770791 - Hobart Plasma Electrodes for XT Series Torches (2-Pack)

High-Performance Plasma Electrodes for Hobart AirForce Cutters

The Hobart 770791 Plasma Electrodes are essential consumables designed specifically for the XTR series of plasma torches. Engineered to meet the rigorous demands of plasma cutting, these electrodes serve as the primary contact point for the electrical arc, playing a critical role in the ionization of gas and the generation of the plasma stream. This package contains two genuine Hobart electrodes, ensuring that operators have immediate replacements on hand to maintain workflow efficiency and minimize downtime during critical fabrication tasks. By utilizing OEM parts, users ensure that the electrical resistance and thermal properties match the specific design requirements of their power source.

Compatibility is a key factor when selecting plasma consumables. These electrodes are manufactured to precise tolerances for a perfect fit with Hobart XT12R, XT30R, and XT40R plasma torches. These torches are standard equipment on the popular Hobart AirForce 12ci, AirForce 27i, and AirForce 40i plasma cutting machines. Using genuine OEM parts guarantees that the cooling gas flows correctly around the consumable stack, preventing overheating and extending the lifespan of both the torch head and the consumables themselves. Unlike aftermarket alternatives, Hobart electrodes are built to strictly adhere to the manufacturer's specifications for arc starting and stability, which is vital for automated or manual cutting processes.

The electrode is one of the most frequently replaced components in a plasma torch. Over time, the hafnium insert within the copper body of the electrode erodes due to the intense heat of the plasma arc. Regular inspection of the electrode is vital; if the pit depth of the insert becomes excessive, the arc can become unstable, leading to poor cut quality, excessive dross, or even damage to the torch tip and retaining cap. By replacing worn electrodes promptly with these high-quality Hobart 770791 units, users can ensure clean, precise cuts on mild steel, stainless steel, and aluminum. It is generally recommended to inspect the electrode every time the nozzle is changed to ensure the entire consumable stack is in optimal condition.

Each pack includes two electrodes, providing a cost-effective solution for routine maintenance. Whether you are operating a small fabrication shop, performing automotive repairs, or managing facility maintenance, keeping a supply of these electrodes ensures your AirForce plasma cutter is always ready for operation. Trust in the quality and reliability of Hobart Welding Products to deliver consistent performance and superior results in all your metal cutting applications. These components are manufactured in Czechia to high industrial standards, ensuring reliability you can count on for every cut.
