18650 Battery Special Spot Welding Machine Circuit Board for Farad Capacitor
Tax included.
Feature:
Capacitance requirements: 2.8V 3000F X2
Charging voltage: 5-5.6V, current: 2-20A
This product does not contain farad capacitors, and the circuit does not contain charging control, so the customer solves the capacitor charging problem by yourself.
This product is suitable for connection with 2 series farad capacitors (2.8V+2.8V). A single capacity of 3000F or more is recommended. The circuit depends on the single-chip microcomputer program for precise control and is divided into 5 power levels. It automatically detects the contact resistance of the welding pen, automatically triggers, passes 300A power tube X4 parallel output, no problem welding 0.15 nickel sheet.
Package includes:
1 x Spot Welding Machine Circuit Board
