OVERVIEW

Premium Hobart 718MC E7018 Stick Electrodes for Critical Applications

The Hobart 718MC 1/8" Stick Electrode is a high-performance, low-hydrogen consumable designed to meet the rigorous demands of heavy industrial fabrication. Engineered with a specialized coating that offers exceptional moisture resistance, this electrode significantly reduces the risk of hydrogen-induced cracking, making it a preferred choice for critical code work and structural applications. The "MC" designation highlights its superior moisture control characteristics, ensuring that the electrode maintains its low-hydrogen status (H4R) even after exposure to humid environments for extended periods compared to standard electrodes.

Industrial professionals rely on the Hobart 718MC for its outstanding mechanical properties, particularly in low-temperature environments where impact toughness is crucial. This electrode delivers X-ray quality weld deposits, ensuring compliance with stringent industry standards such as those found in shipbuilding, boiler construction, and offshore rig fabrication. The addition of iron powder to the coating enhances deposition rates, allowing for faster travel speeds and increased productivity without compromising the integrity of the weld. This makes it an economically efficient solution for large-scale projects requiring substantial metal fill.

Versatility is a key strength of the Hobart 718MC. It operates smoothly on both Direct Current Electrode Positive (DCEP) and Alternating Current (AC), providing flexibility for various power sources and field conditions. Its all-position capability allows welders to perform high-quality vertical and overhead welds with ease. The stable arc and fluid puddle control contribute to a flat, consistent bead profile with minimal spatter. Furthermore, the slag system is designed for easy removal, often peeling away on its own, which reduces inter-pass cleaning time and improves overall workflow efficiency.

Packaged in a durable 50lb can, these electrodes are protected during transport and storage, ensuring they arrive ready for immediate use. Whether you are welding low alloy structural steels, free machining steels, or high carbon steels, the Hobart 718MC provides the reliability and performance necessary for heavy-duty MRO and construction tasks. It is an essential consumable for sectors including petrochemical plants, power generation, and railroad locomotive construction.

FAQ

The Hobart 718MC is classified as an AWS E7018 electrode, typically meeting E7018 H4R standards for low hydrogen content and moisture resistance.

Hobart 718MC electrodes can be used with both Direct Current Electrode Positive (DCEP) and Alternating Current (AC).

As a low-hydrogen E7018 electrode, it is highly recommended to store open containers in a rod oven to maintain their low-hydrogen properties and prevent moisture pickup.

The 'MC' stands for moisture control; these rods have a specially formulated coating that resists moisture absorption better than standard E7018 rods and offers improved deposition rates.

Yes, the Hobart 718MC is an all-position electrode, making it suitable for flat, horizontal, vertical, and overhead welding.

This package contains 1/8 inch (approximately 3.2mm) diameter electrodes.

It is suitable for welding carbon steels, low alloy structural steels, free machining steels, and enameling steels.

Yes, Hobart 718MC is known for its excellent slag release, which often peels off easily, reducing cleanup time.
