S112251-045 - Hobart 335A E6011 Stick Electrode 5/32" (5lb Plastic Pak)

Hobart 335A E6011 Stick Electrode: Technical Overview

The Hobart 335A is a premium cellulosic electrode designed to meet the rigorous demands of industrial fabrication and maintenance repair operations. Classified as an AWS E6011 electrode, this product is engineered to deliver deep penetrating characteristics, making it the electrode of choice when working with base metals that are not perfectly clean. Whether the substrate is galvanized, painted, rusty, or coated, the 335A digs through surface contaminants to establish a sound weld, significantly reducing the time and labor typically required for pre-weld cleaning and grinding.

While many cellulosic electrodes are notorious for unstable arcs, particularly on lower-cost power sources, the Hobart 335A is formulated to provide a stable arc with manageable spatter levels. It is optimized for Alternating Current (AC) power sources, which are common in many maintenance shops and field environments, but it performs equally well on Direct Current Electrode Positive (DCEP). This dual-polarity capability provides flexibility for welding operators working with varied equipment fleets. The electrode features a quick-freezing slag system, which is critical for controlling the weld puddle in out-of-position applications. This makes the 335A highly effective for vertical-up and overhead welding, ensuring that structural integrity is maintained regardless of the joint orientation.

The 5/32-inch (4.0 mm) diameter is suitable for welding heavier plate thicknesses where higher heat input and deposition rates are required. The product is supplied in a durable 5 lb (2 kg) plastic pack, which offers superior moisture resistance compared to traditional cardboard cartons. This packaging ensures that the cellulosic coating maintains its proper moisture content—crucial for generating the shielding gases that protect the arc—while preventing excessive moisture pickup that could lead to weld defects. Common applications for the Hobart 335A include shipbuilding, railcar fabrication, general structural work, and heavy equipment repair.
