94378286 - Arcair Tri-Arc 1/2-Inch Pad Washing Head Assembly

Arcair 94378286 Head Assembly for Tri-Arc Foundry Torches

The Arcair 94378286 is a specialized Head Assembly designed specifically for the heavy-duty Tri-Arc foundry gouging torch. This component is critical for operators performing pad washing applications, a process used to remove excess metal, such as riser pads or fins, from castings to leave a smooth, flat surface. Unlike standard gouging heads designed for deep groove creation, this pad washing head is engineered to orient the electrode and airflow in a manner that facilitates wide, shallow metal removal, ensuring the underlying base metal remains undamaged while achieving the desired surface finish.

Constructed to withstand the extreme heat and abrasive conditions typical of foundry environments, this head assembly is rated for use with 1/2-inch carbon arc gouging electrodes. The robust design ensures secure electrode clamping and consistent electrical conductivity, which are vital for maintaining a stable arc during high-amperage operations. The assembly also plays a crucial role in directing the compressed air stream. In air carbon arc gouging, the air stream blows the molten metal away from the work area; this head assembly ensures that the air is directed efficiently to clear slag immediately, preventing re-solidification and ensuring a clean wash.

Maintenance of the torch head is essential for safety and performance. Over time, the intense heat and spatter involved in gouging can degrade the head assembly, leading to poor air flow, electrode slippage, or reduced conductivity. Replacing a worn head with the genuine Arcair 94378286 ensures that your Tri-Arc torch operates at peak efficiency. This part is a direct OEM replacement, guaranteeing a perfect fit without the need for modification. It is an indispensable component for foundries looking to maintain high throughput and quality in their finishing departments.

By utilizing genuine Arcair parts, users benefit from the engineering expertise of the industry leader in air carbon arc gouging. The 94378286 head assembly supports the Tri-Arc's reputation as a workhorse in the metal fabrication and casting industries, providing reliable performance shift after shift. Whether you are washing pads on steel castings or performing general surface cleanup, this head assembly provides the control and durability required for professional results.
