The Arcair 94-378-368 Replacement Head and Screw is a critical maintenance component designed specifically for the industry-standard K4000 and K-3 Extreme air carbon-arc gouging torches. In the demanding environment of heavy metal fabrication and gouging, the torch head is subjected to intense heat, spatter, and mechanical stress. Over time, the seating surfaces can wear down, and threads can become stripped, leading to poor electrical conductivity and inefficient operation. This genuine Arcair replacement part ensures that your equipment continues to perform at the high level required for professional applications.
When dealing with high-amperage gouging applications, the quality of your contact surfaces is paramount. This replacement head is manufactured from durable copper alloy materials that offer excellent thermal and electrical conductivity. By using genuine OEM parts, you ensure that the fit and finish match the original specifications of your K4000 torch. This precise fit is essential for maintaining the correct air stream alignment around the carbon electrode, which is the key to clean, effective metal removal.
This head assembly is engineered to fit the Arcair K4000, the K-3 Extreme, and compatible models like the Radnor Pro4000. The kit includes the head unit and the necessary screw to secure it to the torch body. Installation is straightforward, allowing operators to perform field repairs quickly and minimize costly downtime. Whether you are working in a foundry, a shipyard, or a structural steel shop, keeping a spare head assembly on hand is a best practice for maintaining continuous productivity.
