Induction Brazing of Copper Pipe with Handheld System​

The system features an advanced touchscreen control panel that enables operators to select language preferences, monitor real-time machine parameters, including inverter current and frequency, and precisely adjust power settings for different application requirements.​

Engineered for accessibility and precision, the system enables technicians to perform flawless brazing in previously inaccessible locations without disassembly or production stoppages.

The Accessibility Challenge

Technicians frequently encounter copper pipe joints in confined spaces—embedded within machinery, behind panels, or in overhead installations. Traditional torches struggle with consistent heat application in these scenarios, while fixed induction systems cannot reach the work area. The solution requires both power and flexibility in a compact format.

FOCO’s Mobile Brazing Solution

Our engineering team developed a complete handheld system that addresses these challenges:

• High-Frequency Precision: 10-30 KHz frequency range optimized for copper heating characteristics
• Integrated Cooling System: Built-in chiller unit eliminates external water connections
• Ergonomic Handling: Lightweight aluminum alloy construction with pivot mounts and overhead suspension
• Smart Control Interface: Integrated touchscreen for parameter adjustment and temperature monitoring

Brazing process

1. Select the appropriate coil configuration for the specific pipe diameter
2. Position the handpiece using the adjustable suspension system for optimal joint access
3. Set temperature and duration parameters via the intuitive touchscreen interface
4. Engage the trigger; the system delivers precise heating within 8-12 seconds
5. Internal cooling maintains safe external temperatures during operation

Technical Advantages

• Mobility: Complete portability for in-situ repairs without component removal
• Rapid Heating: Achieves brazing temperature (780°C) in under 12 seconds
• Consistent Results: Uniform heating profile ensures joint integrity
• Enhanced Safety: No open flames; automatic thermal protection safeguards both operator and workpiece
• Reduced Oxidation: Controlled induction environment minimizes surface contamination

Performance Data

Field tests demonstrate:

• 45% faster completion compared to torch methods
• 30% reduction in material waste
• Consistent joint quality across multiple operators
• Continuous operation capability for production environments
