Portable Spot Welding Pen with Dual Springs for 18650 Battery
Product Description
Thick Brass Rod: This 18650 battery spot welding pen is made of a thick brass rod, which provides higher current capacity, no heat resistance, and more stable spot welding power. Suitable for long-term work, it improves efficiency.
Dual Springs: The handle contains dual springs that can retract. Each welding pen is independently retractable, with moderately controlled force.
Eccentric Welding Needles: By using eccentric welding needles, it is possible to weld very narrow sheets while keeping both welding pins perpendicular to the sheet, which increases contact current. The spot welding pen comes standard with a pair of concentric ball needles, which work well.
One-Hand Operation: Built-in travel switch allows one-hand use. It prevents fatigue caused by long strokes and heavy spot welding handles during extended work. Very suitable for mass production.
Easy to Use: Unlike ordinary integrated spot welding pens that cannot balance the pressure of both welding pins—leading to weak welds and sparks—this design ensures stable and reliable welding.
