Electrode wire with shielding and negative pressure suction functions

The invention provides an electrode wire with shielding and negative pressure suction functions. The electrode wire comprises a main machine end connecting terminal, a movable middle baffle, a wire body, an electrode cup end connecting terminal and a removal air pipe. An air path is formed by a jacket, and the wire is small in diameter, good in flexibility and good in air tightness. 本发明提供了一种具屏蔽和负压抽吸功能的电极线，包括主机端连接端子，可移动中挡，线材主体，电极杯端连接端子，去除气管，由外被形成气路，线材直径小且柔韧性好，气密性好。
