Frequently Asked Questions
Q: What materials can the TK-20P spot welder weld?
A: The TK-20P dual-pulse spot welder is capable of welding pure nickel strip (up to 0.15 mm), nickel-plated strip (up to 0.3 mm), as well as steel, iron, and copper materials — making it highly versatile for battery tab welding and general electronics repair.
Q: How is the TK-20P spot welder charged?
A: The TK-20P charges via its built-in Type-C port (5V/1A). Simply connect the included Type-C charging cable to any compatible USB power source. Its dual 5,000 mAh battery configuration ensures extended working sessions between charges.
Q: What is the difference between Automatic and Manual modes on the TK-20P?
A: In Automatic mode, the welder triggers a pulse as soon as the welding pen makes contact with the workpiece. In Manual (foot pedal) mode, the foot pedal controls the firing — ideal for hands-free operation where you need both hands to position the workpiece or hold components steady for precision welding.
Q: Is the TK-20P suitable for beginners?
A: Yes. The colour TFT LCD display, clear parameter readouts, and 18 adjustable power levels make it straightforward to set up. The included sandpaper, nickel plate, spare needles, and welding pens mean beginners have everything needed to start welding right out of the box. Always follow appropriate workshop safety practices when operating high-current equipment.
