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.

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.
