Plasma arc technology based digital multifunctional power supply

Abstract

A plasma arc technology based digital multifunctional power supply comprises a plasma arc welding power supply, wherein the plasma arc welding power supply comprises a rack, and a separating plate which is arranged in the rack; the separating plate is divided into an upper separating plate layer and a lower separating plate layer; the inner part of the plasma arc welding power supply is divided into a power supply control assembly, a welding output control assembly and a display operation assembly. The plasma arc technology based digital multifunctional power supply is stable in structure, andreasonable in space utilization; a workpiece is arranged between a plasma welding gun and an argon arc welding gun; the electric arc of argon arc welding and plasma welding can be changed; welding wires are heated and smelted through plasma arc and argon arc during being welded, and molten melt droplets are formed and enter a molten melt smelting pool on the workpiece, so that the welding smelting depth and the welding speed can be greatly increased, and the splashing is controlled; a main control board for controlling realizes power supply control; and the plasma arc technology based digitalmultifunctional power supply has the characteristics of being high in efficiency, small in loss, and wide in applicable scope.
