Is Smart Device:no Usage:Welding batteries Max. Welding Thickness:0.2mm Rated Capacity:10000mAh Model Number:DH30 MAX Origin:Mainland China Certification:CE,EAC,FCC DH30 MAX Specifications Material: Metal Case Screen: Color Battery Capacity: 10000mAh Welding Output: MAX 650A Charging Port: Type-C Product Weight: 470g Product Size: 150x83x29mm U DIsk Firmware Upgrade Packaging Include 1 x Mini Spot Welder 1 x Welding Pen 1 x Type C Charging Cable 1 x 0.12mm*8mm*2m Nickel Plated Steel Belt 1 x User Manual How to Welding Long click the button more than 3 seconds to power on or off the spot welder Try different spot welding power from low to high,we suggest use gear 11 or 12 to welding 0.12mm Nickel steel strip,if set the MAX gears,Nickel belt will be broken down or spot welder will power off to protection mode,It is not that the higher the power, the better welding effect is. When welding, press down the soldering pin lightly, and the nickel sheet and the battery can be bonded together. The harder you press, the less solid the welding will be. It will automatically trigger after pressing down for one second. How to Charging We suggest directly connect the black charging wire coming with spot welder from power adapter to spot welder，and power adapter need 5V current above 2A. We not suggest use PD charger or connect any other voltage current meter,because some PD charger and wire can not output a 5V voltage,type C to type C connect will have some charging problem! Spot Welder include high discharge lipo battery,for safe delivery,it have low power,inside IC control charging current when battery is low power, In the case of low power, there may be a low voltage alarm and the screen is not bright, continue to charge, the screen will return to normal charging，we suggest charing more than 30 minutes. Precautions for maintenance The spot-welding machine has a built-in high-rate lithium battery, which is different from the mobile phone battery. The high-rate lithium battery can discharge with high current, so if it is not used for a long time, it may cause the battery voltage too low to shut down, and serious may cause battery damage. We recommend charging it to about 80% for storage in 2-3 months
