The Lincoln Electric E6013 Fleetweld Welding Stick Electrode, 5lb, 1/8 x 14-in, 20-Pk, is designed to produce high-quality welds on carbon steel. Each 20-pack of Fleetweld 37 electrodes offers consistent performance to help tack and fill welds, making them a handy addition to any fabrication toolbox. The 1/8-inch diameter rod is ideal for welding thicker materials up to 3/8 inch and the 14-inch length allows for a good amount of welding time before requiring a new rod. While simple to use, the electrodes produce welds with excellent tensile and yield strengths suitable for many structural and mechanical applications.
