If you notice a black area along the weld bead when using your Lincoln Electric Welding System, it could be due to several factors. First, the workpiece may have oily or organic contamination; make sure to clean it thoroughly. Second, the tungsten electrode might be contaminated; grind it to ensure it's clean. Third, inspect the gas line or torch connection for any leaks. Finally, check if the gas tank is running low and replace it if necessary.
