OVERVIEW

Reliable Power Connections with Tweco T-120

The Tweco T-120 Solder Lug (Part No. 9520-1107) is a premium copper alloy terminal designed to provide a secure and highly conductive connection for your welding cables. Engineered by Tweco, a leader in welding accessories, this lug is specifically sized for 1/0 and 2/0 gauge welding cables, making it an essential component for fabricating new leads or repairing existing equipment.

Unlike mechanical or crimp-style lugs that can loosen over time due to thermal cycling, the T-120 is designed for a solder connection. This ensures a permanent bond between the cable strands and the lug, significantly reducing electrical resistance and heat buildup at the connection point. The lug features a flared cable entry, which simplifies the process of inserting the stripped cable end, ensuring all strands are captured neatly before soldering.

The T-120 features a 17/32-inch stud hole, perfectly sized to fit standard 1/2-inch studs found on most welding power sources and grounding clamps. Its flat contact surface ensures maximum area engagement for efficient current transfer. Whether you are setting up a shop welder or maintaining a fleet of portable machines, the Tweco T-120 offers the durability and performance professional welders demand.

FAQ

The T-120 lug is designed to fit 1/0 and 2/0 gauge welding cables.

The stud hole diameter is 17/32 inches, which is designed to fit a standard 1/2-inch stud.

While some users may attempt to crimp it, the T-120 is specifically designed as a solder lug. Soldering provides the intended mechanical strength and electrical conductivity.

It is made from a high-conductivity copper alloy.

No, the T-120 is sold as the bare metal lug only. Cable covers or heat shrink must be purchased separately if insulation is required.

Strip the cable insulation, insert the exposed copper strands into the flared end of the lug, and apply heat and solder to create a solid bond.

This product is typically sold individually (1 per each).

The internal part number is 9520-1107, and the model number is T-120.
