Lincoln 7018-AC RSP is an AWS A5.1 E7018 H8 low-hydrogen iron-powder basic-coated SMAW electrode in Lincoln's Ready Strike Pack hermetically sealed 1 lb resealable can format, engineered to run on AC welding machines including low open-circuit-voltage buzzboxes. The RSP packaging keeps moisture pickup near factory-fresh between jobs, eliminating the need for a rod oven for short-run AC E7018 work. 70 ksi minimum tensile, all-position, AC or DC+.
Is this the same electrode as the parent Lincoln 7018-AC RSP grade, just in a different package?
Yes. SKU ED033515 is the same AWS A5.1/A5.1M E7018 classification as every other size in the Lincoln 7018-AC RSP family. The only difference is diameter (1/8 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 ~26 per 5 lb container (~106 total). Exact count varies with manufacturing tolerance but a 4 x 5 lb easy-open cans of 1/8 in Lincoln 7018-AC 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, 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?
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 7018-AC RSP 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 to restore full code performance.
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 7018-AC 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 7018-AC RSP may be available in a Buy America compliant version - see the parent grade page for all available compliance variants.
