21-1309 - Thermal Dynamics 400A Oxygen Plasma Tip for Mild Steel

Genuine Thermal Dynamics 21-1309 Tip for 400A Mild Steel Cutting

When your shop is running high-volume production on thick mild steel, you need consumables that can take the heat. The Thermal Dynamics 21-1309 Tip is built for exactly that—delivering 400 Amps of cutting power to slice through heavy plate with speed and precision. This tip is designed for use with Oxygen (O2) plasma gas, which is the industry standard for getting clean, metallic finishes on mild steel. If you are running an Ultra-Cut system or similar high-amperage automated setup, this is the genuine replacement part you need to keep your cuts square and your downtime low.

Why choose the 21-1309? It comes down to cut quality and life. At 400 amps, a generic or worn tip can cause the arc to wander, leading to beveled edges and excessive dross that slows down your welders and finishers. This genuine Thermal Dynamics tip maintains a tight, focused arc that blows through steel cleanly. The use of oxygen gas helps burn through the metal faster than air or nitrogen, giving you faster travel speeds and a cleaner edge that is ready for welding immediately. It’s a critical component for any fabricator working with structural steel or heavy equipment manufacturing.

Don't risk your torch head or your project deadlines with inferior parts. The 21-1309 is manufactured to exact specifications to ensure it seats perfectly in your torch, providing optimal electrical contact and cooling. Keep your automated table running smoothly and your cut quality high with this essential consumable.
