21-1308 - Thermal Dynamics 400A Mild Steel Electrode for Ultra-Cut Systems (5-Pack)

Precision High-Amperage Plasma Consumables

The Thermal Dynamics 21-1308 Electrode is a critical component designed for heavy-industrial plasma cutting applications. Engineered specifically for the Ultra-Cut (UC) series of high-precision plasma systems, this electrode is rated for 400 Amps, making it suitable for cutting thick sections of material with exceptional speed and accuracy. As a genuine Thermal Dynamics OEM part, it guarantees the tight manufacturing tolerances required to maintain the fluid dynamics and electrical conductivity essential for high-definition plasma arcs.

Optimized for Mild Steel and Oxygen

This specific electrode variant is tailored for Mild Steel (MS) applications utilizing Oxygen (O2) as the plasma gas. In high-amperage oxygen plasma cutting, the electrode undergoes immense thermal and chemical stress. The 21-1308 features a robust hafnium insert designed to withstand the oxidizing environment of the pure oxygen stream while delivering a stable, high-energy arc. This optimization ensures that operators achieve dross-free cuts with minimal edge bevel, significantly reducing secondary processing time in fabrication workflows.

Performance and Durability

At 400A, the integrity of the electrode is paramount to preventing torch failure and ensuring cut consistency. Thermal Dynamics utilizes advanced cooling geometries within the electrode body to dissipate the intense heat generated during the cutting process. This thermal management extends the lifespan of the consumable, allowing for longer continuous cutting cycles and reduced downtime for changeovers. The "UC" designation indicates its compatibility with Ultra-Cut technology, which modulates gas flows and current to produce laser-like cut quality on carbon steels.

Industrial Reliability

Supplied in a convenient pack of 5, these electrodes are essential for facilities running high-volume production lines. Using genuine Thermal Dynamics consumables protects the torch head from damage caused by catastrophic failure of inferior aftermarket parts. By maintaining the correct arc focal point and energy density, the 21-1308 electrode ensures that your 400A system operates at peak efficiency, delivering the clean, square edges that professional fabricators demand.
