S113244-031 - Hobart Deckmaster 1139 E6022 1/8" Stick Electrodes 50lb Carton

Hobart Deckmaster 1139 E6022 Stick Electrode Overview

The Hobart Deckmaster 1139 is a specialized Shielded Metal Arc Welding (SMAW) electrode designed to meet the rigorous demands of the construction industry, specifically for roof decking applications. Classified under AWS E6022, this electrode is engineered to provide deep penetration and reliable fusion even under less-than-ideal surface conditions. It is supplied in a heavy-duty 50 lb (22.7 kg) carton, ensuring ample supply for large-scale structural projects.

One of the defining technical characteristics of the Deckmaster 1139 is its ability to perform burn-through spot welds with full penetration. This is critical when securing roof decking to support beams, where the integrity of the connection is paramount. The electrode's flux formulation is chemically active, allowing it to weld directly through surface contaminants such as galvanization, paint, primer, plating, and general dirt. This capability significantly reduces pre-weld preparation time, thereby increasing overall job site productivity.

The electrode features a 1/8 inch (3.2 mm) diameter and offers exceptional versatility regarding power source compatibility. It operates stably on Direct Current Electrode Negative (DCEN), Direct Current Electrode Positive (DCEP), and Alternating Current (AC). This flexibility ensures that the Deckmaster 1139 can be utilized with a wide range of welding machines commonly found on construction sites. Furthermore, the electrode is optimized for specific welding positions, delivering superior performance in Flat, Horizontal, and Vertical Down orientations. This makes it particularly effective for rapid downhill welding on light gauge materials, where travel speed and bead profile control are essential.

In summary, the Hobart Deckmaster 1139 represents a targeted solution for structural steel decking. Its compliance with industry standards, combined with its robust performance on coated steels and light gauge sheets, makes it an indispensable consumable for professional ironworkers and construction welding teams requiring consistent, high-quality results in single-pass applications.
