Lincoln Excalibur 7018 MR is an AWS A5.1 E7018 H4R low-hydrogen iron-powder basic-coated moisture-resistant SMAW electrode. 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. Runs DC+ or AC in all positions with 70 ksi minimum tensile, and is Lincoln's premium pick for structural steel, pressure vessel, pipe, and shipbuilding where moisture-control discipline matters.
Is this the same electrode as the parent Lincoln Excalibur 7018 XMR grade, just in a different package?
Yes. SKU ED037425 is the same AWS A5.1/A5.1M E7018 classification as every other size in the Lincoln Excalibur 7018 XMR family. The only difference is diameter (3/32 in) and package format (3 x 10 lb easy-open cans). Polarity, position, and tensile properties are identical to the parent grade.
How many rods are in this 3 x 10 lb easy-open cans?
Approximately ~94 per 10 lb container (~282 total). Exact count varies with manufacturing tolerance but a 3 x 10 lb easy-open cans of 3/32 in Lincoln Excalibur 7018 XMR typically contains in this range.
What is the shelf life if I do not use them all?
Sealed cans have an indefinite shelf life when stored unopened in a dry environment. Once opened, the H4R moisture-resistant coating tolerates brief atmospheric exposure better than standard low-hydrogen rods, but for code-quality work rods should be stored in a heated rod oven at 250-300 F and rebaked at 500-800 F if exposed beyond 4 hours.
What diameter should I use for common applications?
3/32 in is well-suited for root passes, thin material, and out-of-position work. Heavier base metal and higher deposition typically calls for one diameter up; thinner sheet and root passes go one diameter down. See the parent grade page for full diameter-to-amperage guidance.
Can I mix this size with other diameters on the same job?
Yes, provided your procedure qualification (WPS) covers the diameter range. Many shops use one diameter for root, one for fill, and one for cap. All sizes within Lincoln Excalibur 7018 XMR share identical mechanical properties (AWS A5.1/A5.1M E7018) so weld metal chemistry is consistent across passes.
Do I need to rebake these after the can is opened?
Yes 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. The H4R designation provides extra moisture-pickup margin but rebaking is still required for code work after extended exposure.
Does this size require a special holder or stinger?
Use 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 Lincoln Excalibur 7018 XMR without issue. For sustained high-amperage runs on larger diameters, a 500 A or higher holder is recommended.
Is this Buy America compliant?
This specific SKU is not the Buy America variant. Lincoln Excalibur 7018 XMR may be available in a Buy America compliant version - see the parent grade page for all available compliance variants.
