一种附有空心钨极的熔化极气体保护焊焊枪
摘要：
一种附有空心钨极的熔化极气体保护焊焊枪，包括枪体和从枪体内穿过的焊丝(1)以及输送焊丝(1)的送丝系统(2)，其中枪体末端为喷嘴(3)，枪体内装设有导电嘴(4)，在导电嘴(4)末端连接有空心钨极(5)，从枪体内穿过的焊丝(1)穿过导电嘴(4)和空心钨极(5)，焊丝(1)末端伸出喷嘴(3)一段距离。本发明的焊接电弧更加稳定，焊接质量和焊接效率都更高。该焊枪构造合理，维护方便。
摘要（英）：

A gas metal arc welding gun with a hollow tungsten electrode comprises a gun body, a welding wire (1) penetrating through the gun body and a wire feeding system (2) for conveying the welding wire (1). A nozzle (3) is arranged at the tail end of the gun body, and a conducting nozzle (4) is mounted in the gun body; the hollow tungsten electrode (5) is connected to the tail end of the conducting nozzle (4), and the welding wire (1) penetrating through the gun body penetrates through the conducting nozzle (4) and the hollow tungsten electrode (5); the tail end of the welding wire (1) extends out of the nozzle (3) by a certain distance. According to the gas metal arc welding gun, a welding electric arc is more stable, and the welding quality and the welding efficiency are both higher. The welding gun is reasonable in structure and convenient to maintain.
