Semi-Automatic Ultrasonic Terminal Welding Machine with 5000 W Generator WM-713

›

The WM-713 welds stranded copper wire directly onto terminals by 20 kHz ultrasonic vibration — no solder, no flux, no contact-resistance drift. Its 5,000 W generator covers gathered cross-sections under 30 mm² and closes each joint in 0.5 to 2 seconds under 0.2–0.8 MPa air. The English touchscreen stores recipes and shows counters, power, temperature and amplitude live, with quality monitoring and weld records built in. The pneumatic weld head sits on a 46 × 15 × 14 cm bracket beside a 58 × 18 × 46 cm generator cabinet; the set weighs 80 kg.

Specifications

Key features

• Metallurgical wire-to-terminal bonds replace solder pots and flux fumes — and the joint resistance stays put through vibration and thermal cycling
• 5,000 W of output closes gathered sections just under 30 mm² in 0.5–2 s, a class above what small wire splicers can handle
• Recipe storage on the English touchscreen changes terminal types in seconds, with weld records and a quality monitor for process audits
• Separate generator cabinet keeps the electronics off the press, so the compact weld head fits tight cells while the screen sits at eye level

What it processes

• Welding battery, motor and inverter lead wires onto lugs and terminals in EV and automotive harnesses
• Stranded wire and braid terminations in switchgear and energy-storage assemblies
• Replacing solder or crimp terminations where low, stable contact resistance is specified

Suited for: welding stranded copper wire onto terminals and lugs with gathered sections under 30 mm² — battery, motor and inverter leads where solder is banned and crimp resistance drifts too much. Not suited for: wire-to-wire splicing below 20 mm² — for that, pick the WM-711 ultrasonic wire welding machine, the dedicated 3,000 W splicer that covers 0.75–20 mm² joints at lower cost — nor plastics or any solder and tinning work, which live with the other wire soldering and welding machines.

Send your terminals plus 2–3 meters of each wire and we weld your actual joints on video — including a peel-back of the weld — before you commit. Terminal welds like these anchor the power side of an EV wire harness line.
