Equipment Introduction

Designed specifically for precision industrial welding applications, the RX-HB80K effectively addresses common pain points of traditional welding equipment, such as workpiece deformation, severe spatter, demagnetization, heat burn-through, and high power consumption.

It serves as the ultimate high-efficiency welding solution across hardware processing, automotive components, home appliance sheet metal, and electronic elements.

Industry Pain Points & Medium Frequency Solutions

Traditional Welding Bottlenecks
  • Thermal Deformation & Burn-Through: High heat input causes warping, distortion, and base material burn-through in thin sheets[cite: 1].
  • Excessive Spatter & Secondary Grinding: Violent spatter creates burrs and bumps, requiring costly manual secondary grinding[cite: 1].
  • High-Temperature Demagnetization: Risks demagnetizing motor rotors and permanent magnets, causing torque drop and operational noise[cite: 1].
  • Grid Impact & High Energy Usage: Single-phase AC power causes severe power grid fluctuations, low power factor, and high electricity bills[cite: 1].

RX-HB80K MFDC Breakthroughs
  • Minimal Heat-Affected Zone: 1000Hz inverter technology with millisecond-level precision temperature control prevents deformation and demagnetization[cite: 1].
  • Significant Energy Savings: 3-phase balanced power input achieves a power factor > 0.95, reducing power consumption by 30%-45%[cite: 1].
  • Spatter-Free High Quality: Closed-loop control ensures uniform weld penetration without spatter or burrs, eliminating secondary grinding[cite: 1].
  • Grid-Friendly Operation: Balanced load distribution avoids single-phase grid overload and maintains stable line voltage[cite: 1].

Main Applications & Workpieces

1. Fasteners & Stampings

• Nuts & Bolts: Automotive and industrial four-projection, hex flange, and round nuts welded to sheet metal[cite: 1].
• Studs & Leads: Precision projection welding for electronic bases, grounding studs, and connection terminals[cite: 1].

2. Automotive Components

• Structural Parts: Multi-point projection welding on high-strength steel (HSS/AHSS) door locks, seat rails, and cabin plates[cite: 1].
• Chassis Assemblies: Precision welding for clutch discs, drive shaft brackets, and brake lining supports[cite: 1].

3. Home Appliances & Cabinets

• Sheet Metal Enclosures: Compressor mounting plates, inner tub supports, and switchgear cabinets[cite: 1].
• Hinges & Handles: Mark-free/low-mark projection welding for door hinges and flush-mounted handles[cite: 1].

4. Dissimilar Metals

• Special Materials: Copper-to-steel, brass-to-steel, and stainless-to-low-carbon steel joining[cite: 1].
• Precision Components: Silicon steel sheets, metallic gaskets, galvanized sheets, and wire mesh[cite: 1].

Core Technological Advantages

01

1000Hz Millisecond Control

Standard AC power operates at 50Hz (20ms cycle), while 1000Hz MFDC operates at 1ms cycles for ultra-precise current control, ensuring exact projection melting[cite: 1].

02

Energy Savings & Grid Friendly

Uses balanced 3-phase 380V input with a power factor ≥0.95[cite: 1]. Thermal efficiency is significantly increased, cutting electricity costs by 30%-50%[cite: 1].

03

Zero Spatter & Long Electrode Life

MFDC output eliminates AC zero-crossing points[cite: 1]. High synchronization between pressure and current prevents spatter and reduces electrode wear by over 50%[cite: 1].

04

Smart Automation Integration

Equipped with a Weinview touch screen and Siemens PLC control system[cite: 1]. Reserved expansion interfaces support seamless connection to robotic production lines[cite: 1].
