SL2-35M - CK Safe-Loc 35 Male Dinse Adapter for Air Cooled TIG Torches

Technical Overview of the CK Worldwide SL2-35M SafeLoc Connector

The CK Worldwide SL2-35M is a precision-engineered gas-thru cable connector designed to interface air-cooled TIG torches with modern welding power sources utilizing Dinse-style receptacles. This unit is part of the Safe-Loc system, which prioritizes operator safety and connection integrity through a robust design architecture. The connector features a standard 35 Dinse male pin, measuring approximately 1/2 inch (12.8mm) in diameter, which is the industry standard for medium-to-heavy duty inverter and transformer-based power supplies.

The core function of the SL2-35M is to facilitate the transmission of both welding current and shielding gas through a single connection point, a configuration known as "gas-thru." This eliminates the need for separate gas lines running to the machine face, streamlining the setup for 1-piece power cable torches such as the CK9, CK17, and MR70 series. The internal gas path is sealed to prevent leaks, ensuring consistent shielding gas coverage at the weld pool, which is critical for maintaining weld quality and preventing porosity.

A distinguishing feature of this connector is its rugged poly-resin clamshell housing. Unlike basic rubber boots or exposed brass fittings, the Safe-Loc clamshell provides a hard, durable barrier that insulates the electrical connection from the environment. This design significantly reduces the risk of arcing against the machine case or workbench and protects the operator from accidental electrical contact. The housing is designed to withstand the harsh conditions of industrial environments, including impact and thermal stress.

Compatibility is broad across major equipment manufacturers. The SL2-35M is specifically calibrated for use with Lincoln Electric models such as the Invertec V160-T, V205-T, Precision TIG 225, and Squarewave TIG 175/200 series. It is equally compatible with Miller Electric units like the Syncrowave 180SD and Syncrowave 200. By converting standard threaded power cables to a quick-connect Dinse format, this adapter modernizes older torch setups and ensures seamless integration with current welding technology.
