5V 2A 5-Gear Spot Welder for 0.1–0.12mm Nickel Strip – 18650 Battery Pack Welding Tool

The 5V 2A 5-Gear Spot Welder is a compact handheld welding tool designed for spot welding thin nickel strips onto compatible rechargeable battery cells. It is particularly suitable for battery pack assembly and repair projects involving 18650 lithium-ion cells.

The unit operates from a 5V power input and provides 5 adjustable gear levels, allowing the user to select the appropriate welding level for the application. It is designed for use with nickel strip or nickel sheet in the 0.1–0.12mm thickness range, as specified for this product.

Its compact handheld format makes it convenient for DIY battery pack builders, electronics hobbyists, technicians, and repair users who need a portable spot-welding solution. Spot welding nickel strips helps create electrical connections between battery cells while avoiding the need to directly solder onto the cell terminals.
