- lower and clamp the welding wire between the rollers, the pressing force of the rollers is
specified on the plastic handle. If you are new to the procedure, then initially set it to the
middle position (for an approximate value of 3);
- use buttons 8 to set the required wire feed speed;
- using button 7 , pull the wire through the entire channel and adjust the final pressing force
of the rollers, according to the recommendations for MIG/MAG welding. Meanwhile, pay
special attention to the clamping force of the coil brake: the coil must be MINIMALLY
CLAMPED AS REQUIRED and rotate easily, but there should be no spontaneous
unwinding. CAUTION! If the coil brake mechanism is not assembled correctly, it may "self-
tighten" when the coil rotates, which, after a short time, will lead to a complete blocking of
the wire with disruption of the welding process. Please double-check before the first wire
threading;
- if necessary, you can adjust the additional functions of the welding process at the source
and the wire feeder (see paragraph 6.1 for the order of switching).
Do not forget about the supply of shielding gas! To check its availability in the torch
channel, there is button 9 : when pressed, the wire is not fed. If you are a beginner and have
no experience in setting the optimal pressure for welding a particular product, then at the
first time the gas pressure can be set higher than the optimal value of ~0.2 MPa. This will
have little effect on the process, only the shielding gas consumption will increase. But in the
future, to save money, follow the general recommendations for semi-automatic welding
operations. Also start with the average value of the wire feed speed (~ 4 ... 6 m/min) and the
average voltage at the source (~ 19V) for any diameter of the installed wire (Ø0.6 ... 1.2mm),
it may not be optimal, but the unit should already weld. To achieve the best result, you need
to adjust the voltage at the source with buttons
2 and the wire feed speed with buttons 8 on
the feed unit according to the general recommendations for carrying out the welding process
with semi-automatic units. Remember, these parameters are different for each specific case.
