21-1095 - Thermal Dynamics 200A SS/AL Plasma Tip (5-Pack)

Precision Engineering for High-Amperage Non-Ferrous Cutting

The Thermal Dynamics 21-1095 Tip is a critical component for industrial plasma cutting systems, specifically designed to handle the rigorous demands of 200-amp operations on non-ferrous materials. In high-definition and standard plasma cutting, the tip (or nozzle) serves the vital function of constricting the plasma arc and focusing the gas flow. At 200 amps, the energy density is immense, requiring a consumable that can withstand extreme thermal loads while maintaining geometric integrity. This specific tip is engineered for Stainless Steel and Aluminum applications, where the fluid dynamics of the molten pool differ significantly from mild steel.

When cutting stainless steel or aluminum, particularly at high amperages, the choice of consumable directly impacts the edge quality, angularity, and dross formation. The 21-1095 features a precision-machined orifice sized perfectly for 200A flow rates, ensuring that the plasma gas—often a mix involving Nitrogen, Hydrogen (H35), or Argon depending on the specific process setup—is accelerated correctly to eject molten material efficiently. The copper alloy construction provides superior thermal conductivity, rapidly dissipating heat away from the orifice edge to prevent premature erosion or "keyholing," which degrades cut quality.

This product is marked "MRKD-STD," indicating it meets the standard marking and manufacturing tolerances of Thermal Dynamics' OEM specifications. For operators of Ultra-Cut systems or similar high-capacity power sources, using genuine OEM parts like the 21-1095 is essential for maintaining the system's duty cycle and cut rating. Deviations in tip geometry, even by fractions of a millimeter, can lead to arc instability, double-arcing, or damage to the electrode and torch head. By utilizing the 21-1095 for its intended SS/AL application, users ensure optimal arc characteristics that reduce secondary processing requirements such as grinding or machining.

Supplied in a package of five, these tips allow for consistent production runs. In automated or mechanized environments, predictable consumable life is key to calculating operational costs. The 21-1095 delivers that predictability, offering a stable wear rate that aligns with the replacement cycles of the accompanying electrodes. Whether utilized in underwater cutting or dry table applications, this tip represents the intersection of metallurgical science and fluid dynamics required for heavy industrial fabrication.
