ED038110 - Lincoln 7018 AC Stick Electrode 1/8" (10lb Carton)

Lincoln 7018 AC Stick Electrode: Superior Stability on AC Power

The Lincoln Electric 7018 AC Stick Electrode (ED038110) is a premium mild steel, low hydrogen electrode specifically formulated to provide exceptional performance when welding with Alternating Current (AC). While standard 7018 electrodes often require DC+ polarity for optimal stability, this specialized "AC" variant features a unique coating design that maintains a smooth, consistent arc even on power sources with low open circuit voltage (OCV). This makes it an indispensable consumable for workshops and field sites relying on AC buzz boxes or older welding machines.

Measuring 1/8 inch (3.2 mm) in diameter and 14 inches in length, this electrode is classified as E7018 H8, indicating its high-quality low hydrogen properties which are essential for preventing cold cracking in structural steel applications. The electrode excels in general fabrication, maintenance, and repair work where steel quality may vary. Operators will appreciate the minimal spatter levels, which significantly reduce post-weld grinding and cleanup time. Furthermore, the slag system is designed to be easily removable, revealing a clean, high-quality weld bead underneath.

One of the standout features of the Lincoln 7018 AC is its cold re-strike capability. Standard low hydrogen rods can be difficult to relight once the tip has cooled, often forming a non-conductive coating over the core wire. This electrode minimizes that issue, making it excellent for tack welding, skip welding, and applications requiring frequent stops and starts. Whether you are welding in the flat, horizontal, vertical, or overhead positions, the Lincoln 7018 AC delivers reliable penetration and mechanical properties.

Key Features
