Feature:1. Super Performance: This spot welding machine can complete ultra thin to ultra thick welding work. It has a specially designed aluminum to nickel welding selection mode, which is specially used for the use of pure nickel sheets for iron lithium power battery transfer welding.2. Capacitor Energy Storage Type: The welding machine has inverter energy storage type super capacitor discharge technology, which avoids interference with AC power supply. The pulse current can up to 3500A, and the pulse power can output up to 19.8KW.3. Dual Welding Tool: Our welding machine is triggered by dual mode spot welding, which realizes precise spot welding and fast efficiency, which is convenient for users to use a wide range of batteries or metal parts flexibly.4. Digital Display Screen: The spot welding machine is equipped with a digital display screen combined with intelligent program design, with real time display of welding pulse current, which can be monitored to avoid false welding of solder joints.5. Accuracy Welding: The high energy polymer pulse welding technology can realize concentrated and thin solder joints, deep penetration of the molten pool, no blackening of the solder joints, no heating of the welded parts, and no damage to the welded battery.6. Safe Use: The built in safety self discharge device can release the energy of the storage capacitor to 0, and the low loss metal confluence process ensures that the machine does not get hot when used for a long time.Specification:Item Type: Battery Spot WelderMaterial: Aluminum alloyPlug Input Voltage: AC100-240V 50 or 60HZSupply Voltage: DC15VOutput Voltage: 5.2-6VPeak Welding Energy: 238J (joules)Pulse Power: 19.8KW (peak)Trigger Mode: Automatic trigger AT or foot trigger MTAbility Level: 0-99TSpot Welding Mode: Separate moving spot welding penPulse Time: 0-20mSPreload Delay: 100, 200, 300, 400, 500mSFirst Charge Time: 18 minutesBody Size: (L x W x H) Approx. 67 x 176 x 126mm / 2.6 x 6.9 x 5inSpot Welding Thickness Range: 0.05-0.5mmLithium Battery Linked Nickel Sheet Specification:Model: Nickel Aluminum Composite SheetSize: Approx. 0.15 x 10 x 100mm / 0.01 x 0.4 x 3.9inQuantity: 20PCSResistance Value: 2.9m/100mmAllowable Current Value: 30-40AAntioxidant Properties: GoodModel: Pure Nickel SheetSize: Approx. 0.15 x 8 x100mm / 0.01 x 0.3 x 3.9inQuantity: 20PCSResistance Value: 6.9m/100mmAllowable Current Value: 10-15AAntioxidant Properties: Good.Package List:1 x Spot Welder1 x Pedal Switch1 x Power Adapter2 x Split Spot Welding Pen1 x Rocker Arm Down Pressure Welding Tool1 x Rocker Arm1 x Base4 x Rocker Arm Down Pressing Welding Needle2 x Welding Pen Pin1 x Hex Wrench20 x Pure Nickel Sheet20 x Nickel Aluminum Composite Sheet1 x InstructionNote:1) Make sure to select AL or NI mode and the energy storage voltage can up to 6V,2) Confirm that the plug of the spot welding pen has been fully inserted into the pulse interface of the welding machine,3) Confirm that the MT trigger mode is selected for the test,4) Set the pulse width to 2540t,5) Confirm that 0.2mm thick pure nickel or nickelplated sheet is used,6) Confirm that it is welded to a flat aluminum plate without oxidation pollution,7) Apply a stable pressure of 12kg to the nickel sheet (subject to no sparks).
