5500323000 - ESAB OK 55.00 E7018-1 3.2mm Welding Rods

Performance and Usability for the Professional Welder

When you are out in the field or in the shop working on critical joints, you need a rod that runs smooth and passes X-ray every time. The ESAB OK 55.00 (E7018-1) is that rod. Known for its exceptional arc stability and puddle control, this 3.2mm stick electrode takes the frustration out of welding high-strength steel. Whether you are welding structural beams, repairing heavy machinery, or working on ship hulls, the OK 55.00 gives you the confidence that your welds will hold up against stress and cold temperatures.

One of the standout features of this electrode is its forgiveness. It strikes easily and maintains a consistent arc, reducing the chance of porosity and inclusions. The slag coverage is complete but detaches easily after cooling, saving you time on cleanup and grinding between passes. Because it is an E7018-1 class rod, it offers better impact toughness than standard 7018s, which is a huge plus if you are working on projects that require specific code compliance for low-temperature service.

This rod runs great on both AC and DC+, giving you flexibility depending on your machine setup. The 3.2mm (1/8") size is the perfect middle ground for general fabrication—heavy enough to lay down metal quickly in flat positions, but manageable enough for out-of-position work when you need it. If you are looking for a reliable "low-hy" rod that resists cracking and produces professional-looking beads, the ESAB OK 55.00 is a solid choice for your arsenal.
