94378267 - Arcair Tri-Arc 1/2-Inch Upper and Lower Head Assembly Replacement

Arcair 94-378-267 HD Upper & Lower 1/2" Tri-Arc Head Assembly

The Arcair 94-378-267 is a premium replacement head assembly designed specifically for the Arcair Tri-Arc foundry torch. This heavy-duty component includes both the upper and lower head sections, providing a complete solution for maintaining your gouging equipment. Manufactured from a robust copper alloy, this head assembly is engineered to withstand the extreme thermal stress and physical demands typical of foundry environments.

Reliability is critical in industrial metal removal, and the Tri-Arc system is a staple in the industry for its power and durability. This replacement head is machined to precise tolerances to hold 1/2-inch (12.7mm) pointed or jointed carbon electrodes securely. The secure grip ensures consistent electrical contact and arc stability, which are essential for efficient gouging, pad washing, and defect removal. Poorly fitting aftermarket parts can lead to arcing, overheating, and premature torch failure, making this genuine Arcair part a vital investment for equipment longevity.

One of the key features of this assembly is its airflow design. It features four distinct air holes machined directly into the copper body. These holes are positioned to direct a powerful stream of compressed air parallel to the electrode, effectively blowing away molten metal during the gouging process. This efficient metal removal capability is what makes the Tri-Arc system so effective for fin removal and piercing applications.

Installation of the 94-378-267 is straightforward, allowing maintenance teams to quickly swap out worn components and return the torch to service with minimal downtime. By replacing both the upper and lower sections simultaneously, operators ensure uniform wear and alignment, further enhancing the performance of the torch. Whether you are performing general purpose cleaning or heavy-duty defect removal, this Arcair head assembly delivers the performance professionals trust.
