    • An arc ignition device of a plasma welding gun includes an igniter and a fixture. The igniter includes an arc ignition block (5), a spring (6) and a tungsten needle (3), and the fixture includes a fastening member (4), a tungsten needle clamp (7), a base (2) and a magnet (1). The arc ignition block and the tungsten needle are conductors. And the tungsten needle is clamped by the fixture with the fastening member cooperated with an arc surface of the tungsten needle clamp. Additionally, the magnet is embedded in the base, by means of which the arc ignition device can be attached to any position. Through the precise relative motion of the spring, the arc ignition device implements a high-requirement arc ignition function.
    • 等离子体焊枪的电弧点火装置包括点火器和固定装置。 点火器包括弧形点火块(5),弹簧(6)和钨针(3),并且该固定装置包括紧固构件(4),钨针夹具(7),基座(2)和 磁铁(1)。 电弧点火块和钨针是导体。 并且钨针被夹具固定,紧固件与钨针夹的弧形表面配合。 此外,磁体嵌入在基座中,借助于此,电弧点火装置可以附接到任何位置。 通过弹簧的精确相对运动,电弧点火装置实现了高要求的电弧点火功能。
