ED511232 - Lincoln 7018AC 4.0mm Low Hydrogen Stick Electrode

Smooth 7018 Welding on Your AC Machine

If you have ever tried to run a standard 7018 rod on an AC "buzz box" welder, you know the frustration: the rod sticks, the arc stutters, and it keeps popping out. Lincoln Electric solves this problem with the 7018AC 4.0mm Stick Electrode. This rod is specifically engineered to run like a dream on AC power sources, giving you the professional, heavy-duty strength of a low-hydrogen weld without the headache of fighting your arc.

Why Choose Lincoln 7018AC?
This electrode is perfect for structural projects, heavy equipment repairs, and general fabrication where weld strength is critical. The "AC" designation means the flux coating contains special stabilizers that keep the arc lit even as the current alternates. The result is a smooth, creamy puddle that wets out nicely at the toes, minimizing undercut and making you look like a pro. The 4.0mm size is excellent for thicker materials, allowing you to lay down significant metal in fewer passes.

User-Friendly Performance
Beyond just staying lit, the Lincoln 7018AC offers easy restriking, which is a huge time-saver when you are tacking up a project or moving between joints. The slag is friable and easy to remove, often peeling up in large sections, which reduces cleanup time with your chipping hammer. Whether you are welding in the flat, horizontal, vertical, or overhead position, this rod gives you control over the puddle. It is the ideal choice for welders who need the reliability of a 7018 structural weld but rely on AC transformers for their power.
