The semi-automatic welding process involves fusing the edges of the work piece and the consumable
electrode material with the heat of an electric arc glowing between the electrode in the form of a
solid wire and the welded part, in an inert or active gas shield.
The main protective gases used for MIG welding are inert gases such as argon, helium and MAG active
gases: CO2, H2, O2, N2 and NO, used separately or as additives to argon or helium.
The fusible electrode is in the form of a solid wire, usually 0.6 1.2 mm in diameter, and is fed in mm,
and is fed in m / min upwards. Welding torches can be cooled by liquid or shielding gas. Welding is
carried out mainly with direct current with positive polarity, as semiautomatic, mechanized welding,
direct current with positive polarity, as semi-automatic, mechanized, automatic or robotic welding
using specialized equipment. The shield of the welding arc glowing between the consumable
electrode and the material being welded ensures the formation of the weld under very favorable
thermal and chemical conditions. This type of welding can be used to make high-quality joints of all
metals that can be joined by arc welding. These include: carbon and low alloy steels as well as
corrosion resistant steels. Welding can be carried out in workshop and field conditions in all positions.
SINGLE PULSE MODE
MIG PULSE is an advanced form of welding that uses the best of the forms of the transfer of molten
electrode material to the work piece. Unlike short circuits, pulse welding does not produce spatter
and there is a risk of cold "leakage". Welding positions in the pulse are not limited because they are
derived from globular or spray forms, and their use is definitely more efficient. By cooling the spray
arc process, pulsed MIG is able to extend the welding range, and smaller heat input does not cause
a problem with burning thin materials. MIG PULSE is one of the best welding processes for a wide
range of applications and types of metal.
DOUBLE PULSE MODE
Welding with the MIG / MAG method with double pulse we get a high level of face appearance (husk
effect). In addition, the use of automatic wire feed affects welding performance. The MIG / MAG
method with double pulse allows the regulation of current pulsation (pulse balance) and adjustment
of the wire feed speed. Thanks to this, we improve the appearance of the weld. When MIG / MAG
welding with double pulse, current pulses occur in two ranges. The sequential system of our devices
automatically combines two levels of pulses.
