怎样使用二氧焊?
二氧化碳气体保护焊？？？
那个就是 一个焊机 一卷焊丝 跟一个二氧化碳气瓶 ~~~
打开 二氧化碳气瓶
顶好顶针 就是压力管下边的那个小黑色旋钮 然后 根据 焊件调节好电流 电压~~ 焊枪中间 对准 焊件 缝隙的中间 既 焊丝要在焊缝中间 然后按下 焊枪上的 按钮式 开关~~ 拖着焊就是 一般 焊 平焊 都是采用 左焊法 就是 右手拿 焊枪 往左边跑 ~~~ 这样可以看清楚 焊缝~~ 还有 就是 最好 工件 一边高 一边底
⑴在点火前，必须做好以下3项检查：
A. 先打开乙炔瓶阀，看压力表指针是否在规定压力范围内。
B. 再打开氧气瓶阀，看压力表指针是否在规定压力范围内。
当然是 2保焊焊接性能要好咯
手工焊 优点 造价便宜 重量轻 设备简单 可以说 整个就是一个变器
缺点 当然对人的操作需求大 不容易 实现 机械...
二氧化碳保护焊操作技术
二氧化碳气体保护焊熔深大，没有焊渣，生产率高，既可焊薄板，又可焊厚板，适应性强，焊接后焊件变形...
