‐ set power switch
18
on the rear panel of the source to position “I”;
‐ set the semiautomatic MIG/MAG welding mode by pressing the button
4
; the
modes switch over end‐around;
‐ use buttons
2
to set the required welding voltage;
- install the coil with the wire of the required diameter;
- lift up the pressure roller arm;
- lead the free end of the wire through the input channel
15
into the welding
torch;
- lower and clamp the welding wire between the rollers; the pressing force of the
rollers is written on a plastic handle; if there is no experience, then initially set to
the middle position (this is about 3);
- using buttons
8
, set the required wire feed speed;
- use button
7
to pull the wire through the entire channel and adjust the final
pressing force of the rollers according to the recommendations for
semiautomatic welding; at the same time, pay special attention to the force of
clamping the coil brake: the coil should be MINIMALLY-REQUIRED and easily
rotated, but spontaneous unwinding should not be observed;
‐ if necessary, additional functions of welding process can be adjusted—see a
changeover sequence in Clause 6.1.
Remember to supply shielding gas. In order to check its availability, a
button
10
is provided in the torch channel, at the moment of pressing which the
wire does not feed. If you are new to welding and do not have experience in
establishing optimum pressure for welding of a specific work piece, you can for the
first time set gas pressure above the optimum value ~0.2MPa: this will have a
minor effect on the process, only increase consumption of shielding gas. However,
follow general recommendations on semiautomatic welding in the future to save
gas. Start also with an average position of wire feeding speed controller on the
feeding machine (~ 6.0...8.0m/min.) and average source voltage (~19V) for any
diameter of installed wire (Ø0.6...1.2m). This configuration may be not optimal,
but, under condition of correct work, even wire feeding (without jerks) and correct
connection, this " feeding machine" combination shall be able to weld so
far. For better results, adjust the source voltage with buttons
2
and wire feeding
speed by pressing buttons
8
on the wire-feeding machine according to general
recommendations on semiautomatic welding. Remember that these parameters
are different for each specific application.
