Description

ARC INTERRUPTER {AN ARC INTERRUPTER}

The present invention relates to an arc blocking device, and more specifically, to an arc blocking device that can safely protect workers by blocking the arc flying from a welding torch during welding work from being emitted to the outside.

Generally, in shipyards, work is performed to fix multiple members or blocks made of steel to each other by welding them.

During this process, a large amount of welding arc was scattered around the worker, causing the problem that fire could occur in paint or materials sensitive to fire.

To solve this problem, work has traditionally been done by installing a blocking plate made of asbestos fabric to block the welding arc flying around the worker.

However, the blocking plate took up a lot of space, causing inconvenience to workers and pedestrians, and as the asbestos fabric of the blocking plate was damaged by the high-temperature welding arc and required periodic replacement, workers' workability was reduced and there was a risk of fire. come.

Accordingly, the need to develop technology that can block arcs from being emitted to the outside has been raised to prevent eye redness caused by arc light scattered from a welding torch, threatening safety.
