but the stability of the welding process and the mixing of the weld pool will change. This is
a very important condition for the user to accurately estimate the amount of change in the
heat input to the weld pool, e.g., by comparing it with another main current without pulse
mode.
These parameters are set in different situations in different ways, according to the
welder ’ s requirements. See paragraph 6.1 to change the value of any function in the current
welding mode
5. METAL-ARC INERT-GAS WELDING/METAL ACTIVE GAS WELDING (MIG/MAG)
The unit can act as a source for semi-automatic welding, and it has the necessary
current-voltage characteristic at the output of the power terminals when switching to this
mode. Absolutely any independent wire feeder operating at a specific power supply voltage
of the built-in motor can serve as an external feed mechanism for wire feeding. For this
purpose, it must have its own power source, or be powered from the source voltage (this is
a lower priority option, since very rarely such systems have a good and stable wire feeding).
Caution! In the simplest case, carbon dioxide "CO2" is used as a shielding gas when
welding ferrous metals, and when welding aluminium, only inert gases such as argon “ Ar ” ,
sometimes helium “ He ” are suitable. For stainless and high-alloy steels, mixtures in various
proportions “ 80% Ar+20% CO2 ” are often used. Use of other gases is allowed only in
agreement with the equipment manufacturer.
The procedure for preparing for welding with solid wire:
- insert the ground terminal into the socket of the source B "-";
- attach the ground terminal to the workpiece;
- a pre-made power jumper with a cable cross-section of at least 25 mm

must be
connected to the socket of the source A "+", and the other end is connected to the power
terminal of the wire feeder, in each case it is individual, so it makes no sense to list all the
options;
- connect the torch to the wire feeder;
- install the reducing valve on a gas cylinder with shielding gas "CO2", "Ar" or "Ar+CO2";
- connect the gas hose to the gas cylinder reducing valve and the fitting on the wire feeder,
the connection method may be different;
- open the gas cylinder valve, check for air-tightness;
- connect the mains plug to the power supply;
