DZN-160 welding thick workpieces and high conductivity metal medium frequency spot welder

The DZN-160 is a medium-frequency spot welder engineered for welding thick workpieces and high-conductivity metals. Controlled via an intuitive touchscreen, the unit displays real-time welding currents and issues immediate fault alerts, delivering reliable, repeatable spot welds for industrial production lines in sectors such as new energy vehicles, home appliances, and construction.

Detailed description (features & advantages)

• Touchscreen control & monitoring — Integrated touchscreen HMI shows live welding current values and system status; provides clear fault alerts for fast troubleshooting and reduced downtime.
• Medium-frequency inverter control (1000 Hz) — The control system inverts the input to 1000 Hz, raising the operating frequency of the welding transformer to improve dynamic response and control of the weld energy.
• Increased secondary loop inductance — Frequency adjustment results in an elevated secondary loop inductance, which optimizes the energy delivery profile for thicker workpieces and highly conductive materials.
• Excellent performance on high-conductivity metals — Specifically suited for aluminum, galvanized steel, and other low-resistance materials where conventional low-frequency spot welding struggles to achieve consistent penetration.
• Improved weld quality and consistency — Higher frequency and tuned inductance reduce uncontrolled current spikes, producing stable nugget formation, better fusion on heavy sections, and tighter process repeatability.
• Applications versatility — Designed for demanding production environments: battery pack assemblies and structural components in new energy vehicles, casing and structural welds in home appliances, and sheet-joining tasks in construction hardware.
• Operational efficiency & reduced thermal distortion — Controlled energy delivery concentrates heat at the weld zone, minimizing heat-affected areas and lowering the risk of warpage on thick panels.
• User-focused maintenance and safety — Real-time monitoring, fault reporting, and a simplified control interface make daily operation, preventive maintenance, and operator training straightforward.
