USA DIY Portable Mini Spot Welder Machine Welding Power W/ Pen for 18650 Battery
Product Description
Product Function:
The welding machine precisely controls the output current of the MOS tube through the single-chip microcomputer. A high temperature of more than 2000 degrees is generated at the welding point to make the nickel sheet welded firmly. The welding machine itself has functions such as over-current protection, low-voltage protection, over-voltage protection, and over-temperature protection. Intelligent output current. It can be used safely, even if the soldering pen is short-circuited, it will not be damaged.
Specification:
● Brand new
● Material: hard aluminum alloy
● Cell: 2 * High-speed cell (included)
● Output Voltage: 4.2V max.
● Output Current: 700A max.
● Color: black shell, brass soldering pen
● Size: approx. 105*83.2*28.8mm
● Independent battery indicator light, mode light
● Pulse time: 9 levels adjustable (key cycle)
● Trigger delay: 0.5 seconds
● Adaptation charger requirements: 5V 2A
● Features: automatic trigger, detachable soldering pen, TYPE-C charging, short circuit protection
● Design: Sturdy appearance, light splash resistance, firm connection, dispersion brazing pen, life span of 50,000 cycles.
Key parameters of the welder: 0.1 smm nickel strip welding force, steel shell 18650 battery assembly. For large monomers, the aluminum electrode must be welded after turning to nickel, and welding is about 800 points. Support welding while charging, theoretically unlimited battery life , battery capacity is about 5AH
Product Features:
1. Lithium battery protection
The existing second-generation products use a charging method of 4.2V instead of 4.25V. While preventing full charge, it avoids the trouble of recharging and waiting for each use.
2. Low voltage protection
The working voltage platform of the power file battery is narrower than that of the ordinary Keng battery. This welder adopts the strategy of less than 3.2v protection, leaving space for low pressure and guaranteeing safety.
3. Low power consumption function
Long press to turn on/off, short press to cycle through 5 gears, all operations can be performed quickly and concisely. When in the off state, thanks to the low power consumption feature, it can be standby for up to one year.
4. Thermal optimization
This product uses 2 ultra-high-rate model airplane batteries, the discharge peak can reach 630A + all high-current wiring, and the infrared thermal imaging is used to optimize the design to better share the discharge current.
Unique secret: short-circuit protection of the soldering pen
Principle: As shown in the figure, a high-speed protection system is built in the microcontroller. When the welding current is too large, the ultra-high-speed comparator will instantly turn off the output as shown by the red arrow to achieve the purpose of protecting the welding machine.
Under normal circumstances, this function module will not trigger
Once the protection is triggered, lift the pen to automatically release the protection
Use Instructions:
1. Please extend pressing for 3 seconds. When the buzzer rings, that is turn on/off.
2. Short press the button. If the buzzer rings, that is shift position. Press one time, and it can add 1 gear. 1-9 cycles, and the 9th gear is the strongest welding strength.
3. After placing the welding pen, the buzzer rings. Waiting for about 0.5 seconds to trigger welding.
4. When charging, the power indicator flashes. When all 4 lights are on to indicate that it is fully charged. Welding can be performed while charging.
