Abstract:

This article,taking the tight fixing of the winding core of cable obstacle test set type-J6081 for example,introduces the technology replaced traditional riveting by hydrogenargon(A_r+H_2)gas mixture arc welding(non-melt pole),and expounds the main power circuit of welding machine type-ZXG300,welding current control system,the improving method of high frequency arc starting circuit and its principle.Besides,the effects of technique and economy for these two technologies is analyzed also,resulting in rational improvement and notable benefit.
