94170178 - Arcair K2000/K3000 Male Connector 94-170-178

Technical Overview: Arcair 94-170-178 Male Connector

The Arcair 94-170-178 Male Connector is a critical mechanical and electrical component for the K2000 and K3000 manual gouging torches. In the air carbon-arc gouging process, the torch must deliver high amperage current to the carbon electrode while simultaneously directing a stream of compressed air to eject molten metal. This connector serves as the interface point, typically associated with the 70-088-10 cable assembly, ensuring that both power and air are transmitted efficiently from the cable to the torch head.

Constructed from high-conductivity materials, likely a durable brass alloy, this male connector is designed to resist the thermal cycling and mechanical stress inherent in gouging applications. Over time, connectors can become pitted or threaded surfaces can wear down, leading to increased electrical resistance. High resistance at connection points generates excess heat, which can damage the torch handle, melt insulation, and pose a safety hazard to the operator. Replacing the connector with this OEM part restores the low-resistance path necessary for stable arc performance.

Installation involves securing the connector to the appropriate cable or torch body port. It is vital to ensure threads are clean and not cross-threaded during assembly to maintain an airtight seal for the compressed air channel. This part is specifically referenced for use with the 70-088-10 assembly, ensuring compatibility with the specific thread pitch and bore size used in the K2000 and K3000 series. Regular inspection of this connection point during routine torch maintenance is recommended to prevent unexpected downtime.
