OVERVIEW

Performance and Usability for the Professional Welder

When your project demands more strength than a standard 7018 rod can provide, the Hobart Hoballoy 9018-M is your go-to solution. Designed for the professional welder tackling high-strength low-alloy (HSLA) steels, this 1/8-inch stick electrode delivers a robust 90,000 psi tensile strength without sacrificing weldability. If you are familiar with running 7018, you will appreciate the smooth, consistent arc of the Hoballoy 9018-M. It runs beautifully in all positions—flat, horizontal, vertical, and overhead—giving you the versatility needed for complex structural repairs or fabrication jobs where positioning the workpiece isn't an option.

One of the standout features of this rod is its puddle control. The iron powder coating helps the puddle wet out smoothly at the toes, reducing the risk of undercut and creating a professional bead profile with minimal effort. The slag coverage is complete but friable, meaning it cools to a crust that often lifts off by itself or with a light tap of your chipping hammer. This is a huge time-saver when you are running multiple passes on thick plate and need to ensure clean inter-pass fusion.

The 10 lb can is the perfect size for specific jobs where a full 50 lb tin would go to waste. Because this is a low-hydrogen rod, moisture is the enemy. The hermetically sealed can ensures that when you crack it open, the rods are factory-fresh and ready to perform. Whether you are welding on heavy equipment frames, pressure vessels, or military-grade structures, the Hoballoy 9018-M gives you the confidence that your welds will hold up under stress and low temperatures.

Dial in your machine between 110 and 150 amps (depending on your specific power source and position), and you will find this rod forgiving yet powerful. It bites in for good penetration but maintains a stable arc that doesn't wander. For vertical-up welding, the shelf is easy to build, allowing you to stack dimes even on high-strength steel. Upgrade your stick welding arsenal with Hobart's trusted reliability.

FAQ

This electrode is classified as E9018-M under AWS A5.5 specifications.

The recommended amperage range is typically between 110 and 150 amps.

Yes, as a low-hydrogen electrode, once the hermetically sealed can is opened, the rods should be stored in an oven (usually 250°F-300°F) to prevent moisture absorption.

The weld deposit has a minimum tensile strength of 90,000 psi.

Yes, you can, but it is considered 'over-matching.' It is generally better to match the rod strength to the base metal (e.g., 7018 for mild steel) to prevent stress concentrations, but it will weld fine.

You can run this electrode on DCEP (Direct Current Electrode Positive) or AC (Alternating Current). DCEP is preferred for smoother operation.

Yes, the E9018-M is an all-position rod. The '1' in the classification indicates it can be used in flat, horizontal, vertical, and overhead positions.

It runs very similarly to a 7018 but produces a weld with significantly higher tensile strength (90ksi vs 70ksi). It is used when the base metal requires that extra strength.
