This tool is a specialized marking implement used primarily in metalworking. It deposits a highly visible, opaque line onto metal surfaces, facilitating precision in layout and fabrication. The mark resists torch flames and abrasion better than many alternatives, offering welders a reliable means to indicate cut lines, weld points, and other critical measurements.
The utilization of this marking method significantly enhances accuracy and reduces errors in metal fabrication. Its durable mark survives exposure to high temperatures and rough handling, ensuring that crucial markings remain visible throughout the welding process. This reliability has made it a staple in welding shops and construction sites for decades, contributing to improved efficiency and reduced material waste.
