Its compact design and powerful performance, this handheld cordless welding machine offers convenience and efficiency for all your spot welding needs.The Portable Spot Welder with LCD Screen and 5000mAh Battery is a must-have tool for DIY enthusiasts and professionals alike. - Specification - Material: ABSBattery: 1 x 5000mAh Rechargeable Lithium Battery (Built in)Charging/Discharge: 5V 2.1AWelding Materials: Ni Sheet, Iron Sheet, Stainless Steel Sheet, Aluminum SheetWelding Thickness: 0.1-0.25mmMaximum Welding Current: 1200A - packing list - 1 × Battery Spot Welder2 × Welding Pens1 × USB Cable4 × Accessories1 × Instruction ManualHow to Use:1. Preheating Pulse: Before spot welding, briefly heat the electrode to achieve the predetermined temperature. (By default, 2ms is optimal.)2. Main Pulse: During spot welding, the equipment will output a brief high energy pulse to generate sufficient welding heat, while avoiding electrode overheating and excessive current to burn through or melt the material. (According to the actual situation, adjust the size of the main pulse. If it is too large, it can be directly welded through, but if it is too small, it cannot be firmly welded.)

• 【PORTABLE SPOT WELDING MACHINE】- The dual pulse spot welding technology ensures stable welding with a weldable thickness of 0.1 to 0.25mm and a maximum welding current of 1200A. It offers 4 combination gear adjustments.
• 【DOUBLE PULSE WELDING TECHNOLOGY】- During welding, two pulses are released. One pulse cleans the oxide layer on the exterior of the workpiece to reduce spark splashing, while the other pulse is used for welding to ensure consistent energy output and effectively improve welding reliability.
• 【ADJUSTABLE HANDHELD CORDLESS WELDER】- With a 1.8-inch color LCD, users can easily monitor internal temperature, charging status, battery level, gear position, and time interval for efficient operation.The welding pen is made of high-temperature wires with good conductivity, torsion resistance, and low contact resistance.the refill of the soldering pen can be replaced.
• 【RECHARGEABLE WELDING MACHINE】- With a built-in 5000mAh rechargeable battery and a C-type charging cable, this spot welder can be fully charged in 3 hours. It can continuously weld thousands of points and even be used as a power bank for mobile phones.
• 【WIDELY USED】- Weldable multiple materials: suitable for thickness 0.1-0.25mm nickel sheet, iron sheet, stainless steel sheet, and 0.1-0.3mm aluminum sheet. and is mainly used for soldering mobile phone batteries, circular battery soldering, power bank repair, and battery assembly, etc.
