OVERVIEW

Reliable All-Position Welding with Hobart 718

When your job demands a weld that is as tough as it is clean, reach for the Hobart 718 3/32" Stick Electrode. Known in the industry for its smooth running characteristics, this rod is a go-to for professional welders tackling structural steel, bridge work, or heavy equipment repair. The 50 lb can is perfect for shop environments or large field projects where volume and consistency are key. Whether you are welding in the flat, horizontal, vertical, or overhead position, the Hobart 718 gives you the control you need to lay down a perfect bead every time.

One of the biggest frustrations with stick welding is fighting the slag. Hobart has formulated the 718 to have exceptional slag release—in many cases, it simply lifts off as the weld cools, saving you time with the chipping hammer and wire brush. The arc is stable and predictable, with low spatter levels that keep your workpiece clean. Because it is an E7018 rod, it provides the low-hydrogen properties essential for preventing cold cracking, especially when working on thicker sections or restrained joints.

This rod runs beautifully on DCEP, giving you deep penetration and fusion, but it is also formulated to run smoothly on AC welders, preventing arc blow issues often encountered in corners or complex joints. The 3/32" size is an excellent all-rounder, small enough for detailed passes but capable of handling multi-pass structural welds. If you are looking for a rod that makes you look good and passes X-ray inspection with ease, the Hobart 718 is the professional's choice.

FAQ

Hobart 718 is designed to operate on DCEP (Direct Current Electrode Positive) or AC (Alternating Current). DCEP is generally preferred for smoother arc characteristics.

The H4R designation indicates that the electrode meets specific moisture resistance tests (less than 0.4% moisture absorption) and diffusible hydrogen limits (less than 4ml per 100g of weld metal), reducing the risk of hydrogen-induced cracking.

Yes, once the hermetically sealed can is opened, E7018 electrodes should be stored in a rod oven at 250°F-300°F to maintain their low-hydrogen status. If exposed to air for too long, they may need re-baking.

For the 3/32" diameter Hobart 718, the recommended amperage range is typically between 70 and 110 Amps, depending on the welding position and base metal thickness.

No, E7018 electrodes like the Hobart 718 are designed for vertical-up welding. They have a heavy slag that will trap if used vertical-down.

E7018 rods are sensitive to contaminants. While they can handle minor mill scale, it is highly recommended to clean the base metal of rust, oil, and paint to prevent porosity and hydrogen cracking.

The Hobart 718 produces a weld deposit with a minimum tensile strength of 70,000 PSI, meeting AWS A5.1 requirements.
