About this item:

【Super Capacitor Spot Welder】Super capacitor energy storage battery spot welder is mainly used for spot welding 18650 batteries. It adopts the latest microcomputer control board to accurately control the current and discharge time. Dual mode use, more stable performance, safer. Adopt aviation aluminum alloy shell, high hardness, good wear resistance, anti-crushing, practical.

【Advanced Safety & Intelligent Technology】Built-in power balancing circuit to ensure that the voltage of the two batteries is equal and protect the use of capacitors. Adopting intelligent fan temperature control strategy, when the voltage is fully loaded, the over-temperature protect will be automatically turned on when the temperature is greater than 45 ℃, the fan will stop rotating, the bearing life will be extended, and the buzzer alarm will sound.

【0.1-0.3mm Micro Welding】Dual battery spot welder is equipped with two super capacitors, up to 3000 Farad capacitors, maximum output 2100A, 250 gears adjustable, with LCD color display. It can be used to weld actual nickel strip thickness up to 0.25mm, maximum welding up to 0.3mm, pure nickel sheet within 0.25mm.

【1-250 Level Adjustable】Our spot welder equipment has 250 gears of adjustable output power, which can be easily adjusted by rotating the button (1-25.0 range). Unlike other spot welders, our accuracy is accurate to 0.1 digit. You can adjust the spot welding accuracy according to different needs. The more accurate the adjustment, the more perfect the spot welding effect.

【Dual Mode】Upgraded from the traditional spot welding machine, this spot welder is equipped with automatic mode and foot-operated spot welding plate, which can automatically sense the contact between the welding needle and the nickel strip and automatically output pulses. You can also connect a foot switch to use the spot welding machine according to your habits. Dual super capacitor design, can be used for spot welding of batteries, hardware and electronic components, and is an ideal choice for making battery packs and engineering repairs.

Product Description:

This product is a super capacitor energy storage type spot welding machine. It is mainly used for spot welding 18650 and other batteries. The practical thickness of the nickel strip can reach 0.25mm, and the maximum welding thickness is 0.3mm. Its powerful welding capability allows it to weld 0.1mm thin copper sheets at the total output terminals of the battery pack, thereby increasing its overcurrent capacity.

Product Introduction:

1: The peak data of the dual-pulse welding current can be read to monitor the magnitude of each output current.

2: It can automatically sense when the welding needle comes into contact with the nickel strip and automatically output pulses. It can also be connected to a foot switch.

3: An internal high-power equalization circuit is built-in to ensure that the voltages of the two batteries are equal, protecting the capacitors.

4: The intelligent fan temperature control strategy ensures that the fan stops rotating when the voltage is fully charged, prolonging the lifespan of the bearings.

5: It is powered by 12V DC, which is safer than direct input of 220V and has no risk of electric shock. It can be used in mobile settings.

6: There are 250 fine adjustment settings. The fast/slow knobs can quickly adjust the gear position with different precision.

Notes for Attention:

1: Safety

This capacitor spot welding machine is equipped with both a single-chip microcontroller control system and a hardware balancing circuit. Based on our mature control technology, the super capacitor with a 5.6V withstand voltage can operate stably at 5.0V for a long time, leaving sufficient margin to avoid overvoltage. The 10MOs tube array is controlled for discharge. Each output can be seen on the LCD screen. Before leaving the factory, the welding machine must undergo multiple processes such as welding, calibration, and short-circuit testing to ensure that it can be used directly without adjustment.

2: High Performance

The characteristic of supercapacitors is extremely low internal resistance. By combining a meticulously designed structure and dual pulses, it can achieve an incredibly high performance. The 35-pin configuration can weld 0.3mm nickel strips, and can only use medium settings to assemble industrial-grade battery packs for 0.25mm nickel-plated steel strips and 0.2mm pure nickel strips. It is reassuring. (The 2100A current is measured using an oscilloscope in conjunction with an ammeter probe, and there is no doubt.)

3: Operability

Thanks to the structure of the energy storage welding machine, the built-in high-performance American Microchip single-chip microcomputer can adjust the output current in 250 power levels. The knob rotates quickly/slowly corresponding to different step levels of 1/0.1 milliseconds, enhancing the customer experience to the level of the output. Moreover, it is equipped with two settings: automatic trigger and foot switch, which can be suitable for DIY and batch assembly scenarios.

4: Service Life and Maintenance of Wearable Parts

The core component of the energy storage spot welding machine is the super capacitor, which is a long-lasting component capable of undergoing several dozen cycles. The only wear-prone part is the welding needle. By adding two additional alumina-copper welding needles, it can handle the welding of nickel strips thinner than 0.25mm. Due to the powerful performance of the welding machine, using an excessively large gear position may cause the front end of the welding pen to melt slightly, which is commonly known as "sticking the needle" in the industry and leads to wear. High-end users can purchase high-performance tungsten welding needles by themselves, with a 3.0mm diameter that can be replaced.
