The Hobart Sterling AP 312 Stick Electrode is widely regarded as the "problem solver" for industrial maintenance and repair operations. When you are faced with a broken part and the exact composition of the base metal is unknown, or when you need to join two completely different types of steel, this is the electrode you reach for. Designed to handle the toughest welding challenges, the Sterling AP 312 provides a high-strength, ductile weld that resists cracking even under severe stress.
This 1/8" electrode is engineered for versatility. It performs exceptionally well in all positions—flat, horizontal, vertical, and overhead—making it indispensable for field repairs where positioning the workpiece is not an option. The "AP" in its name stands for All Position, and it lives up to that promise with a smooth, stable arc that is easy to control. Whether you are repairing heavy machinery, fixing a broken leaf spring, or fabricating a custom bracket from scrap steel, the Hobart Sterling AP 312 ensures a reliable bond.
One of the standout features of this product is its user-friendly performance. It operates on both AC and DCEP currents, making it compatible with a wide range of welding machines, from simple buzz boxes to advanced industrial power sources. The slag is self-detaching in many cases, or easily removed with a light chip, leaving behind a clean, professional-looking bead. For maintenance shops, having a can of Hobart Sterling AP 312 on the shelf means you are prepared for the unexpected, reducing downtime and keeping your operations running smoothly.
