OVERVIEW

The Rod That Burns Like a Dream

If you have ever fought with a stick rod that fingernails, sticks on restarts, or drops slag that just won't chip off, you know the value of a premium consumable. The Lincoln Excalibur® 7018-1 MR® is widely regarded by professional welders as one of the smoothest running 7018 rods on the market. Designed for the welder who cares about bead appearance and ease of operation, this 1/8-inch rod delivers a buttery smooth arc that stays stable even when you are forced into uncomfortable positions. Whether you are welding vertical-up on a column or overhead on a pipe rack, the puddle control is exceptional.

One of the biggest frustrations in stick welding is slag removal. Excalibur rods are famous for their slag release; in many cases, the slag will curl up and peel off by itself as the weld cools, leaving a clean, shiny bead underneath. This saves you time on cleanup and grinding, letting you move on to the next pass faster. The coating is also incredibly durable. You can bend this rod to get around a tight corner or into a difficult joint, and the flux won't pop or flake off like cheaper alternatives. This flexibility ensures you maintain shielding gas coverage right to the end of the burn.

Restarts are another area where the ED032592 shines. The tip design and coating formulation allow for easy restriking without the rod sticking to the work, reducing the chance of porosity at the start of your bead. Because it is an MR (Moisture Resistant) rod, it stays fresh longer once the can is cracked open, giving you confidence that your welds will pass X-ray and ultrasonic testing. When the job calls for code-quality welds and you want a rod that works with you rather than against you, reach for the Excalibur.

Why Welders Choose Excalibur

  • Easy Slag Removal: Often self-peeling, reducing cleanup time.
  • Bendable Coating: Flux stays intact even when the rod is bent for tight access.
  • Smooth Arc: Minimal spatter and consistent burn-off.
  • All-Position Master: Excellent puddle control in vertical and overhead positions.
  • Reliable Restarts: Less sticking and porosity at the tie-in.

FAQ

The '-1' suffix indicates improved impact toughness. E7018-1 electrodes, like this Excalibur model, are tested to provide specific impact properties at lower temperatures (-50°F) compared to standard E7018 (-20°F), making them suitable for more critical applications.

Q2 Lot® is Lincoln Electric's verification system where the actual chemical composition and mechanical properties of the electrode lot are tested and certified. This ensures the product meets specific requirements for critical code work.

For a 1/8" (3.2mm) Excalibur 7018-1, the recommended amperage range is typically between 90 and 160 amps. For vertical and overhead positions, you generally run on the lower end of that range (around 110-125A).

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 and prevent moisture absorption.

Yes, Excalibur 7018-1 MR is designed to operate on both DC+ (Reverse Polarity) and AC current, providing flexibility depending on your power source.

Yes, this specific SKU (ED032592) complies with the chemical composition recommendations of API 751 for HF alkylation service.

MR stands for Moisture Resistant. It indicates that the electrode coating is formulated to resist absorbing moisture from the air, which helps prevent hydrogen cracking in the finished weld.

The coating is designed to be flexible so that welders can bend the electrode to access tight or obstructed joints without the flux cracking or falling off, ensuring proper shielding is maintained.
