20 kHz / 5000 Watt Ultrasonic Terminal Welding Machine is a powerful solid-state ultrasonic metal welding system built for heavy-duty terminal-to-wire and terminal-to-strip welding operations. Designed for industries where precision and high-strength connections are crucial—such as automotive wire harnesses, EV battery systems, charging infrastructure, solar energy, aerospace, switchgear, and industrial electrical assemblies—this machine ensures unmatched performance and long-term reliability.

With its 5000 Watt high-power ultrasonic generator, the machine delivers intense vibrational energy to create a clean, homogeneous bond between terminals and conductors without solder, flux, or excessive heat. This ensures superior conductivity, low resistance, and a long-lasting mechanical joint.

Its advanced digital microprocessor-based control system, automatic amplitude adjustment, energy monitoring, and real-time frequency tracking deliver repeatable production quality. The reinforced welding head and air/water cooling options make it suitable for continuous high-output production lines.

Engineered for manufacturers who demand strength, precision, stability, and durability, this 5000W ultrasonic terminal welder is ideal for large-scale industrial environments and automation lines.
