OVERVIEW

Genuine Arcair 20Z08 75-Degree Head Assembly

The Arcair 20Z08 is a premium replacement head assembly designed specifically for the industry-standard K3000 and K4000 air carbon arc gouging torches. Manufactured by ESAB under the Arcair brand, this component is critical for maintaining the structural integrity and operational efficiency of your manual gouging system. The head assembly serves as the primary conduction point for the high amperage required in gouging applications while simultaneously directing the compressed air stream necessary to blow away molten metal.

Engineered with a 75-degree angle, this head offers the standard ergonomic configuration preferred by most operators for general-purpose gouging in flat, horizontal, and overhead positions. The angle is calculated to reduce wrist strain while maintaining the optimal electrode-to-workpiece orientation. The body is machined from a high-grade copper alloy, selected for its superior thermal and electrical conductivity, ensuring that the torch runs cooler and maintains a stable arc even during extended duty cycles.

Failure to replace a worn or damaged head can lead to poor air flow, overheating, and potential damage to the torch cable assembly. The 20Z08 ensures a precise fit with Arcair insulators and handle assemblies, preventing air leaks that can compromise the gouging groove quality. This part is an essential spare for maintenance departments in foundries, shipyards, and steel fabrication shops where K-series torches are heavily utilized.

FAQ

The 20Z08 head assembly is designed to fit Arcair K3000 and K4000 manual gouging torches.

No, the 20Z08 is typically the head assembly itself. Insulators and other hardware are usually sold separately or reused if in good condition.

This head features a 75-degree angle, which is the standard configuration for most general gouging applications.

Over time, the head can become pitted, threads can wear, or air passages can clog, leading to overheating, poor conductivity, and inefficient metal removal.

Yes, this is a genuine Arcair (ESAB) part, ensuring the highest quality and compatibility with your equipment.

No, the K3000/K4000 series are for surface applications. Underwater gouging requires the Sea-Dragon or similar specialized torches.

It is manufactured from a high-grade copper alloy to withstand high heat and conduct electricity efficiently.

Disconnect power, remove the insulators and the old head from the cable assembly, clean the connection points, and install the new head ensuring a tight fit before replacing insulators.
