S112232-089 - Hobart 335A E6011 Stick Electrodes 3/32" 10lb Pack

Hobart 335A E6011 Cellulosic Stick Electrodes

The Hobart 335A is a premium cellulosic coated electrode classified under AWS E6011 standards. Designed specifically to offer superior performance on alternating current (AC) power sources, this electrode bridges the gap for operators who require the deep penetrating characteristics of an E6010 but are limited to AC welding machines. While optimized for AC, it retains full compatibility with Direct Current Electrode Positive (DCEP), offering versatility across various equipment setups. The 3/32-inch diameter configuration in this 10 lb pack is ideal for thinner gauge materials and precise root passes in pipe and plate welding.

Technical Performance and Arc Characteristics

Engineered for aggressive fusion, the Hobart 335A delivers a forceful, digging arc that effectively cuts through surface contaminants. This makes it the electrode of choice for maintenance and repair operations (MRO) where base metal preparation is difficult or impossible. The arc stability is notably superior to standard E6011 electrodes, reducing the likelihood of arc outages and sticking, which are common challenges with cellulosic rods on AC power. The quick-freezing slag system supports all-position welding, including difficult vertical-up and overhead joints, allowing for rapid travel speeds and efficient bead contour control.

Material Compatibility and Applications

This electrode excels in applications involving coated or degraded steels. It is particularly effective on galvanized steel, where its penetrating arc burns through the zinc coating to establish a sound weld, minimizing porosity and inclusions. It is also highly recommended for welding on painted, rusty, or greasy mild steel surfaces commonly found in agricultural equipment, structural rehabilitation, and general fabrication. The mechanical properties meet AWS A5.1 requirements, ensuring structural integrity for non-critical and semi-critical applications in shipbuilding, railcar repair, and general construction.

Operational Advantages

The Hobart 335A distinguishes itself with lower spatter levels compared to generic E6011 rods, resulting in less post-weld cleanup. Its ability to handle poor fit-up and bridge gaps makes it an indispensable tool for field repairs. The 10 lb packaging provides a convenient quantity for medium-scale projects or shop inventory, ensuring electrodes are available when challenging conditions demand a robust, penetrating solution.
