Inline Auto Flame Brazing Welding Equipment for Air-conditioning Evaporator and Condenser
Working Principle:
By providing automated soldering process, precisely controlling welding heating time, and controlling the gas flow by using a mass flow controller to achieve to precisely control the temperature of the soldering and solder bath, to ensure the stability and consistency of welding quality.
Indexing by the sophisticated automatic divider, can ensure that each welding angle error does not exceed 15 ".
The combustion gas flow, welding time and other parameters can be adjusted in the production process, and various process parameters can be real-time monitored; The preset process parameters can be stored (maximum: 30 groups), can call the appropriate preset process parameters directly according to the different pieces to be welded.

Main Function:
1. Automatically ignite and extinguish fire; Automatically switch the strength of the flame; keep flame stable, avoid tempering
2. With faulty alarm and self-diagnostic functions
3. Gas concentration detection function: when the gas concentration reaches to the 50% of explosive limit, the system will automatically shut down or close the gas valve, and alarm occurs.
4. Extinguishing with nitrogen: can avoid deflagration.
5. Power-off protection: the equipment will automatically fill in nitrogen
6. Emergency button: In urgent cases, the electrical and pneumatic system can be shut-off immediately, and starts extinguishing protection.
Benefits analysis:
Every 8 hours of production can reach 2500 pieces or more. The device can operate 20 hours continuously. Calculated in accordance with professional welders’ stage salaries, the investment cost of the equipment can be recovered by one year.
