Key Advantages of Our Stainless Steel Pan Brazing Machine
1. Intelligent Control System for Consistent Brazing Quality
At the heart of our power supply cabinet is an Atmel-based microcontroller, complemented by advanced large-scale integrated circuits. This hardware-software synergy delivers superior control precision compared to conventional discrete component or standard IC-based systems. The result is ±1°C temperature control accuracy and consistent weld quality across every production batch.
2. User-Friendly Operation with Dual-Mode Flexibility
The operating table features an intuitive layout for easy handling. The front panel provides:
Digital status displays on both sides for real-time working parameters
Clear fault indicators for quick diagnostics and minimal downtime
Manual & Automatic operating modes, giving operators flexibility to switch based on production needs
The split left/right hydraulic stations ensure that a fault on one side doesn't interrupt production on the other - a critical feature for maintaining uptime.
3. Built-In Voltage Stabilizer - Save Secondary Investment
Most competitors require you to purchase a separate voltage regulator after buying their equipment, adding significant secondary costs. We've integrated a high-precision voltage stabilizer directly into our system. This ensures:
Stable heating power regardless of grid fluctuations
Consistent weld quality without rejects caused by voltage variations
Up to 15% longer IGBT lifespan due to protection from power surges

Operating table technical parameters: It mainly consists of a turntable, indexing table, induction head, motor, hydraulic cylinder, and hydraulic components.
1) Two turntables; two welding induction heads, each with a heating axis and two free axes for easy workpiece loading, unloading, and placement.
2) The mechanical rotation mechanism includes an asynchronous motor, a reducer, and an indexing table.
3) The hydraulic lifting mechanism includes a hydraulic station (motor, hydraulic pump, solenoid valve, etc.) and a hydraulic cylinder.
4) Heating mode: Manual/Automatic. In automatic mode, the lifting, heating, lowering, and rotating operations are performed automatically and continuously, with heating time set by the operator. The welding diameter range is 100- 400 mm. 3. Water Cooling System:
This system is used to cool the high-frequency power supply and induction head and consists of a water pump, water tank, and heat exchanger.
1) Water Pump: 4 kW motor, 44-meter head, and 8 tons/hour flow rate.
2) Water Tank: Welded stainless steel plate, 0.3 cubic meter capacity, equipped with a level sensor and return water filter.
3) Heat Exchanger: Stainless steel plate heat exchanger, 5 cubic meters capacity.
4) Internal water is provided by Party A, preferably distilled water, but purified water is also acceptable and may be replenished regularly.
5) External water is provided by the user and can be clean tap water, with a temperature below 35°C and a flow rate of at least 90 liters/minute.

Main Applications: For brazing the sandwich bottom of stainless steel cookware
The stainless steel pan brazing machine solves the disadvantage of poor thermal conductivity of single stainless steel while retaining the advantages of stainless steel's resistance to rust and its health and environmental protection. It is the core equipment for producing high-quality cookware, including the cookware as follows:
Stainless steel cookware: Welding composite bottoms for soup pots, frying pans, and woks.
Rice cooker lining: Welding the stainless steel lining to the aluminum outer layer.
Stainless steel kettle: Welding the kettle body to the thermally conductive bottom.
Other dining utensils: Containers requiring composite thermal conductivity, such as milk pans and thermos bottoms.
