K3001-2 - Lincoln Electric S-Series Interface Kit with TIG Solenoid

Technical Overview: K3001-2 S-Series Interface

The Lincoln Electric K3001-2 is a dedicated hardware interface kit engineered specifically for the Power Wave S350 and Power Wave S500 welding power sources. This component is critical for shops utilizing these power sources for multi-process applications, particularly where local control of SMAW (Stick), GTAW (TIG), and GMAW/FCAW (Wire) processes is required directly from the power source front panel. The kit physically integrates into the machine, expanding its I/O capabilities and user interface functionality to support a broader range of welding procedures without relying solely on wire feeder controls.

Integrated TIG Functionality
A primary technical feature of the K3001-2 is the inclusion of a TIG gas solenoid. In standard configurations, some power sources may rely on external gas management or valve-equipped torches for TIG welding. This kit embeds the solenoid control within the power source, allowing for pre-flow and post-flow timing managed by the machine's logic. This results in superior tungsten life and weld pool protection compared to manual valve systems. The solenoid integration is seamless, requiring no external power supplies or complex plumbing beyond the standard gas inlet and outlet connections provided.

Remote Connectivity and Control
The kit also equips the power source with a standard 12-pin Amphenol-style remote control connector. This receptacle is the industry standard for Lincoln Electric remote accessories, enabling the connection of devices such as the K870 Foot Amptrol or K963 Hand Amptrol. This connectivity is essential for critical TIG welding where real-time amperage adjustment is necessary to control heat input and crater fill. Furthermore, the interface panel allows for the selection and adjustment of process parameters locally, ensuring that the operator has full command over the machine's output characteristics regardless of the wire feeder configuration. This kit effectively unlocks the latent multi-process potential of the S-Series platform.
