Product Features
PLC-based control system ensuring stable welding performance with automatic frequency tracking
Flux-free welding process; ultrasonic vibration effectively removes surface contamination and oxide layers
No surface pre-treatment required; welding can be completed without solder or chemical additives
Short welding cycle time, typically completing a weld within 0.1–2.5 seconds
Low heat input; welding temperature remains below the metal melting point, preserving material properties
Excellent electrical conductivity after welding with very low contact resistance
Strong and reliable weld strength with good consistency
Low noise, simple operation, easy maintenance, and long service life
Safe and environmentally friendly operation without sparks, smoke, or harmful emissions
