The invention relates to the technical field of plasma guns, in particular to a double-arc plasma gun with an internal powder feeding function. According to the double-arc plasma gun, an upper nozzle and a lower nozzle are installed in a double-pole mode, communicated with a positive electrode of a power source and matched with a double negative electrode connected to a steel pipe and a tungsten electrode, double-arc welding is achieved, the muzzle temperature is increased, and the powder particle melting degree is increased; and the powder sent out from the inclined powder channel is directly subjected to arc striking at the tungsten electrode, the arc striking effect is better, arc breaking and arc deflection are greatly reduced, efficient cooling is achieved through the large-area circulating cooling pipeline, the using effect of the plasma gun is improved, and the service life of the plasma gun is prolonged. 本发明涉及等离子枪技术领域，特别是涉及一种具有内送粉功能的双弧等离子枪，本发明通过上喷嘴与下喷嘴的双极安装，与电源正极连通，并与连接在钢管的上的双重负极与钨极配合实现双弧焊接提高枪口温度，提高粉体
