Precision welding of automotive batteries and wiring harnesses
Complete Equipment Series Tailored to Your Processing Needs
From micro-wire harness splicing to heavy-duty high-voltage terminal welding, we provide the ultimate industrial bonding solutions.
Our EVC series is designed for wire harness welding, while the EVT series handles the welding of wire harnesses to terminals; both series can accommodate wire harnesses and terminals of various gauges. Additionally, we offer the EMPT series—an electromagnetic pulse system—to address more complex connection challenges.
