5500604V0 - Esab OK 55.00 6.0mm E7018-1 Low Hydrogen Stick Electrodes VacPac

The Welder's Choice for Critical Structural Welds

When your project demands the absolute best in crack resistance and weld quality, the Esab OK 55.00 E7018-1 is the rod you reach for. This 6.0mm version is a beast, designed for filling large joints in thick steel plates efficiently and effectively. Known among professional welders for its smooth runnability and easy slag release, the OK 55.00 takes the frustration out of heavy stick welding. Whether you are repairing heavy machinery, working on structural steel beams, or welding pressure vessels, this electrode delivers a bead that looks as good as it performs.

The magic of the OK 55.00 lies in its advanced LMA (Low Moisture Absorption) coating. This formulation ensures that the weld metal remains extremely low in diffusible hydrogen, which is the primary culprit behind delayed cracking in thick steels. Furthermore, Esab protects this coating with their VacPac system. Forget about hauling around a portable rod oven or worrying if your rods have absorbed moisture from the shop air. As long as the vacuum seal is tight, these rods are factory-fresh and ready to burn the moment you need them.

At 6.0mm (approx. 1/4 inch) diameter and 18 inches in length, these rods are designed for high-amperage welding, typically in the 200-350A range. They excel in the flat and horizontal positions, producing a fluid puddle that wets out nicely at the toes. The arc is forgiving yet forceful, providing the penetration needed for root and hot passes on heavy prep work (though 6mm is usually for fill/cap). The resulting weld metal offers exceptional toughness, even in sub-zero temperatures, making it ideal for Canadian winters and arctic service applications.

Why Welders Prefer OK 55.00:

• Ready to Weld: Grab a VacPac and go—no baking, no waiting.
• Superior Control: Excellent arc stability on both AC and DC+.
• Toughness: Charpy V-Notch tested for high impact strength at -45°C.
