E7028 H8 is an AWS A5.1 high-iron-powder low-hydrogen SMAW electrode with 70 ksi minimum tensile and an H8 diffusible-hydrogen designator (≤8 mL/100g). The thick iron-powder coating delivers up to 30% higher deposition rate than standard E7018 for production fabrication. Limited to flat and horizontal fillet positions; requires the same controlled low-hydrogen storage and rebake discipline as E7018 for code work.
Is this the same electrode as the parent Lincoln Excalibur 7028 grade, just in a different package?
Yes. SKU ED032636 is the same AWS A5.1/A5.1M E7028 H8 classification as every other size in the Lincoln Excalibur 7028 family. The only difference is diameter (5/32 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 ~170 rods. Exact count varies with manufacturing tolerance but a 50 lb easy-open can of 5/32 in Lincoln Excalibur 7028 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, low-hydrogen rods exposed beyond 4 hours of atmospheric humidity should be rebaked at 500-800 F for 1-2 hours or stored in a heated rod oven at 250-300 F to restore full code performance.
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 Excalibur 7028 share identical mechanical properties (AWS A5.1/A5.1M E7028 H8) 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 to restore full code performance.
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 Excalibur 7028 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 7028 may be available in a Buy America compliant version - see the parent grade page for all available compliance variants.
