Applications
Meltric WS Series connectors are used in heavy industrial welding environments where high-amperage welding cables must be connected and disconnected repeatedly and safely. They are commonly found in manufacturing plants, shipyards, steel fabrication facilities, and automated welding cells, where robustness and a secure mechanical lock matter as much as current capacity. The WS Series connector design allows welding cables to be swapped between machines or work stations without the need for permanent terminations, making them a standard choice for facilities running multiple welding processes or shared welding power sources. Meltric Corporation has been a recognized manufacturer of industrial-duty electrical connectors in the United States for decades.
This Meltric 4-0901-K WS Welding Connector has been inspected and is in good condition. Both the black thermoplastic male plug and the aluminum female connector body are present. The aluminum body shows some surface scuffing and minor handling marks consistent with storage; the male plug is clean with no cracks to the housing, though a faint hairline seam is visible at the bore face (visible in photos). Original Meltric Corporation box is included. Please view our photo set and contact us if you have any questions. Please note: We have multiple units in stock — yours may not be the one shown in the photos, however, it will be similar in condition and function.
