Medium Frequency DC Spot Welding Machine with 1000Hz Inverter Frequency Intelligent Touch Screen Controller and 50KVA Rated Power

MF DC Spot Welder represents one of the newest resistant welding technologies. The key advantage is significant reduction in iron core material energy consumption, achieved by increasing the welding transformer frequency from standard 50/60Hz mains supply to 1000Hz.

Additionally, the commutation diode in the transformer subloop converts electrical energy into DC power for welding. This dramatically improves the inductance coefficient of the subloop while minimizing production costs, as inductance coefficient - a major factor in energy loss - becomes negligible in DC welding circuits.

• Advanced welding machine utilizing MF inverter principle, converting three-phase AC power to DC power
• DC welding current with no inductance, providing higher heat input/output efficiency and more reliable, stable welding quality
• Intelligent digital controller for precise, fast control of welding current with adjustment precision 20 times higher than AC machines
• Reduced production costs, energy savings, lower cable requirements, and minimized maintenance costs
• Energy storage in special inverter for better adaptation to power grid fluctuations
• Compact welding transformer with one-third the size and weight of AC machines
• Capable of welding aluminum and galvanized materials
• Ideal for welding three-layer metal sheets or very thin products

Ideal for various applications including sensors, LED and leads, copper foil and vanished wire, relays, watches, capacitive slugs and leads, copper wire, resistance pins, inductances, batteries and stabilizer links, sockets, and welding lightning with tungsten and molybdenum materials, silver contacts and copper sheets.
