H2 type : Big Color Screen and 90 Gears adjustable Features: 2-in-1 spot welding pen- a handheld spot welding machine that does not require additional spot welding pens. It is easy to carry around and go anywhere. It combines the built-in power supply and soldering pen into one, allowing for easy soldering without the need for an external soldering pen. Widely applicable - suitable for cylindrical batteries such as 18650/26650/36650, mobile phone batteries, and electronic devices that require batteries. Spot welding machines can be used for electronic devices that are damaged due to battery damage, replacing batteries and restoring use (similar to handheld drills), saving money and protecting the environment. 90 Adjustable Gears - The spot welding machine is equipped with 90 gears with adjustable output power, which can be adjusted according to the material you spot weld. Charging once can spot weld more than 1500 times. Circular LCD color screen- The spot welding machine has a 1.3-inch LCD display screen. The UI display screen presents functions with a circular dial, making circular shapes easier to distinguish. There is a protective film, which may cause scratches. Please remove the protective film. Better protection - The high-density aluminum alloy shell of the spot welding machine is excellent for heat dissipation. Provide overcharge protection, temperature protection, short circuit protection, and low power consumption indication. In addition, the spot welding machine will automatically shut down for 6 minutes after operation, so you can use it without any worries. Multiple protection measures - it is a mini handheld spot welding machine, but it has high-quality polymer battery, overcharge protection, temperature protection, short circuit protection, abnormal battery temperature alarm and spot welding function shutdown, low battery voltage and ultra-low power consumption, longer standby time, Type-c5v2a port charging (high voltage is strictly prohibited). Exquisite Packaging - Our packaging includes a handheld spot welding machine, 2-meter nickel plated sheet, 1 piece of frosted paper, 1Type-C charging cable, and a manual. Our packaging is very exquisite, making it a very worthwhile gift for your loved ones and friends who love battery DIY.
