Welding is original, the striking is bright produces the electric current on the photosensitive induction sheet, it is bright stronger, the electric current is big more, the photosensor integration, apply at the electrothermal relay front end, two inside contact blades of electrothermal relay are owing to receive additional electric current heat impact and release naturally, then the power cut off, high definition digtal camera became invalid, simultaneously electrified welding lens camera does and transmits the video glasses inside with the image information in the safety cover, welding personnel can see clearly that the welding state operates, when welding completion or middle stop, electrothermal relay's two elastic contact blades cool off, reconversion, can carry out welding operation once more.

When the welding device is used, the welding rod extends into the caulking of the two tension springs, and the pulley moves forward and backward along the sliding rail in the 45-degree direction to complete welding.

Compared with the prior art, the invention has obvious advantages and beneficial effects. According to the technical scheme, the invention is applicable to shielded metal arc welding and carbon dioxide arc welding, and has the following characteristics:

1. and a weak current box is arranged above the protective cover, so that the lamp can illuminate and can prevent and control arc light.

2. A dense mesh wire mesh is arranged in the protective cover, so that the camera can be prevented from being damaged by splashing welding slag.

3. Slide rail, coaster are installed to the safety cover both sides, have two extension springs of embedding each other on the coaster, stretch into the caulking and weld along the horizontal direction in proper order when the welding rod, can effectively avoid electric arc light to reveal and hurt the human body.

4. The pulley can advance and retreat along the slide rail in 45 directions and weld, saves the welding rod to the utmost extent.

5. And a tension spring A is arranged between the pulley and the top end of the slide rail, so that the resetting is facilitated.
