OVERVIEW

Extend Your Reach with the Tweco SPC-2040

When your welding leads come up short, or you need to fix a cut in your cable quickly without hauling the whole rig back to the shop, the Tweco SPC-2040 Cable Splicer is the tool for the job. Designed for professional welders who demand reliability and ease of use, this splicer lets you connect 2/0, 3/0, or 4/0 cables in minutes. Forget about hunting for a heavy hydraulic crimper; all you need is a hex key to secure the connection.

Built for the Job Site
Welding environments are tough on equipment, and your connections are the weak link if not done right. The SPC-2040 uses a solid copper alloy body that handles high amperage without getting hot, ensuring your arc stays smooth and consistent. The ball-point screws dig deep into the copper strands of your cable, crushing through dirt and oxidation to make a perfect electrical connection every time. This means less voltage drop and better welds, even when you are running hundreds of feet of lead.

Safety and Durability
Safety is paramount, and a bare metal splice is a hazard you can't afford. This kit comes complete with a rugged insulating cover that slides over the splice, protecting it from dragging across the floor, getting crushed by equipment, or shorting out against your workpiece. Whether you are extending leads for a structural steel job or repairing a damaged cable in the field, the Tweco SPC-2040 gets you back under the hood faster with a connection you can trust.

FAQ

The Tweco 9610-1101 (Model SPC-2040) is designed to fit welding cables sized 2/0, 3/0, and 4/0 AWG.

No, this is a mechanical splicer that uses ball-point set screws. You only need a hex key (Allen wrench) to tighten the screws onto the cable.

Yes, the product comes as a complete set including the copper body, set screws, and the insulating cover.

Yes, because it uses a screw-type connection, you can loosen the screws to remove the cable and reuse the splicer on other cables if necessary.

The splicer body is made from a high-conductivity copper alloy to ensure efficient current transfer.

The cover typically slides over the metal body. In many Tweco designs, the screws that hold the cable also help anchor the cover, or it is a friction fit designed to stay in place during use.

While physically possible if the size matches, mechanical lugs are generally optimized for copper cable. Aluminum has different thermal expansion properties and may require periodic re-tightening or anti-oxidant compound. Always check local electrical codes.

The amperage rating is generally determined by the cable size used. Since it fits up to 4/0 cable, it can handle the typical amperage associated with that cable size (often up to 400-500 amps depending on duty cycle).
