16DA4004A-002 - Tweco Enclosed Plug-In Control Relay

Reliable Control for Industrial Welding Equipment

The Tweco 16DA4004A-002 Enclosed Plug-In Relay is a critical component designed for the maintenance and repair of industrial welding power sources and wire feeders. In the demanding environment of a fabrication shop, internal electrical components must withstand not only frequent cycling but also the potential ingress of airborne particulates. This relay features a robust enclosed housing that shields the internal switching contacts from dust, metal shavings, and other contaminants, significantly enhancing its service life and reliability compared to open-frame alternatives.

As a plug-in style component, this relay is engineered for efficiency in maintenance operations. When a control circuit failure occurs, minimizing downtime is paramount. The plug-in design allows maintenance personnel to swap out a faulty unit rapidly without the need for soldering or complex rewiring, provided the matching socket is intact. This specific part is manufactured to meet the precise electrical specifications required by Tweco and compatible welding systems, ensuring that control signals for triggers, gas solenoids, or contactors are managed accurately.

Using genuine replacement parts like the 16DA4004A-002 ensures that your equipment continues to operate within its original design parameters. Generic substitutes may not offer the same coil resistance or contact rating, which can lead to premature failure or erratic machine behavior. This relay provides the assurance of OEM quality, restoring your welding equipment to full functionality and helping to maintain production schedules.
