Frequently Asked Questions

Q: What materials can this 10000W portable spot welder handle?

A: This spot welder is designed to weld nickel strips up to 0.3mm thick, pure nickel up to 0.15mm thick, and copper sheets up to 0.1mm thick — making it well suited for DIY 18650 battery pack assembly and similar electronics fabrication projects.

Q: What is the difference between Auto Mode and Manual Mode on this spot welder?

A: In Auto Mode, the machine automatically triggers a weld the moment the electrodes make contact with the workpiece, enabling fast and continuous welding. In Manual Mode, welding is triggered by pressing the included foot pedal, giving you precise, hands-free control — ideal for detailed or intricate battery assembly work.

Q: Does this spot welder need to be plugged into a wall outlet during use?

A: No — the TK-20P is powered by two internal 5000mAh batteries (10000mAh total), allowing it to operate without a direct wall connection during welding. The batteries are recharged via the included USB-C cable, making this a truly portable spot welding solution.

Q: Is this spot welder safe for home or workshop use?

A: Yes. The machine features built-in over-temperature, over-current, and surge protection circuits, plus a flame-retardant V0-rated ABS enclosure. As with any high-power tool, always follow proper safety practices, use PPE, and work in a well-ventilated area.
