OVERVIEW

Experience the Difference with Hobart 7018 XLM

For professional welders who demand consistency and ease of use, the Hobart 7018 XLM 3/16" stick electrode is a game-changer. We know that fighting a difficult puddle or dealing with stubborn slag can turn a long day into an exhausting one. That's why Hobart designed the XLM (Extra Low Moisture) series to not only meet code requirements but to provide superior "operator appeal." Whether you are welding heavy structural beams, repairing heavy equipment, or working on a ship deck, this rod runs smooth and keeps you moving.

The first thing you'll notice is the quiet, stable arc. It doesn't sputter or wander, giving you precise control over the weld puddle. This is especially important when you are welding out of position. Vertical-up welds lay down flat and consistent, without the excessive crowning or sagging that lesser rods might produce. The 3/16" diameter is perfect for filling large joints quickly, thanks to the iron powder in the coating that boosts your deposition rate. You get more metal down in less time, with fewer rod changes.

One of the biggest headaches in stick welding is slag removal. Hobart 7018 XLM features a slag system that cools and contracts rapidly, often peeling off by itself or requiring just a light tap with your chipping hammer. This means less time grinding and brushing, and more time burning rods. The restrike capability is also top-notch. If you need to stop and restart, or if you are tacking up a large assembly, the end of the rod doesn't glaze over instantly, allowing for easier arc initiation without sticking.

This 50lb can is the industry standard for shop use. The hermetic seal ensures that when you crack the lid, the rods are factory-fresh and ready to perform. Whether you are running an old buzz box on AC or a modern inverter on DC+, the Hobart 7018 XLM adapts to your machine to deliver professional, X-ray quality results every time.

FAQ

XLM stands for 'Extra Low Moisture'. This designation indicates that the electrode coating is formulated to resist moisture absorption from the atmosphere, which is critical for preventing hydrogen-induced cracking in the weld.

For a 3/16" diameter 7018 electrode, the typical amperage range is between 150 and 230 Amps. However, you should always fine-tune the settings based on your specific machine, welding position, and material thickness.

Yes, once the hermetically sealed can is opened, E7018 electrodes should be stored in a rod oven at temperatures between 250°F and 300°F (120°C - 150°C) to maintain their low hydrogen status and prevent moisture pickup.

Yes, these electrodes are designed to operate on both AC (Alternating Current) and DCEP (Direct Current Electrode Positive). They provide a stable arc on AC, which is helpful if your machine does not have DC capability or to prevent arc blow.

No, E7018 electrodes are designed for vertical-up welding. The slag is too heavy and fluid to support a vertical-down progression, which would likely result in slag inclusions and poor fusion.

This specific SKU is widely used in heavy industrial sectors such as shipbuilding, offshore construction, power plant maintenance, and structural steel erection due to its reliability and mechanical properties.

The iron powder in the coating melts along with the core wire, adding extra metal to the weld pool. This increases the deposition rate, allowing you to weld faster and fill joints more efficiently compared to non-iron powder rods.
