Lincoln Excalibur 7018-1 MR is an AWS A5.1 E7018-1 H4R low-hydrogen iron-powder basic-coated moisture-resistant SMAW electrode with the -1 suffix designating improved low-temperature impact toughness (20 ft-lb at -50 F minimum). The H4R designation delivers up to 60% less moisture pickup than standard E7018-1 electrodes, making it Lincoln's premium pick for code-quality structural, offshore, and arctic fabrication where both impact toughness and moisture control matter. Runs DC+ or AC in all positions with 70 ksi minimum tensile.
Is this the same electrode as the parent Lincoln Excalibur 7018-1 MR grade, just in a different package?
Yes. SKU ED028702 is the same AWS A5.1/A5.1M E7018-1 classification as every other size in the Lincoln Excalibur 7018-1 MR family. The only difference is diameter (1/8 in) and package format (50 lb easy-open can). Polarity, position, and tensile properties are identical to the parent grade.
How many rods are in this 50 lb easy-open can?
Approximately ~265 rods. Exact count varies with manufacturing tolerance but a 50 lb easy-open can of 1/8 in Lincoln Excalibur 7018-1 MR 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?
1/8 in is well-suited for general all-position fill and cap passes on plate up to 1/2 in. 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 7018-1 MR share identical mechanical properties (AWS A5.1/A5.1M E7018-1) 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 (90-165 A). Most general-purpose stinger holders (e.g. 300-500 A class) handle 1/8 in Lincoln Excalibur 7018-1 MR 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 7018-1 MR may be available in a Buy America compliant version - see the parent grade page for all available compliance variants.
