
back on the shaft and secure it by screwing in the piece.
FEED ADJUSTMENT FOR ALUMINIUM WIRE
1. Replace rollers G2 for rollers G2 with U profile of the groove for AL welding.
2. Allow nut G5 on the EURO connector.
3. Replace the Torch used on steel for an aluminium Torch or at least replace
the Torch cable with a teflon one.
4. Remove the capillary from the EURO G1 connector.
5. Trim the end of the teflon bowden cable so that it is close to the G2 feed
pulley. Thread collet G3, o-ring G4, nut G5 on the ned of the teflone cable
brass pipe G7 for stabilization G7. Tighten nut G5.
Place the Torch on the EURO connector G1 and insert the wire into it.

INTRODUCING THE WIRE INTO THE FEED
1. Open the coil cover and release the lock D2 on the coil holder D1. Insert
the wire coil reducer D3 and the wire coil on top of it, secure with lock D2.
Before doing so, ensure that the mandrel is inserted into the appropriate
hole in the wire reducer or coil.
2. If necessary, it is possible to adjust the braking force with screw D4 so that
the wire does not unwind from the spool after the wire feed has stopped.
3. Cut the end of the wire attached to the edge of the coil and feed it into the
bovden E3 through the pulleys E5 and about 5 cm inside the EURO

13/33

connector tube E4. Check that the wire runs through the correct groove of
the pulley.
4. Fold down the pressure arms E2 and return the clamping nuts E1 to the
vertical position.
5. Adjust the pressure of the clamping nut to ensure smooth movement of the
wire without deforming the wire. Press button A13, located in the feed area
of the machine, to start the feed motor. The adjustment screw is located
under the plastic screws E1.
6. The coil brake is set by the manufacturer. If necessary, it can be adjusted
with screw D4 so that when the feed stops, the coil stops in time and the
wire does not become too loose. However, an over-tightened brake puts
unnecessary stress on the feeding mechanism and can cause the wire to
slip in the pulleys.
Figure 5 - Wire spool holder
ADJUSTING THE CLAMPING FORCE OF THE FEED PULLEYS
The amount of clamping force of the feed pulleys is important for the reliable
operation of the feeding mechanism.
The amount of force depends on the type of welding wire, for aluminium or
tubular wire we choose a smaller clamping force.
If the clamping force is insufficient, the pulleys slip and the feed rate becomes
irregular.
If the pressure 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 contaminated bovden, baked
wire in the grommet, etc.), the wire does not slip and there is a risk of the wire
being displaced to the side. In the extreme case, the motor may be completely
blocked and the gearbox will be unduly mechanically stressed, the electric motor
and the power output of the controller will be overloaded and may be damaged.
Clean the pulleys of canned oil before starting.

INTRODUCTION OF THE WELDING WIRE INTO THE TORCH AND
CONNECTION OF THE EARTHING CABLE
1. Connect the grounding pliers to the welding machine or welding table.
2. Caution Do not point the torch against the eyes when inserting the
wire!
3. Screw the central torch tip to the A3 connector on the machine with the
machine switched off.
4. Remove the gas nozzle from the Torch.
5. Unscrew the current feedthrough.
6. Connect the machine to the network.
7. Turn the main switch to position I.
8. Press button A13 located in the feed area of the machine to start the feed
motor. The welding wire is fed into the torch. After the wire has been run
out of the torch tube, screw on the current pass and the gas nozzle.
9. Before welding, spray the area in the gas nozzle and the jet line with a
separating spray to prevent spatter from sticking.
GAS FLOW ADJUSTMENT
The electric arc and the melt bath must be perfectly protected by gas. Too little
gas cannot create the necessary protective atmosphere; on the contrary, too
much gas entrains air into the electric arc.
Warning The gas cylinder must be well secured against falling. This
manual does not address the safe securing of the gas cylinder. Information can
be obtained from the supplier of industrial gases.
1. Attach the gas hose to the gland on the rear panel of the machine.
2. Press button V1 (fig. 7) on the main panel to switch on the gas valve. If the
button is pressed for less than 3 s, the gas valve will be switched off when
the button is released. If the button press time is longer than 3 s, the gas
valve will be switched off after approx. 20 s or after pressing any button.
3. Turn the adjusting screw F7 on the bottom of the pressure reducing valve
until the flow meter F6 shows the desired flow, then release the button.
The optimum flow rate is 10-15l/min.
4. After a prolonged machine shutdown or torch change, it is advisable to
purge the pipe with shielding gas before welding.

WATER TORCH COOLING SYSTEM
1. The cooling unit is located at the bottom of the machine.
2. The pump seal in this ALFA IN welder is specially designed for ACL-10
fluid (pink, order no. 4600, 5 l canister.
Operating range - ambient temperature -10 °C to +40 °C).
3. Leakage of the cooling circuit may occur if other fluids are used.
A failure of the cooling circuit using a fluid other than ACL-10 cannot be
covered under the manufacturer's warranty.
4. We recommend a complete fluid change every one to three years. The
fluid must not be mixed with any other type of fluid. The procedure for
changing the fluid can be found at
https://www.alfain.eu/static/_dokumenty/1/2/9/7/1/1/Vymena-chladici-
kapaliny1-navod-CZ.pdf
5. Keep the coolant level in the coolant reservoir
within the permitted range (see picture). The
fluid level is visually visible on the front of the
reservoir. Use the fluid prescribed by the
manufacturer.
If the error message "Err 2" - Low fluid
pressure lights up during operation, turn off
the main switch and check the coolant level.
After switching on the machine, test the cooling unit. If the error recurs, the
cause of the fault must be determined.
6. ACL-10 liquid is not poisonous. However, due to its operation in the pump,
treat the replaced fluid as hazardous waste. Do not pollute the
environment. In the worst case, take it to a salvage yard in its original
canister. The safety data sheet can be found at
https://www.alfain.eu/static/_dokumenty/1/2/8/8/0/4/Bezpecnostni-list-
ACL-10.pdf
7. Note: When connecting a gas-cooled torch, it is necessary to connect the
water quick couplings with the liquid circuit connection hose! Failure to do
so may result in damage to the pump.

16/33
ALFA IN a.s. © www.alfain.eu
VENTING OF THE TORCH COOLING SYSTEM
1. After filling an empty torch cooling system or after refilling the fluid after a
large leak and aeration, a complete venting of the circuit is required.
2. Remove the coolant reservoir cap and connect the water quick couplers
with the fluid circuit connecting hose.
3. Run the cooling test for about 30 seconds.
4. Connect the torch and run the cooling test for about 30 seconds.
5. If the error message "Err 2" - Low fluid pressure lights up after pressing
the torch button, the procedure must be repeated.
COOLING UNIT CONVERSION KIT

number is displayed on the right display V11.
2. Use encoder V16 to select the synergy curve (program number). Confirm
the selected program number by pressing encoder V5.
WELDING CIRCUIT CALIBRATION
The welding characteristics of the synergistic curve depend on many factors,
such as the length of the welding torch, the length of the grounding cable, the
quality of the grounding, the distance of the weldment from the grounding point,
etc. It is therefore advisable to calibrate the welding circuit for the actual welding
conditions.
1. Press button V20 and encoder V5 simultaneously to enter the secondary
parameters menu.
2. Select the CAL parameter with the V5 encoder, press to confirm
3. Set CrE with encoder V5, press to confirm.
4. Unscrew the gas nozzle of the welding torch.
5. Cut the welding wire close to the welding nozzle.
6. Pull a piece of welding wire (approx. 50 mm) into the wire feed. There must
now be no welding wire in the jet nozzle.
7. Apply slight pressure to the welding torch with the jet nozzle on a clean
and cleaned area of the workpiece, press the torch button and hold it down
for approx. 2 seconds. A short-circuit current flows for a while, by means
of which the new circuit resistance is determined and displayed. (The value
can be 0 mΩ to 60 mΩ - these values are not important for the user, factory
setting CrE = 10 mΩ, the value can be set badly with the V16 encoder).
8. If an error occurs, Err is displayed on the right display of V11, the
measurement must be repeated.

Works for all welding methods.
1. Long press (4s) of one of the V4 buttons (1,2,3,4,5,6) will save the set
parameters to the memory.
2. JOBs are stored as active (they can be switched by remote control on the
torch).
3. A short press of one of the V4 buttons (1,2,3,4,5,6) will retrieve the stored
parameters from memory.
4. If no JOB is stored for the desired position, the display will show No Job.
WELDING MODE 2T - TWO-STROKE
Works for both MIG/MAG welding methods.
Use the V20 button to switch between the 2T , 4T and modes.
If the V17 light is on, the machine is set to two-stroke mode. The first stroke is
to press the torch button and keep it pressed, the machine will start the welding
process. The second stroke means to release the torch button, the machine
stops the welding process.
WELDING MODE 4T - FOUR STROKE
Works for both MIG/MAG welding methods.
Use the V20 button to switch between 2T , 4T and modes. If
the V18 light is on, the machine is set to 4-stroke mode. The first stroke is to
press the torch button and keep it pressed, the machine will start the welding
process. The second stroke means to release the torch button, the machine
continues the welding process. The third stroke means to press the torch button,
the welding process continues. The fourth stroke means to release the torch
button, the machine stops the welding process.
WELDING MODE 2T - DOUBLE STAIRS
Works for both MIG/MAG welding methods (only in SYN mode).
Press the V20 button to switch between the 2T , 4T and
modes. If the V17 and V19 lights are on, the machine is set to two-stroke stair
mode. The first stroke means to press the torch button and keep it pressed, the
machine will start welding with the starting current SCu for the starting current t

S. Then the machine will start welding with the main welding current (100%) after
the start-up time tuP. The second stroke means to release the torch button, the
machine will start welding with the end current ECu for the end current t E after
the start-up time tdo.
WELDING MODE 4T - FOUR STAIRS
Works for both MIG/MAG welding methods.
Press the V20 button to switch between the 2T , 4T and
modes. If the V18 and V19 lights are on, the machine is set to the 4-stroke stair
mode. The first stroke is to press the torch button and keep the button pressed,
the machine will start welding with the starting current SCu. The second stroke
means to release the torch button, the machine will start welding with the main
welding current (100%) after the ramp-up time tuP. The third stroke means to
press the torch button, the machine will start welding with the end current ECu
after the ramp-down time tdo. The fourth stroke means to release the torch
button, the machine stops the welding process.
BILEVEL bCu ≠ 100 %
The difference of the BILEVELU compared to the classical steps is in the second
stroke, when by quickly pressing and releasing the torch button the machine
switches between the two set main welding currents.
