OVERVIEW

Restore Your Gouging Torch Performance

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.

Genuine Arcair Quality

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.

Compatibility and Installation

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.

Key Benefits

  • Optimal Conductivity: Restores the electrical connection to the electrode for stable arcs.
  • Durability: Built to withstand the harsh conditions of air carbon-arc gouging.
  • Perfect Fit: Designed specifically for K-series torches to ensure safety and performance.

FAQ

This head is compatible with Arcair K4000, K-3 Extreme, and Radnor Pro4000 gouging torches.

No, this part number typically includes the head and the screw. Insulators are usually sold separately.

Over time, the head can become pitted, threads can strip, or it can deform from heat, leading to poor conductivity and loose electrodes.

Yes, this is the genuine Arcair 94-378-368 replacement part.

It is made of a high-durability copper alloy designed for electrical conductivity and heat resistance.

The K4000 and K3000 share many similarities, but it is best to check the specific parts diagram. This is explicitly listed for K4000 and K-3 Extreme.

Yes, the description confirms it includes the replacement head and screw.

The head holds the carbon electrode in place and helps direct the air stream for the gouging process.
