Product Overview

The RX-HB40KV Medium Frequency Seam Welder is an advanced resistance welding machine engineered with cutting-edge MF inverter technology. Compared with traditional line-frequency welders, it offers stable output current, superior thermal efficiency, a high power factor, exceptional energy saving, and minimal impact on the power grid. By delivering continuous high-frequency pulse currents under roller electrode pressure, it produces airtight, high-integrity continuous or overlapping weld seams.

Key Features & Specifications

1000 Hz MF Inverter Control

Delivers ultra-fast current response speed with high control accuracy (±2%) for consistent, premium seam welds.

Multi-Stage Heating Program

Supports pre-heating, welding, and tempering (slow cooling) stages to eliminate hardening tendencies and prevent weld cracking.

Heavy-Duty Mechanical Structure

Constructed with a 20 mm thick high-strength steel plate body to guarantee optimal rigidity, minimal deformation, and electrode alignment.

Intelligent Digital Interface

Equipped with an intuitive microcomputer touch panel featuring auto-diagnostics for overheating, overcurrent, and air pressure anomalies.

Forced Water Cooling System

Ensures stable operation at a 50% duty cycle with high wear resistance and extended electrode wheel service life.
