Can resistance welding be a possible cause of welder's flash?

Response to Resistance Weding and Welder's Flash

Dear Mr. Tan

I believe you are referring to the bright light emitted when arc welding in comparison with the sparks and light emitted during the resistance welding process. Resistance welding may cause expulsion of metals at either the start or end of the weld current sequence. This is molten metal that is been expelled due to the electronic forces during the weld cycle. Since this is molten metal, it will burn whatever it comes in contact with. Most cases this produces just pin hole type burns in clothing, or mild spot burns on the skin. These sparks definitely are a risk to eyesight. However the actual light emitted during the weld sequence will not produce the “Welder’s Flash” associated with the arc welding processes.
