ZX5-250 Crystal Thyratron Arc Welding Machine Improvement And Development

Question exists which in view of the old ZX5 - 250 arc welding machines, in combination with progress of production actual need, with the foundation of domestic and foreign similar electric welding machines, this article has carried on the detailed analysis comparison to the electric welding machine main circuit, and has carried on the design and the computation to the choice belt balancing resistor pair of counter- star type main circuit transformer and the balancing resistor, for the factory to provide the production basis. At the same time, to redesign and improve its control circuit, and completed the control circuit board design and made lithograph by using specialized cartography software Protel 99. Through to the electric circuit board examination which makes proved that, this electric circuit board satisfies the manual arc welding completely in the performance the request, also obviously surpasses the old control board, in the structure simply understands, is easy to maintain. After the improvement electric welding machine has the very high natural price ratio, suits the factory volume production.This article completes the work mainly includes several aspects: Elaborated from the requirement of hand arc welding to the question of designing arc welding power source should be considered, Carries on the analysis comparison to four kind of typical circuits, and carries on the computation for the factory production electric welding machine transformer and the balancing resistor, by provides the production basis; Makes the improvement and the design using the Protel 99 software to the control circuit board synchronizing circuit and the external characteristic electric circuit, completes the control circuit board making lithograph plates. Carries on the electrical examination to control circuit board each part, obtains conforms to the request profile and the data. To entire machine carries on the examination in the factory test panel, It proved that the improvement the electric welding machine satisfies the hand arc welding completely the request.
