The XMR designation indicates an enhanced moisture-resistant coating beyond the standard MR (Moisture Resistant) designation, providing the most extended out-of-oven exposure time allowed while still meeting H4 hydrogen performance (≤4 mL\/100g diffusible hydrogen). The 3\/32 in (2.4 mm) diameter is the smallest commonly stocked Excalibur 7018 diameter, designed for root pass welding, thin-plate applications, restricted-access joints, and vertical and overhead position work where smaller rod diameter provides better operator control. This combination of 3\/32 diameter, H4R performance, and XMR moisture resistance makes this the most demanding field conditions electrode in the Excalibur 7018 size range.\u003c\/p\u003e\u003ch2\u003eAWS Classification \u0026amp; Specifications\u003c\/h2\u003e\u003ctable style=\"min-width: 50px\"\u003e\n\u003ccolgroup\u003e\n\u003ccol style=\"min-width: 25px\"\u003e\n\u003ccol style=\"min-width: 25px\"\u003e\n\u003c\/colgroup\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth colspan=\"1\" rowspan=\"1\"\u003e\u003cp\u003eAWS classification\u003c\/p\u003e\u003c\/th\u003e\n\u003ctd colspan=\"1\" rowspan=\"1\"\u003e\u003cp\u003eAWS A5.1\/A5.1M E7018 H4R\u003c\/p\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth colspan=\"1\" rowspan=\"1\"\u003e\u003cp\u003eLincoln designation\u003c\/p\u003e\u003c\/th\u003e\n\u003ctd colspan=\"1\" rowspan=\"1\"\u003e\u003cp\u003eExcalibur 7018 XMR (Extra Moisture Resistant)\u003c\/p\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth colspan=\"1\" rowspan=\"1\"\u003e\u003cp\u003eCoating type\u003c\/p\u003e\u003c\/th\u003e\n\u003ctd colspan=\"1\" rowspan=\"1\"\u003e\u003cp\u003eIron powder \/ low-hydrogen (extra moisture-resistant)\u003c\/p\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth colspan=\"1\" rowspan=\"1\"\u003e\u003cp\u003eRod diameter\u003c\/p\u003e\u003c\/th\u003e\n\u003ctd colspan=\"1\" rowspan=\"1\"\u003e\u003cp\u003e3\/32 in (2.4 mm)\u003c\/p\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth colspan=\"1\" rowspan=\"1\"\u003e\u003cp\u003eRod length\u003c\/p\u003e\u003c\/th\u003e\n\u003ctd colspan=\"1\" rowspan=\"1\"\u003e\u003cp\u003e14 in (356 mm)\u003c\/p\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth colspan=\"1\" rowspan=\"1\"\u003e\u003cp\u003ePolarity\u003c\/p\u003e\u003c\/th\u003e\n\u003ctd colspan=\"1\" rowspan=\"1\"\u003e\u003cp\u003eDC+ (DCEP) preferred; AC acceptable\u003c\/p\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth colspan=\"1\" rowspan=\"1\"\u003e\u003cp\u003eWelding positions\u003c\/p\u003e\u003c\/th\u003e\n\u003ctd colspan=\"1\" rowspan=\"1\"\u003e\u003cp\u003eAll positions: 1G, 2G, 3G, 4G\u003c\/p\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth colspan=\"1\" rowspan=\"1\"\u003e\u003cp\u003eMin tensile strength\u003c\/p\u003e\u003c\/th\u003e\n\u003ctd colspan=\"1\" rowspan=\"1\"\u003e\u003cp\u003e70,000 psi (483 MPa)\u003c\/p\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth colspan=\"1\" rowspan=\"1\"\u003e\u003cp\u003eMin yield strength\u003c\/p\u003e\u003c\/th\u003e\n\u003ctd colspan=\"1\" rowspan=\"1\"\u003e\u003cp\u003e58,000 psi (400 MPa)\u003c\/p\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth colspan=\"1\" rowspan=\"1\"\u003e\u003cp\u003eElongation\u003c\/p\u003e\u003c\/th\u003e\n\u003ctd colspan=\"1\" rowspan=\"1\"\u003e\u003cp\u003e22% minimum\u003c\/p\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth colspan=\"1\" rowspan=\"1\"\u003e\u003cp\u003eMax diffusible hydrogen\u003c\/p\u003e\u003c\/th\u003e\n\u003ctd colspan=\"1\" rowspan=\"1\"\u003e\u003cp\u003e≤4 mL\/100g (H4 designation)\u003c\/p\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth colspan=\"1\" rowspan=\"1\"\u003e\u003cp\u003eMoisture resistance\u003c\/p\u003e\u003c\/th\u003e\n\u003ctd colspan=\"1\" rowspan=\"1\"\u003e\u003cp\u003eR designation + XMR enhanced moisture resistance\u003c\/p\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth colspan=\"1\" rowspan=\"1\"\u003e\u003cp\u003eTypical current range\u003c\/p\u003e\u003c\/th\u003e\n\u003ctd colspan=\"1\" rowspan=\"1\"\u003e\u003cp\u003e3\/32 in: 55–90 A\u003c\/p\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth colspan=\"1\" rowspan=\"1\"\u003e\u003cp\u003eManufacturer\u003c\/p\u003e\u003c\/th\u003e\n\u003ctd colspan=\"1\" rowspan=\"1\"\u003e\u003cp\u003eLincoln Electric\u003c\/p\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth colspan=\"1\" rowspan=\"1\"\u003e\u003cp\u003eStandards compliance\u003c\/p\u003e\u003c\/th\u003e\n\u003ctd colspan=\"1\" rowspan=\"1\"\u003e\u003cp\u003eAWS A5.1\/A5.1M E7018 H4R\u003c\/p\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\u003ch2\u003eBest Applications for Lincoln Excalibur 7018 XMR 3\/32 in\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\u003cp\u003e\u003cstrong\u003eRoot pass welding on structural steel:\u003c\/strong\u003e The 3\/32 in diameter provides precise control in tight root openings and restricted-access joints where 1\/8 in is too large.

XMR allows extended out-of-oven time in humid or challenging field environments while maintaining ≤4 mL\/100g diffusible hydrogen for code structural applications.\u003c\/p\u003e\u003cp\u003eWhat is the difference between E7018 XMR and E7018 MR?\u003c\/p\u003e\u003cp\u003eBoth XMR and MR provide moisture-resistant coatings that allow extended out-of-oven time compared to standard E7018. XMR (Extra Moisture Resistant) provides a higher level of moisture resistance and longer maximum out-of-oven exposure than standard MR. For applications in very humid, rainy, or exposed field conditions, XMR is the better choice to maintain H4 hydrogen performance over extended exposure periods.\u003c\/p\u003e\u003cp\u003eWhat amperage for 3\/32 inch 7018 electrodes?\u003c\/p\u003e\u003cp\u003eFor 3\/32 in (2.4 mm) E7018 XMR, the typical amperage range is 55–90 A. Use 55–65 A for overhead and vertical, 65–75 A for general all-position work, and 80–90 A for flat and horizontal on heavier sections. Compared to 1\/8 in E7018 (90–150 A range), the 3\/32 in diameter requires significantly lower amperage — incorrect (too high) amperage will cause excessive penetration and burn-through on thin material.\u003c\/p\u003e\u003cp\u003eIs 3\/32 E7018 good for root passes?\u003c\/p\u003e\u003cp\u003eYes — 3\/32 in E7018 is commonly used for root passes in structural CJP groove welds where the root opening is too tight for 1\/8 in diameter. The smaller diameter fits into the root gap and provides precise control of keyhole formation and root face fusion. The XMR moisture-resistant coating ensures that the root pass achieves H4 hydrogen performance even after extended time out of the holding oven on field applications.\u003c\/p\u003e\u003cp\u003eCan Lincoln 7018 XMR be used without an oven on job sites?\u003c\/p\u003e\u003cp\u003eThe XMR coating provides significantly extended out-of-oven exposure compared to standard E7018 — making it more practical for field job sites where electrode ovens are inconvenient. However, for code-critical structural work (AWS D1.1, ASME), even XMR electrodes must be stored per the applicable code requirements.
