21-1152 - Thermal Dynamics 70A XTL Plasma Tip for Mild Steel (10-Pack)

Precision Cutting with Thermal Dynamics 70A XTL Tips

For professional welders and fabricators utilizing Thermal Dynamics plasma systems, the 21-1152 XTL Tip is an essential component for 70 Amp cutting processes. This nozzle tip is specifically calibrated for mild steel applications, ensuring that your cuts are clean, precise, and professional. The "XTL" designation stands for Extended Life, highlighting the advanced manufacturing techniques used to create a consumable that resists wear and erosion longer than standard tips. This durability is particularly beneficial in high-volume production environments where maximizing arc-on time is a priority.

The 21-1152 operates effectively with both Oxygen and Air plasma gases. This flexibility allows fabricators to adapt to available gas supplies while still achieving excellent metallurgical results on mild steel. The tip's design facilitates a constricted, high-density plasma arc that melts through the workpiece efficiently, blowing away molten metal to leave a smooth edge. Proper tip selection is vital; using a 70A tip for 70A settings ensures the orifice is not blown out (which happens if amperage is too high for the tip) or the arc doesn't sputter (if amperage is too low). This specific match guarantees the best possible cut quality and consumable longevity.

Welders Supply offers these tips in packs of 10, providing a cost-effective solution for shop inventory management. Keeping a healthy stock of 21-1152 tips means you are always prepared for long cutting shifts. Regular inspection and replacement of the plasma tip are necessary maintenance steps; a worn orifice can lead to beveled cuts, excessive dross, and unstable arcs. By replacing your consumables with genuine Thermal Dynamics parts, you restore your torch's performance to factory standards.

These tips are designed to work in harmony with the electrode, swirl ring, and shield cap of your torch assembly. The precise machining ensures proper alignment and gas distribution, which cools the consumable stack and shapes the arc. Whether you are performing straight cuts, gouging, or intricate shape cutting on mild steel, the Thermal Dynamics 21-1152 delivers the consistency required for high-quality fabrication. Invest in genuine consumables to protect your equipment and ensure the safety and quality of your work.
