The QianLi Macaron Spot welding machine is a portable mini welder, essential for welding battery laminates and micro-objects. Ideal for soldering the old flex of an old original iPhone battery to a new iPhone battery (without flex). The built-in rechargeable battery makes this unit fully portable.

Key Features:

• Voltage output: 4.2V (Max)
• Current output: 650A (Max)
• Designed current: 1000A (Max)
• Charging port: Type-C
• Input: 5V/2A
• Dual pulse welding: First emits a preheat pulse and then the main welding pulse, which is stable and reliable
• Color display with real-time parameter settings

The machine has a special clamp base for welding without requiring an external handle. The new integrated design with a color display allows visual depiction of welding parameters. The base is covered on one side with red copper, preventing damage to the BMS board. Heat-resistant silicone improves stability during use.
