CS87503 - 0.039 Inch Plasma Drag Tip for Air/Nitrogen

Technical Overview of the CS87503 Plasma Tip

The CS87503 is a precision-engineered plasma cutting tip designed to facilitate high-quality thermal cutting processes. This consumable component features a calibrated orifice diameter of 0.039 inches, a critical dimension that governs the constriction of the plasma arc and the density of the energy stream. By maintaining a tight tolerance on the orifice size, this tip ensures a stable and focused arc column, which is essential for achieving clean kerf lines and minimizing dross accumulation on the workpiece.

One of the defining technical characteristics of this model is its dual-gas compatibility. It is rated for use with both compressed Air and Nitrogen (N2). The ability to utilize Nitrogen makes this tip particularly suitable for applications involving non-ferrous metals like stainless steel and aluminum, where oxidation control is a priority. Conversely, its compatibility with standard shop air allows for economical operation during general carbon steel fabrication. The designation "DR" indicates that this tip is optimized for drag cutting techniques, where the torch can be moved directly along the surface of the material without the need for a standoff distance, simplifying the operation for manual cutting tasks.

Thermal management is handled through the component's high-grade copper construction, which efficiently dissipates the intense heat generated during the plasma phase transition. Proper heat dissipation is vital to prevent premature erosion of the orifice bore, known as keyholing, which degrades cut quality. This tip serves as the final constriction point for the gas flow before it exits the torch, playing a pivotal role in the ionization process and the velocity of the plasma jet.

Operators should monitor the condition of the 0.039" orifice regularly. As the electrode emits electrons and the gas ionizes, the high-velocity plasma stream inevitably wears the copper bore. Replacing the tip when the orifice becomes out-of-round is necessary to maintain the specified cutting parameters and voltage characteristics of the power source.
