OVERVIEW

The Rod That Does the Work for You

If you have ever struggled with 7018 rods that stick, fingernail, or refuse to restart, the Lincoln Excalibur 7018-1 MR will change your perspective on stick welding. Known among professional welders as one of the smoothest running rods in the industry, the Excalibur series is designed to make your life easier, whether you are welding flat, vertical-up, or overhead. The arc is soft yet penetrating, giving you a clear view of the puddle so you can stack dimes with precision.

One of the standout features of this rod is its puddle control. In vertical-up applications, the shelf builds effortlessly, allowing you to carry a consistent bead without fighting gravity. The coating burns off squarely, preventing the annoying "fingernailing" or side-arcing that plagues cheaper electrodes. When you finish a pass, you will appreciate the slag release; in many cases, the slag curls up and peels off on its own as it cools, leaving a shiny, clean bead underneath. This means less time chipping and wire wheeling, and more time burning rods.

Restriking a 7018 can often be a headache due to the non-conductive flux coating forming a hard shell over the tip. Lincoln has optimized the tip chemistry of the Excalibur 7018-1 to improve strike and re-strike performance, reducing the likelihood of porosity at the start of the weld. Whether you are repairing heavy equipment in the field or welding pipe in the shop, this 1/8" rod runs smooth on DC+ and handles AC machines surprisingly well, making it a go-to for almost any mild steel job that demands strength and reliability.

FAQ

MR stands for 'Moisture Resistant'. This indicates that the electrode's coating is formulated to resist absorbing atmospheric moisture, which helps maintain low hydrogen levels and prevents weld cracking.

The recommended amperage range is typically between 110 and 160 amps. For vertical and overhead positions, you generally run on the lower end (110-130A), while flat positions can handle the higher end.

Yes. As a low-hydrogen electrode, once the hermetically sealed can is opened, the rods should be stored in a holding oven at 250°F-300°F to maintain their low-hydrogen status.

Yes, Lincoln Excalibur 7018-1 MR is designed to operate smoothly on both DCEP (Direct Current Electrode Positive) and AC (Alternating Current).

The '-1' suffix indicates that the electrode meets specific impact toughness requirements at lower temperatures. E7018-1 is tested to provide impact resistance at -45°C (-50°F), whereas standard E7018 is tested at -29°C (-20°F).

No, E7018 electrodes are designed for vertical-up welding. Attempting to weld vertical-down will likely result in slag entrapment and lack of fusion.

This SKU corresponds to a 50 lb (22.7 kg) Easy Open Can.

The chemical composition of the flux is designed to have a different thermal expansion rate than the cooling metal, causing it to detach or 'curl' as the weld cools, provided the parameters and travel speed were correct.
