More features

• 【Fast Start-Up & Wide Voltage Support】 Supports 100–240 V AC input. After plugging in, the internal capacitor charges in a few minutes and the display shows when the welder is ready, helping you keep an efficient workflow whether in a home workshop or small production line.
• 【Farad Capacitor for Stable High Power Welding】 Built-in energy-storage capacitors deliver a controlled pulse output for consistent weld spots. Maximum pulse welding power up to 10.5 kW (up to 2000 A at 6 V) provides strong, stable welding performance for battery pack assembly. For best results, operate the welder while it remains connected to wall power.
• 【Automatic & Foot Pedal Welding Modes】 Offers two practical welding methods. In Automatic Mode, the welder triggers when the welding pen contacts the workpiece. In Foot Pedal Mode, you position the pen first and then step on the pedal to fire the weld, allowing steadier control on precise welds. Simple operation suitable for both beginners and experienced users.
• 【For Battery Packs & Multiple Metals】 Designed for assembling battery packs such as 18650, 14500, 21700, LiFePO4 and similar cells. Capable of spot welding thin sheets of copper (up to 0.15 mm), pure nickel (up to 0.25 mm), and steel / iron / nickel-plated sheet (up to 0.4 mm), when using appropriate power settings. Always wear protective gear such as safety goggles during operation.
• 【Aluminum Alloy Housing & Complete Kit】 Rugged aluminum-alloy enclosure with smooth edges is resistant to wear and helps dissipate heat. The insulated welding pens include replaceable copper tips for reliable current delivery. Package includes: SK-10P spot welder unit, AC power cord, foot pedal, pair of welding pens, nickel strip roll, battery holders, nickel-plated plates, spare welding tips, fine-grit file and user manual—everything you need to start building battery packs.
