It runs on DC+ or AC in all positions except vertical down, with 70 ksi minimum tensile strength. The H4R designation delivers up to 60% less moisture pickup than competitive E7018 electrodes, reducing the risk of hydrogen-induced cracking in code-quality fabrication.\u003c\/p\u003e\n  \u003cp\u003e\u003cstrong\u003e\u003ca href=\"https:\/\/weldingmart.com\/products\/lincoln-excalibur-7018-mr-stick-smaw-welding-rod\"\u003eSee all sizes of Lincoln Excalibur 7018 MR family\u003c\/a\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003c\/section\u003e\n\u003csection class=\"child-pdp-faq\"\u003e\n  \u003ch2\u003eQuestions about this package\u003c\/h2\u003e\n  \u003cdetails\u003e\n    \u003csummary\u003eIs this the same electrode as the parent Excalibur 7018 MR grade, just in a different package?\u003c\/summary\u003e\n    \u003cp\u003eYes. SKU ED033868 is the same AWS A5.1 E7018 H4R low-hydrogen electrode as every other size in the Excalibur 7018 MR family.

Once opened, rebake within 4 hours of exposure to ambient humidity or store in a heated rod oven at 250-300 F. Excalibur MR is moisture-resistant (H4R) and tolerates brief atmospheric exposure better than standard E7018, but rebaking restores full code performance.\u003c\/p\u003e\n  \u003c\/details\u003e\n  \u003cdetails\u003e\n    \u003csummary\u003eWhat diameter should I use for common code-quality structural work?\u003c\/summary\u003e\n    \u003cp\u003e3\/32 in is well-suited for root passes, thin material, and out-of-position work on light structural and pipe. Heavier base metal and higher deposition typically calls for 5\/32 in or 3\/16 in; thinner sheet and root passes use 3\/32 in. See the grade page for full diameter-to-amperage guidance.\u003c\/p\u003e\n  \u003c\/details\u003e\n  \u003cdetails\u003e\n    \u003csummary\u003eCan I mix this size with other diameters on the same job?\u003c\/summary\u003e\n    \u003cp\u003eYes, provided your procedure qualification (WPS) covers the range. Many shops use 3\/32 in for root, 1\/8 in for fill, and 5\/32 in or larger for cap and out-of-position passes. All sizes share identical mechanical properties (AWS E7018 H4R) so weld metal chemistry is consistent across passes.\u003c\/p\u003e\n  \u003c\/details\u003e\n  \u003cdetails\u003e\n    \u003csummary\u003eDo I need to rebake these after the can is opened?\u003c\/summary\u003e\n    \u003cp\u003eYes for code-quality work. Per AWS D1.1 and most pressure-vessel codes, low-hydrogen electrodes exposed to atmosphere beyond 4 hours must be rebaked at 500-800 F for 1-2 hours or stored in a heated rod oven at 250-300 F. Excalibur 7018 MR (H4R) provides extra moisture-pickup margin but rebaking is still required for code work.\u003c\/p\u003e\n  \u003c\/details\u003e\n  \u003cdetails\u003e\n    \u003csummary\u003eDoes this size require a special holder or stinger?\u003c\/summary\u003e\n    \u003cp\u003eUse an electrode holder rated for the amperage range above (70-110 A). Most general-purpose stinger holders (e.g. 300-500 A class) handle 3\/32 in Excalibur 7018 MR without issue. For sustained high-amperage runs on larger diameters, a 500 A or higher holder is recommended.\u003c\/p\u003e\n  \u003c\/details\u003e\n  \u003cdetails\u003e\n    \u003csummary\u003eIs this Buy America compliant?\u003c\/summary\u003e\n    \u003cp\u003eYes.
