94378283 - Arcair Tri-Arc 3/4-Inch Pad Washing Head Assembly

Heavy-Duty Foundry Gouging Head Assembly

The Arcair 94378283 is a specialized Head Assembly designed for the Tri-Arc foundry torch series. Engineered specifically for pad washing applications, this component is critical for operators tasked with removing metal pads, risers, and fins in high-production foundry environments. The assembly is configured to accept 3/4-inch (19.05 mm) carbon electrodes, a standard size for heavy metal removal tasks where deposition rates and removal speed are paramount.

Constructed to meet the rigorous demands of the metalworking industry, this head assembly ensures robust electrical contact and optimal airflow direction. In the air carbon arc gouging process, the efficiency of the air stream relative to the electrode is vital for clean metal removal; this genuine Arcair part maintains the precise geometry required for effective pad washing. By using OEM parts, facilities ensure that their Tri-Arc torches operate within safety parameters and maintain the high duty cycles expected in foundry operations.

The 94-378-283 assembly includes the necessary mechanical components to securely grip the electrode and withstand the intense radiant heat generated during operation. It serves as a direct replacement for worn or damaged heads on existing Tri-Arc units, minimizing downtime and maintaining production throughput. Whether used for defect removal or general surface preparation, this head assembly provides the durability and performance associated with the Arcair brand.

Proper maintenance of the torch head is essential for preventing arcing within the torch body and ensuring operator safety. This assembly is designed for straightforward installation, allowing maintenance teams to quickly refurbish torches and return them to service. It is compatible with standard Tri-Arc setups configured for the pad washing process.
