3. Put the inlet 11 onto the spool holder 10 followed by the spring and tighten
up the nut onto the holder 10 .
4. Cut off the curved or damaged end of welding wire and lead it through the
feeder inlet liner 12, and the roll 15 into the torch inlet liner 16 (about 5 cm).
Make sure, that you use the suitable groove of the roll.
5. Make sure that the wire fits into the torch inlet liner 16!
6. Put the pressure arm 14 down to side and fix it by setting the fixing shaft 13
into vertical position.
7. Adjust the pressure of the fixing shaft 13 that way that it provides constant
movement of wire but it does not deform wire.
INSERTING THE WELDING WIRE INTO THE WELDING TORCH
1. Take off the torch gas cup.
2. Take off the torch tip.
3. Press the torch trigger, the wire will start feeding into the torch.
4. When the wire reaches the end of the torch, release the trigger, screw on
the tip and the nozzle.
CHANGING THE WIRE FEEDER ROLL
Every wire feeding roll in ALFA IN machines can be used for two different
diameters of welding wire – the rolls have two grooves.
1. Open the wire feeder by means of the fixing shaft 13 .
2. Unscrew the plastic fixing cup 15 and take off the roll 15 .
3. In case there is suitable groove on the roll, turn it around and fix it back to
the feeder.

GAS FLOW SETTING
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.
