Specifications: Certification: None Origin: Mainland China Model Number: Spot Welding Machine Max. Welding Thickness: 0.1mm Dimensions: 170 x 25mm Weight: 150g Usage: Spot welding Wire Length: 350mm Wire Specification: 12AWG silicone wire Power Interface: Copper lug / EC5 (optional) Operating Voltage: 12V-16.8V Spot Welding Current: 80A-150A Power Module: Imported 550A MOS tube Case Material: High temperature resistant nylon Spot Welding Material: 0.1mm nickel-plated tape Welding Needle Specification: 3 x 1.5 x 40mm professional alumina copper welding needle Copper Needle Replaceable: Yes Material: ABS + metal Package Included: 1 x Welding Machine Needle (Choose interface option) Key Points of Use: We recommend a 12V, 20AH-60AH lead-acid battery, or a high-rate 3-string or 4-string lithium battery pack as input power (must perform well, enough to start a car; voltage range: 12V-16.8V). Ensure firm connections and avoid extending wires randomly. Start with low power for spot welding and gradually increase to avoid excessive current impacting MOS tube performance. Do not reverse-connect input electrodes or exceed specified voltage range. For best results, weld 0.1mm nickel-plated steel strips. Achieving 0.2mm thickness is possible with double welding. Avoid welding pure nickel, copper, or aluminum. Note: Due to different monitors and lighting, actual item color might slightly vary from the pictures. Please allow a 1-2cm deviation due to manual measurement.
