Welcome to our store! 1. For Spot Welders: This intelligent spot welding control board supports spot welding of 0.1-0.3 mm nickel sheets throughout the process, saving time and effort. 2. Intelligent Chip: Using an intelligent logic control chip to intelligently calculate battery power, the control board has stable performance and safer operation. 3. Multiple Functions: Supports magnification adjustment, capacitance adjustment, and power selection for 6 gears, with low and over-power warning function (prohibits welding). 4. Current Range: The spot welding control board uses 6 original MOS tubes, the maximum stable current is 1800A, with a 100A-900A wide welding current range. 5. Welding Mode: Standard automatic welding mode, automatic sleep in 8 minutes without operation, the control module is safe to use, has good feasibility. Item Type: Spot Welding Control Board Product Model: DHJ 02B Operating Voltage: 6.5-16V Operating Current: <20mA Standby Power Consumption: <0.5mA Recommended Operating Temperature: -10-60 ℃ Peak Welding Current: Maximum 1800A Smart Sleep: Automatic sleep after 8 minutes of inactivity Welding Mode: Standard automatic welding mode Welded Nickel Sheet Thickness: 0.1-0.25 mm (related to battery discharge energy) Common Power Supply: High-rate lithium battery, high-rate lithium iron phosphate, and other lithium batteries More Power Options: 1. 12V 30-65Ah battery has good performance and low internal resistance (internal resistance is less than 10 milliohms), discharge current is greater than 100A. For example, a 12V car starting battery. 2. 4000mah-10000mah, 30-70C, 2S 3S 4S model airplane lithium battery (4S battery needs less than 16V). 3. 30-35Ah capacity type 18650 battery pack. 4. Battery discharge current <900A, short-circuit current <1800A, outside this range the control board may be damaged. 5. Low capacity 18650 battery and DC power supply cannot be used as power sources; it must have a high-rate lithium battery or car starting battery discharge capacity > 100A!
