Feature:1. For Spot Welder: The intelligent spot welder control board supports spot welding of 0.10.3mm nickel sheets throughout the process, saving time and effort.2. Intelligent Chip: Using intelligent logic control chip to intelligently calculate battery power, the control board has stable performance and safer operation.3. Multiple Functions: Supports the magnification gear, capacity gear, and 6 gear power selection, with low and over power warning function (forbidding welding).4. Current Range: The spot welder control board adopts 6 original MOS tubes, the maximum stable current is 1800A, with 100A900A wide welding current range.5. Welding Mode: The default automatic welding mode, automatic sleep for 8 minutes without operation, the control module is safe to operate, has strong practicability.Specification:Item Type: Spot Welder Control BoardProduct Model: DHJ 02BWorking Voltage: 6.5-16VWorking Current: <20mAStandby Power Consumption: <0.5maRecommended Operating Temperature: -10-60Welding Peak Current: 1800A MaximumSmart Sleep: Automatic sleep after 8 minutes of inactivityWelding Mode: Default automatic welding modeWelded Nickel Sheet Thickness: 0.1-0.25mm (related to battery discharge energy)Common Power Supply: High rate lithium battery, high rate lithium iron phosphate and other lithium batteriesMore Working Power: 1. 12V 30-65Ah battery has good performance and small internal resistance (internal resistance is less than 10 milliohms)m, the discharge current is greater than 100A).

After powering on, the default power on indicator light is on. At this time, welding cannot be performed. It is necessary to select functions such as capacity, magnification and gear at the same time, and then the welding output can be normal.2. Find the brocade, place the brocade on the positive and negative poles of the battery to be welded, the 2 welding pen tips are as close as possible, touch the brocade lightly, and automatically output instantaneous pulse welding brocade after 0.5 seconds; the buzzer beeps after each output After the device beeps, the spot welding pen needs to be removed, otherwise the second output cannot be performed (the purpose is to prevent the battery from being damaged due to too long welding time).3. When the low power indicator is on, it means that the battery power is too low, and the welding effect may not be very good.
