94433118 - Arcair K-3/K-5 Extreme & Tri-Arc Insulator and Screw Kit

Genuine Arcair Replacement Insulator for Heavy-Duty Gouging

The Arcair 94-433-118 Insulator Assembly is a critical replacement component designed to maintain the safety and performance of your manual gouging torches. Specifically engineered for the K-3 Extreme, K-5 Extreme, and Tri-Arc foundry torches, this assembly ensures that your equipment operates within safe electrical parameters. In the high-amperage environment of air carbon-arc gouging, the integrity of the torch's insulation is paramount. A compromised insulator can lead to stray arcing, damage to the torch body, and potential safety hazards for the operator.

This kit includes both the durable insulator block and the specific screw assembly required for secure installation. Manufactured by Arcair, the leader in air carbon-arc gouging technology, this OEM part guarantees a precise fit that aftermarket alternatives cannot match. The material used is highly resistant to the extreme heat and spatter generated during metal removal processes, ensuring longevity even in the harshest foundry or fabrication shop environments.

Regular maintenance of your gouging torch is essential for productivity. Over time, insulators can crack or degrade due to thermal cycling and mechanical impact. Replacing the insulator with the 94-433-118 assembly restores the torch to factory specifications, allowing for consistent airflow and efficient current transfer to the carbon electrode. Whether you are performing weld removal, back-gouging, or defect repair, trusting genuine Arcair parts ensures your operations run smoothly without unexpected downtime.
