Products for aiding welding or high temperature cutting operations comprise a work piece marker and a welding or cutting aid system. The marker includes a luminescent material which is excited by UV radiation generated during arc welding to emit light in the visible spectrum, e.g. orange light. The aid system includes a light filter matched to the visible emission wavelength of the marker interposed in the light path, adjacent the dark filter of a welder's mask. The marker is used to mark a weld or cutting path trace visible to the welder during the operation. A method of aiding a welding or cutting operation using the marker and matched light filter is also provided.
