K1622-7 - Lincoln Electric Twist Mate Plug 10-25 with Gas Pass

Technical Overview of the Lincoln Electric K1622-7

The Lincoln Electric K1622-7 is a specialized male cable connector designed for precision welding applications requiring gas flow integration. Belonging to the Twist Mate family of connectors, this unit utilizes the industry-standard Dinse 10-25 sizing convention, making it compatible with a wide range of compact inverter power sources, specifically those within the Lincoln Electric Invertec series. The defining characteristic of this SKU is its "Gas Pass" capability, which allows shielding gas to flow directly through the connector body, facilitating a streamlined connection for gas-cooled TIG torches without the need for external gas hoses at the machine terminal.

Constructed from high-grade brass, the connector ensures minimal electrical resistance and optimal current transfer, which is critical for maintaining stable arc characteristics in TIG welding. The exterior is shielded by a durable, heat-resistant rubber boot that provides electrical insulation and protection against impact and abrasion common in industrial environments. The Twist Mate locking mechanism employs a cam-lock action, ensuring that once the connector is inserted and twisted, it remains securely fastened to the female receptacle, preventing accidental disconnection during operation.

This component is essential for fabricating custom TIG power cables or replacing damaged connectors on existing torch assemblies. It supports cable cross-sections typically ranging from 10mm² to 25mm², accommodating the amperage ranges standard for portable inverter welders. The K1622-7 is engineered to meet strict OEM specifications, ensuring perfect mating with Lincoln Electric power sources and preventing gas leaks at the connection point.
