21-1055 - Thermal Dynamics 200A Mild Steel Oxygen Plasma Tip (5-Pack)

Precision Engineering for High-Amperage Plasma Cutting

The Thermal Dynamics 21-1055 Tip is a specialized consumable component engineered for heavy-industrial plasma cutting systems operating at 200 Amperes. Designed explicitly for the processing of Mild Steel using Oxygen as the plasma gas, this tip represents the critical interface between the high-energy plasma arc and the workpiece. In high-amperage plasma cutting, the tip (or nozzle) plays a pivotal role in constricting the arc to increase energy density and velocity. The 21-1055 features a precision-machined orifice geometry that maintains arc stability and focus, which is essential for achieving square cut edges and minimizing the heat-affected zone (HAZ) on thick mild steel plates.

Thermal Dynamics utilizes advanced manufacturing techniques to ensure that every 21-1055 tip meets tight tolerance specifications. The concentricity of the orifice relative to the electrode is paramount; any deviation can lead to a skewed arc, excessive bevel, or premature failure of the consumable stack. By using genuine OEM parts, operators ensure that the gas flow dynamics within the torch head function exactly as the system designers intended. This specific tip is optimized for the exothermic reaction that occurs when Oxygen is used as the cutting gas on carbon steel, allowing for faster travel speeds and dross-free cuts compared to standard air or nitrogen processes.

Durability is a key factor in the design of the 21-1055. At 200 Amps, the thermal load on the tip is significant. Thermal Dynamics employs high-grade copper alloys and efficient heat transfer designs to manage this thermal stress, prolonging the service life of the tip even under high duty cycles. This product is supplied in a package of five, reflecting the consumable nature of the component in high-volume production environments. Regular inspection and replacement of the tip are critical maintenance protocols; a worn orifice can lead to poor cut quality, increased voltage requirements, and potential damage to the torch body. For automated or manual systems requiring 200A output on mild steel, the 21-1055 provides the reliability and precision necessary for industrial fabrication standards.
