For professional welders, the "feel" of the rod is everything. The Lincoln Excalibur 7018-1 MR (2.5mm) is legendary in the industry for a reason: it runs smoother than almost any other 7018 on the market. If you are tired of fighting with rods that fingernail, stick, or have hard-to-remove slag, switching to Excalibur will feel like an upgrade to your entire setup. This electrode is designed to burn off squarely, giving you exceptional directional control and a focused arc that puts the metal exactly where you want it.
The "MR" stands for Moisture Resistant, but for the welder, it translates to a rod that starts easy and restarts even easier. The coating is flexible enough to resist cracking when you bend the rod for those tight, awkward positions, yet durable enough to maintain a stable arc column. The slag system is formulated to lift easily—often peeling up by itself as it cools—leaving behind a clean, smooth bead profile that requires minimal post-weld grinding or brushing. This is crucial when you are welding out of position, such as vertical-up or overhead, where slag entrapment can be a nightmare with lesser rods.
This 2.5mm (approx. 3/32") version is perfect for root passes in pipe welding or for fabricating thinner walled structural tubing where heat input control is critical. It offers excellent impact toughness at low temperatures, making it a reliable choice for field work in harsh climates. Whether you are welding on a bridge, a pressure vessel, or a heavy equipment repair, the Excalibur 7018-1 MR gives you the confidence that your welds will pass X-ray and ultrasonic testing every time.
