E7018 H4R is an AWS A5.1 low-hydrogen iron-powder basic-coated SMAW electrode with 70 ksi minimum tensile, plus the H4 diffusible-hydrogen designator (≤4 mL/100g deposited weld metal) and the R designator for low-moisture-pickup coating. H4R coatings resist atmospheric moisture pickup, reducing the risk of hydrogen-induced cracking on high-restraint and high-strength weldments. Runs DC+ or AC in all positions; preferred for code-quality structural, pressure-vessel, and shipbuilding work where strict hydrogen control is required.
Is this the same electrode as the parent Lincoln Jet-LH MR RSP grade, just in a different package?
Yes. SKU ED033519 is the same AWS A5.1/A5.1M E7018 H4R classification as every other size in the Lincoln Jet-LH MR RSP family. The only difference is diameter (5/32 in) and package format (4 x 5 lb easy-open cans). Polarity, position, and tensile properties are identical to the parent grade.
How many rods are in this 4 x 5 lb easy-open cans?
Approximately ~17 per 5 lb container (~68 total). Exact count varies with manufacturing tolerance but a 4 x 5 lb easy-open cans of 5/32 in Lincoln Jet-LH MR RSP 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?
5/32 in is well-suited for flat and horizontal fill on heavier plate and structural welds. 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 Jet-LH MR RSP share identical mechanical properties (AWS A5.1/A5.1M E7018 H4R) 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 (120-220 A). Most general-purpose stinger holders (e.g. 300-500 A class) handle 5/32 in Lincoln Jet-LH MR RSP 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 Jet-LH MR RSP may be available in a Buy America compliant version - see the parent grade page for all available compliance variants.
