Portable Digital Color Display Spots Welding Machine Dual Pulse Adjustable Spotwelder 180° Rotatable Display Built-in High Power Relay with Automatic Shutdown Function

Double pulse adjustable spotwelder with high power relay as the core component, the instantaneous current can reach 1500A-2000A, which ensures solid and reliable welding results without the risk of tube bursting, and dramatically improves the service lifespan and stability. The significant advantages of this spotwelder in terms of ease of operation, material quality, intelligent features, and power source compatibility make it a perfect choice for both professional and amateur welders.

Features:
【High Power Relay】: By adopting a high-power relay as the core component, the instantaneous current can reach 1500A-2000A. This ensures solid and reliable welding results, eliminates the risk of tube bursting, and dramatically improves service lifespan and stability.
【Dual Pulse Adjustable Function】: Dual pulse design, providing the pulse adjustable option, users can flexibly adjust the pulse duration and interval according to the specific welding needs to achieve precise welding, applicable to different thicknesses of nickel sheet to ensure welding strength and consistency.
【Premium Material and Humanized Design】: It is made of premium metal and PC material for wear resistance and long durability. Equipped with a large color screen and a rotary encoder for intuitive and easy operation. It also supports a 180° screen rotation angle, which is easy to adjust to meet the needs of different jobs.
【Intelligent and Safety Features】: Equipped with an automatic shutdown function, you can customize the shutdown time from 5 to 60 minutes to save energy. It supports switching between Chinese and English interfaces to adapt to the reading habits of different user groups. It also has a built-in buzzer reminder function, which you can choose to turn on or off according to your needs.
【High Compatibility & Wide Applications】: It supports a variety of powersupply types, including supercapacitors, leadacid batteries, and power lithium batteries. Users can choose flexibly according to the actual conditions, ensuring that the device can operate efficiently in different scenarios. It can easily handle multiple scenarios, suitable for the welding process of cylindrical batteries, spots welding of mobilephone batteries, button batteries, and manual DIY.

How to choose the powersupply?
① Supercapacitor/Faradcapacitor: The individual capacitor should have an internal resistance requirement of less than 0.3 milliohms. It can be powered by 2 strings of 2.7V 3000F in series of 5.4V supercapacitors or powered by 3 strings of supercapacitors. The output current is approximately 1800A when 3 strings of capacitor voltage are at 8.2V. Using 3 or 4 strings of supercapacitor powersupply would be more appropriate.
② 12 V Leadacid Batteries: You can use a 12 V 20Ah-120Ah battery for powersupply. The higher the output current, the higher the capacity of the battery is, and the higher the capacity of the output current is also greater!
③Power Lithium Batteries/Aviation Model Batteries: You can use 2 series of 7.4V-3 series of 11.1V high-rate lithium batteries for powersupply. The internal resistance of a single battery is preferably below 1Ω, and the capacity of 12 V 3300 mAh-12 V 8000 mAh batteries is more appropriate.

Note: The positive and negative poles of the input terminals can not be connected in reverse. Otherwise it will damage the circuit.
