What is the AWS classification of the Lincoln ED033516 Lincoln AK-10 Stick (SMAW) Electrode, 5/32x14 in, (4) 5 lb Tube?

The Lincoln ED033516 Lincoln AK-10 Stick (SMAW) Electrode, 5/32x14 in, (4) 5 lb Tube carries AWS E7018 H8 classification. The AWS electrode classification system encodes the electrode's minimum tensile strength (first two digits, in ksi), recommended positions (third digit), and coating/current type (fourth digit). For example, E7018 = 70 ksi tensile minimum, all-position, iron powder low-hydrogen coating, AC or DC+.

What diameter is the Lincoln ED033516 Lincoln AK-10 Stick (SMAW) Electrode, 5/32x14 in, (4) 5 lb Tube available in, and what amperage does each require?

The Lincoln ED033516 Lincoln AK-10 Stick (SMAW) Electrode, 5/32x14 in, (4) 5 lb Tube is available in 5/32 diameter. Electrode diameter selection depends on base metal thickness and joint design: 3/32 in suits 1/16–3/16 in material (40–80A), 1/8 in covers 3/16–3/8 in (80–130A), 5/32 in suits 5/16–1/2 in (110–165A), and 3/16 in+ suits heavy plate over 1/2 in. Always check the electrode manufacturer's current range recommendations for the specific AWS class.

What polarity and current type does the Lincoln ED033516 Lincoln AK-10 Stick (SMAW) Electrode, 5/32x14 in, (4) 5 lb Tube require?

E6010 and E6011 electrodes run on DC+ (direct current, electrode positive) and are designed for cellulosic coatings that generate deep penetrating, fast-freeze arcs — preferred for root passes on pipe and out-of-position work. E6013 runs on AC or DC and is a general-purpose electrode for light fabrication. E7018 is a low-hydrogen iron powder electrode that runs on AC or DC+ — it produces high-quality, low-hydrogen deposits for critical structural and code welding. Never substitute electrode types without understanding the current/polarity requirements.

How should I store low-hydrogen stick electrodes like the Lincoln ED033516 Lincoln AK-10 Stick (SMAW) Electrode, 5/32x14 in, (4) 5 lb Tube?

Low-hydrogen electrodes (E7018, E7016, E8018, etc.) must be stored in a rod oven at 250–300°F after opening to maintain low hydrogen content. Electrodes that have been exposed to moisture for more than 2–4 hours should be re-dried per AWS D1.1 recondition procedures (typically 700–800°F for 1 hour for low-hydrogen electrodes). General-purpose (non-low-hydrogen) electrodes like E6013 are less moisture-sensitive but should still be kept dry. Never use visibly damp or rusted electrodes.
