21-1050 - Thermal Dynamics 30A Plasma Tip 10-Pack

Precision Engineering for Plasma Systems

The Thermal Dynamics 21-1050 Tip is a critical consumable component designed for specific low-amperage plasma cutting applications. Engineered to operate at 30 Amperes, this tip features a precision-machined orifice that constricts the plasma arc to generate the high-velocity, high-temperature plasma stream required for cutting conductive metals. The geometry of the tip is strictly controlled during manufacturing to ensure the gas flow dynamics are optimized for arc stability and cut quality. This specific tip is compatible with a range of legacy and standard Thermal Dynamics torches, including the PCH/M-25, PCH/M-38, and related series found on Pak Master systems.

In plasma cutting, the tip (or nozzle) serves to focus the plasma arc. As the electrode generates the arc, the tip constricts it, increasing the energy density. The 21-1050 is designed for 30A operation, which is ideal for cutting thinner gauge materials where precision and minimal heat-affected zones (HAZ) are prioritized over raw severance thickness. Using a tip rated for the correct amperage is vital; using a 30A tip at higher amperages will rapidly widen the orifice and destroy the tip, while using it at significantly lower amperages may result in an unstable arc. These tips are manufactured from high-quality copper alloys to withstand the intense thermal loads inherent in the plasma process, though they are considered consumables and will wear over time due to erosion from the plasma arc and molten metal blowback.

This product is supplied as a package of 10, facilitating inventory management for industrial environments. Regular inspection of the tip orifice is recommended. A perfectly round orifice produces a straight, clean cut, whereas an oval or obstructed orifice will lead to beveled cuts and excessive dross. The 21-1050 ensures that operators can maintain the factory-specified performance of their Thermal Dynamics plasma cutting systems by replacing worn components with genuine OEM parts.
