770496 - Hobart AirForce 250ci and 500i Plasma Tip and Electrode Replacement Kit

Technical Precision for AirForce Plasma Systems

The Hobart 770496 Tip and Electrode Kit is engineered to meet the rigorous demands of the AirForce 250ci and AirForce 500i plasma cutting systems. This kit specifically supports the HP-25 and HP-50 torch assemblies, providing the critical wear components necessary for the plasma generation process. In a plasma torch, the electrode acts as the emitter of the electric arc, while the tip (or nozzle) constricts the gas flow to focus that energy into a high-density cutting stream. Because these two components are subjected to the highest thermal loads in the system, they are the most frequently replaced parts. This kit ensures you have matched sets of these vital components, manufactured to Hobart's strict OEM specifications.

The electrodes included in this kit are constructed with a copper body and a hafnium insert. The hafnium is the emissive element that facilitates the arc; as it wears, a pit forms in the center of the electrode. Replacing the electrode before this pit becomes too deep is crucial to prevent the arc from attaching to the copper body, which can cause catastrophic failure of the torch head. Similarly, the copper tips are precision-drilled to shape the plasma arc. As the orifice wears and becomes out-of-round, cut quality deteriorates, leading to beveled edges and excessive dross. By replacing both the tip and electrode simultaneously using this kit, operators can maintain the optimal electrical and fluid dynamic properties of the torch.

This consumable kit is ideal for professional welders and fabricators who rely on the portability and utility of the AirForce series. The kit format simplifies inventory management, ensuring that a fresh set of consumables is always available when cut quality begins to degrade. Proper maintenance of the torch front-end not only improves the quality of the work but also extends the duty cycle and lifespan of the plasma cutter itself by reducing unnecessary electrical resistance and heat buildup. Trust in genuine Hobart engineering to keep your AirForce 250ci or 500i operating at peak efficiency.
