Spot Welding Pen, Mini Spot Welder, Automatic Trigger, Integrated Spot Welding Pen, Spot Welding Equipment for Industry (Black)

Eccentric Welding Needles: By using eccentric welding needles, it is possible to weld very narrow sheets, and at the same time, the two welding pins are held perpendicular to the sheet, which increases the current.The spot welding pen comes standard with a pair of concentric ball needles, which work well.Thick Brass Rod: This battery-powered spot welding pen is made of a thick brass rod, which has a higher current capacity, no heat resistance, and more stable spot welding power.It is suitable for extended use and improves efficiency.One-Hand Operation: With a built-in stroke switch, it can be operated with one hand.You won't get tired due to long strokes and heavy spot welding handles during extended use.It is very suitable for mass production.Easy to use: It won't happen that an ordinary integrated spot welding pen fails to achieve pressure balance between the two welding pins, resulting in a weak weld and sparks.Double springs: There are double springs in the handle that can be retracted; each welding pen retracts independently, and the force is moderately controlled.
