20-1221 - Thermal Dynamics 70A Tip 0.047" for PCH-120/Maximizer 300 (10-Pack)

Precision Plasma Cutting with Thermal Dynamics 20-1221

The Thermal Dynamics 20-1221 Tip is a critical consumable component designed for high-performance plasma cutting operations. Engineered specifically for use with the PCH-120 and Maximizer™ 300 plasma torches, this tip features a precise 0.047-inch orifice that constricts the plasma arc to generate the high-velocity stream necessary for cutting metal. Rated for 70 Amps, this nozzle is optimized to deliver clean, dross-free cuts on a variety of conductive metals, including mild steel, stainless steel, and aluminum.

Manufacturing tolerances are paramount in plasma consumables, and Thermal Dynamics ensures that every 20-1221 tip meets strict quality standards. The concentricity of the orifice is essential for maintaining a straight cut angle; a worn or poorly manufactured tip can lead to beveled edges and poor cut quality. By using genuine OEM parts, operators ensure that the gas flow and electrical arc are perfectly aligned, maximizing the efficiency of the plasma system.

This tip is constructed from high-quality copper alloy, chosen for its superior thermal conductivity. Efficient heat dissipation is vital during 70A operation to prevent the tip from overheating, which can cause the orifice to deform or melt. The design allows for effective cooling gas flow around the nozzle, extending the service life of the consumable and reducing downtime for changeovers. Whether you are performing fabrication work, industrial maintenance, or HVAC cutting, the 20-1221 tip provides the reliability needed for consistent production.

Regular inspection of the tip is recommended. If the orifice becomes out-of-round or enlarged, cut quality will deteriorate, and the tip should be replaced immediately. This product is typically supplied in packs, ensuring you have replacements on hand to maintain continuous operation.
