249928 - Miller XT40 40A Plasma Cutting Tips (3-Pack)

Miller 249928 40 Amp Plasma Tip (3-Pack)

The Miller 249928 40 Amp Tip is a critical consumable component designed exclusively for the XT40 and XT40M plasma torches, which are standard equipment on the Miller Spectrum 625 X-TREME plasma cutter. These tips are engineered to constrict the plasma arc, focusing the energy density to achieve precise, clean cuts on conductive metals such as mild steel, stainless steel, and aluminum. Manufactured to Miller's exacting tolerances, these genuine replacement tips ensure that your plasma cutting system operates at peak efficiency and maintains the manufacturer's specified duty cycle.

The tip features a calibrated orifice that shapes the plasma stream; over time, this orifice wears and widens due to the intense heat and velocity of the ionized gas. A worn tip can lead to a wider kerf, reduced cutting speed, unstable arcs, and increased dross accumulation on the workpiece. Replacing the tip regularly is essential for maintaining cut quality and protecting the torch head from damage caused by arc blowback or overheating. This package contains three (3) 40-amp tips, providing operators with necessary spares to minimize downtime during critical production runs or maintenance tasks.

The XT40 torch design utilizes advanced airflow dynamics in conjunction with these tips to cool the consumable stack and prolong life. The copper construction of the tip ensures excellent thermal conductivity, rapidly dissipating the heat generated during the plasma process. It is important to note that these tips are specifically keyed for the XT series torches and are not compatible with older Miller ICE-series torches. Using genuine Miller consumables guarantees proper fitment and gas flow dynamics, which are crucial for the arc control technologies employed by Miller machines. When installed, the tip sits between the electrode and the retaining cup, acting as the primary nozzle for the plasma arc.

For industrial MRO applications, maintaining a stock of 249928 tips is highly recommended. Signs of wear include an out-of-round orifice or significant cratering on the face of the tip. Continued use of a worn tip can lead to electrode failure and potential damage to the swirl ring and torch body. By using OEM parts, users ensure compliance with the performance specifications of the Spectrum 625 X-TREME.
