4-2525-05 - Tweco 5ft Welding Leads Set for Thermal Dynamics Model 4A

OEM Replacement Leads for TDC Model 4A

The Tweco 4-2525-05 is a specialized 5-foot leads package designed for compatibility with the TDC (Thermal Dynamics) Model 4A welding system. As an essential component for power transmission in arc welding, this package ensures that the welding current is delivered efficiently from the power source to the workpiece. Manufactured to Tweco's rigorous standards, these leads utilize high-grade copper stranding to minimize voltage drop and resistance heating, ensuring stable arc characteristics even during extended use.

The assembly typically includes both the electrode holder lead and the work (ground) clamp lead, providing a complete solution for replacing worn or damaged output cables. The insulation jacket is formulated from durable, flexible materials capable of withstanding the harsh environment of industrial and shop settings, offering resistance to abrasion, cuts, sparks, and oil. The 5-foot length is specifically tailored for the portability and form factor of the Model 4A unit, making it ideal for bench work or confined space applications where long cables would be cumbersome.

Professionals in maintenance, repair, and fabrication rely on genuine Tweco/Thermal Dynamics parts to maintain equipment safety and performance. Using non-compliant or undersized leads can result in overheating and poor weld quality. This package comes pre-assembled with the appropriate connectors for the Model 4A, reducing downtime and eliminating the need for field termination. Whether for routine maintenance or critical repair, the 4-2525-05 leads package restores the electrical integrity of your welding setup.
