Abstract
A-1150U machine designed in 1960s is still in demand in its upgraded form in shipbuilding, bridge and storage tank construction. Pilot Plant of Welding Equipment of the E.O. Paton Electriс Welding Institute (PWI PPWE) developed a new control circuit based on modern components and control units. The new circuit provides substantial improvement of technical and service characteristics of the machine, and simplifies implementation of the welding process with forced weld formation. The machine with the new electric circuit is additionally designated by «K» index (A-1150K).
