Product Overview

The RX-HB26KV Medium Frequency Seam Welding Machine is a high-performance resistance welding system utilizing advanced MF inverter technology. Compared to traditional power-frequency welders, it offers smooth current output, superior thermal efficiency, high power factor, excellent energy savings, and minimal impact on the power grid. By applying continuous pressure and high-frequency pulse currents via roller electrodes, it forms leak-proof, high-strength continuous or overlapped welds. It is widely used in hardware, home appliances, automotive water tanks, mufflers, and stainless steel container manufacturing.

Key Features & Technical Advantages

 MF Inverter Control System
Operates at 1000 Hz high frequency with rapid current adjustment response and exceptional control accuracy up to ±2%, ensuring premium weld seam consistency.
 Multi-Stage Heating Programs
Includes preheating, welding, and tempering (slow cooling) stages to effectively eliminate hardening tendencies and prevent thermal cracking in high-strength steel or stainless steel.
 Heavy-Duty Mechanical Frame
Constructed with 20 mm high-strength steel plate body for rigid, anti-deformation stability. Provides consistent electrode alignment and steady pressure application.
 Microcomputer Touch Interface
Intuitive microcomputer touch control panel allows easy parameter setting and complete diagnostic protection against overheating, overcurrent, and abnormal air pressure.
 Efficient Water Cooling
Forced water-cooling circulation system protects both roller electrodes and transformers, enabling long-term continuous operation at a 50% duty cycle with high wear resistance.
