Description of the development:
()
The MIG welding voltage adjustment is carried out in steps (27 steps). Rectifiers can be used for vozdushnodugovoy gouging. A large supply of power allows to weld with a length of communications between the source and the power supply of more than 50 meters, which makes it ideal for assembly work, for example, with a supply unit "" PATON BP-315 "," Paton BP-600. "  The system of welding power in addition to the basic integrated parametric reactor, which can significantly improve the quality of the welded joints, due to the stabilization provided by the choke of the welding process and the regulation of short-circuit current (Isc), which occurs at the transition drops of molten metal from the electrode to the weld pool. In the main power windings typically use an auxiliary winding which serves to regulate the amount of inductance, and thus the peak current Isc in said transition. Auxiliary winding to reduce the time sc and reduce the droplet size of the molten metal, which improves the formation of the weld seam and provides a smooth surface thereof. An additional effect is achieved with the beginning of the auxiliary winding is connected via a diode to the electrode and its end - to the work piece. When short-circuit with the workpiece through the drop of molten metal is an increase in power winding current and increase current in the auxiliary winding, which are summed up, resulting in Isc sharply increased while reducing the time and increasing the frequency of repetition of the transition to the droplet electrode product. Metal transfer becomes atomized, reduced losses of electrode metal through burning and splashing, burning of alloying elements, reduced oxidation of the metal. Using parametric reactor not only improves the formation and quality of the weld, especially in thin metal welding, but also facilitates application of vertical and in-line joints. Can mnogopostovoy manual arc welding: VS650 for CP - 2 posts x 400A, 3 x 315A fasting, Lent 4 x 250A, 200A x 5 posts. For sun - 450 CP - 2posta 2 x 315 A, 3 x 250 A fast, 4-gang x 200 A. In this case, welding is at the maximum open-circuit voltage with separate adjustment of the welding current at each site using the Ballast resistor RB 302. Rectifiers are on the front panel of four separate outputs for manual metal arc welding (c / o RB-302) or multi-function welding using choppers.
