Feature:1. Small and portable, small in size, easy to carry and use to protect the circuit from being burnt out.2. The operation is simple. After turning on the machine, select the required gear and touch the welding object with the welding pen to spot welding.3. Rugged and durable, it is made of aluminum alloy, with hard appearance, long service life, and not easy to be damaged.4. Long battery life, builtin 5000mAH battery, easy to use, can be used for a long time.5. Continuous use of the soldering pen will cause hotness. It is recommended to wear gloves to avoid burns.Specification:Item Type: Spot WelderMaterial: Aluminum AlloyPower Supply Type: Lithium battery (rechargeable)Model: 5VBattery Capacity: 5000mAHOutput Voltage: 4.2v MaximumOutput Current: Maximum 500ADesign Current: Maximum 1000AInput Parameters: 5V/2.1ACharging Voltage: 4.5~5.5V (current 2.5A)Application: Metal weldingSupport Welding: 0.1-0.2 nickel sheet, iron sheet, stainless steelWelding time: several milliseconds.Package List:1 x Host 2 x Soldering Pen1 x TYPE-C Charging Cable1 x Manual Note:1. Please fix the spot welding items in the spot welding mode;2. Please keep the welding objects in a flat state;3. Keep cooling time about 10S after weldingPrecautions:It can be operated while charging and discharging, and it will enter standby mode when chargingIt is recommended to charge the battery once half a year when it is not used for a long time, and the charge is 75% Continuous use of the soldering pen will cause the appearance of hot, it is recommended to wear gloves to operateDo not drop, flood, heat, etc. which are harmful to electronicsThe blackening of the tip of the soldering pen will affect the effect, which can be worn off with sandpaperIf the spot welding is too long or the shutdown is caused by good contact, just restart it
