High-frequency triggered direct-current welding power source

Abstract

Herein The invention discloses a high-frequency triggered direct-current welding power source, and belongs to the technical field of welding equipment. The high-frequency triggered direct-current welding power source comprises an outer protection sound insulation component, wherein a heat dissipation component is arranged in the outer protection sound insulation component, and the heat dissipation component is used for generating air vortexes. According to the high-frequency triggered direct-current welding power source, through mutual cooperation of the designed structures such as the outer protection sound insulation component, the energy conversion component, the heat dissipation component and an air flow filtering component, air sprayed out of a spiral pipe can enter a direct-current arc welding power source case in a spiral shape, the radiation range of low-temperature air is enlarged, and in addition, heat in cracks of electronic components in the direct-current arc welding power source case can be quickly dissipated by means of attraction force generated by the spiral air flow. Therefore, the heat dissipation effect is further improved, energy recovery is conducted in the whole stroke of vibration, waste energy utilization is facilitated, and the shock resistance of the direct-current arc welding power source is further improved.
