S113844-045 - Hobart 447A E6013 1/8-Inch Stick Electrode 5lb Pack

Technical Overview of Hobart 447A E6013 Electrodes

The Hobart 447A is a premium quality Shielded Metal Arc Welding (SMAW) electrode designed to meet the AWS E6013 classification. Engineered for versatility and ease of use, this 1/8-inch (3.2 mm) diameter electrode is formulated with a rutile-based coating that facilitates a soft, steady arc and low spatter levels. It is specifically developed for the welding of mild steel substrates, offering robust performance across a variety of industrial and maintenance applications. The electrode is packaged in a durable 5 lb (2 kg) plastic pack, ensuring moisture resistance and long-term storage stability.

One of the defining technical characteristics of the Hobart 447A is its "fast freeze" slag system. This property allows the molten weld pool to solidify rapidly, making it an exceptional choice for bridging gaps in joints with poor fit-up. This characteristic is particularly beneficial in maintenance and repair operations where material preparation may not be optimal. Despite its fast-freezing nature, the electrode maintains a smooth bead profile with excellent tie-in at the toes of the weld, reducing the need for extensive post-weld grinding or cleanup.

The Hobart 447A is designed for all-position welding, including flat, horizontal, vertical-up, vertical-down, and overhead positions. This omni-directional capability allows operators to perform complex fabrication tasks without changing consumables. The electrode operates effectively on Alternating Current (AC), Direct Current Electrode Negative (DCEN), and Direct Current Electrode Positive (DCEP). This wide operating window ensures compatibility with a vast range of power sources, from industrial multi-process machines to smaller, entry-level buzz boxes. The 1/8-inch diameter is optimized for medium-gauge materials, providing sufficient deposition rates for structural work while remaining controllable enough for sheet metal applications.

Ideally suited for general purpose fabrication, the Hobart 447A excels in the construction of metal buildings, machine parts, and shaft build-up. Its ability to perform single or multiple pass welds adds to its utility in structural environments. The resulting weld deposits exhibit good mechanical properties consistent with the E6013 specification, ensuring structural integrity for non-critical mild steel applications. The slag is generally self-releasing or easily removable, further enhancing process efficiency.
