K1622-1 - Lincoln Electric Twist Mate Adapter for PTA-9/17 Torches

Technical Overview: Lincoln K1622-1 Twist Mate Adapter

The Lincoln Electric K1622-1 is a specialized adapter kit designed to interface 1-piece air-cooled TIG torches with power sources utilizing combined gas/power output receptacles. This unit is specifically calibrated for use with PTA-9 and PTA-17 model torches, adapting their standard cable fittings to a 35mm DINSE (Twist Mate) gas-through connector. This configuration is critical for operators using machines like the Lincoln Square Wave TIG 275, where the gas solenoid output is integrated into the power terminal.

Operational Specifications

The adapter is rated for a maximum output of 150 Amps, aligning with the duty cycles and amperage limits typical of the PTA-9 (125A) and PTA-17 (150A) torch series. It facilitates a direct connection for the power cable while simultaneously routing shielding gas through the center of the DINSE connector. This internal gas path removes the need for a separate gas hose connection at the front of the machine, reducing cable clutter and potential leak points.

Compatibility and Installation

This component is engineered for air-cooled applications only. It accepts the standard threaded power pin from 1-piece torch cables and converts it to the male Twist Mate end. The "35mm" designation refers to the DINSE connector size standard (typically compatible with 35-50mm² cable sockets). It is not compatible with water-cooled torches or 2-piece cable assemblies that require separate power lugs.

Construction and Performance

• Connector Type: Male Twist Mate / 35mm DINSE with Gas-Through port.
• Input Thread: Standard 3/8"-24 RH (typical for 9/17 1-piece cables).
• Insulation: High-temperature rubber boot protects against electrical shock and debris.
• Conductivity: Machined brass components for minimal voltage drop and resistance heating.

For industrial MRO and fabrication environments, the K1622-1 provides a robust solution for maintaining fleet compatibility between various torch models and Lincoln power sources. Ensure your power source is equipped with a gas-through female receptacle before installation.
