4.2V Handheld Spot Welder Automatic Welding Tools

Features:

The welding machine itself has overcurrent protection, low voltage protection, overvoltage protection, and overtemperature protection.

Lithium battery protection: charging to 4.2V can prevent battery expansion.

When in the off state, thanks to the low power consumption feature, it can be standby for up to one year.

Two ultra-high rate model airplane lithium batteries, the discharge peak value can reach 630A+, all high-current circuit layouts, use infrared thermal Imaging to optimize the design, and better share the discharge current.

Short-circuit protection of the soldering pen.
