S113851-089 - Hobart 447A E6013 Stick Electrode 5/32 Inch 10lb Pack

Technical Overview of Hobart 447A E6013 Electrodes

The Hobart 447A is a high-performance Stick (SMAW) electrode designed to meet AWS E6013 specifications. Engineered for general purpose fabrication, this electrode is characterized by its "fast freeze" slag system, which rapidly solidifies the weld pool. This physical property makes the 447A exceptionally capable in bridging gaps and managing applications with poor fit-up, where maintaining a controllable puddle is critical. The electrode features a 5/32 inch (4 mm) diameter and is supplied in a durable 10 lb (4.5 kg) plastic pak, ensuring moisture resistance and storage stability.

Technically, the Hobart 447A is formulated to operate with a very stable arc across all standard polarities: Alternating Current (AC), Direct Current Electrode Negative (DCEN), and Direct Current Electrode Positive (DCEP). This universal compatibility allows it to be used with virtually any constant current welding power source, from industrial 3-phase machines to smaller, portable buzz boxes. The flux coating is designed to produce a smooth weld bead with fine ripples and a slag that is easily detachable, often self-releasing in optimal conditions. This reduces post-weld cleaning time and improves overall process efficiency.

The electrode is classified for all-position welding, including flat, horizontal, vertical-up, vertical-down, and overhead. The ability to weld vertical-down is particularly advantageous for sheet metal applications, allowing for faster travel speeds and reduced heat input, thereby minimizing distortion. The 447A is suitable for both single and multiple pass welds on mild steel substrates. Its mechanical properties and arc behavior make it a preferred choice for maintenance, repair, and operations (MRO) environments where base metal conditions may not be pristine.

In industrial settings, the Hobart 447A serves as a reliable solution for shaft build-up, machine part repair, and the construction of metal buildings. Its forgiving arc characteristics help mitigate common defects associated with manual welding, such as undercut or slag inclusions, provided proper technique is employed. The 447A represents a balance of ease-of-use and technical reliability for mild steel fabrication.
