Automatic DIY Spot Welding Pen Integrated Trigger Handheld Welder Pen for 18650 Battery Packs

Overview

Tired of fumbling with foot pedals while trying to hold battery cells in place? Our Automatic Spot Welding Pen is designed for high-efficiency, professional battery pack assembly. It features an integrated trigger mechanism that detects when the welding needles are pressed against the workpiece. This one-handed operation allows you to use your other hand to stabilize the battery pack, significantly increasing your production speed and safety.

Key Features

• Integrated Automatic Trigger: No external foot switch needed. Simply press the pen down, and it fires once the built-in springs reach the set tension.

• Dual Spring Tensioners: Each welding pin is backed by an independent high-tension spring, ensuring even pressure on both contact points to prevent sparking or weak welds.

• Pure Copper Construction: High-quality, thickened copper bars ensure low resistance and high current throughput (perfect for welding 0.1mm to 0.3mm nickel strips).

• Ergonomic Design: The sleek, handle-shaped body reduces hand fatigue during long assembly sessions.

• Universal Compatibility: Comes with standard ring terminals, making it compatible with most DIY spot welders, DH30 modules, and transformer-based units.

Technical Specifications

Why go Automatic?

• Consistency: Foot pedals often lead to pre-firing before enough pressure is applied. This pen ensures the circuit only closes when the pressure is perfect.

• Safety: Reduces the risk of accidental firing.

• Ease of Use: Frees up your feet and focus, making it easier to line up 18650 cells in tight spacers.
