Awgem AS1 Portable Spot Welder Handheld Battery Welder Support Replaceable Pin Adjustable Spacing, AS1

1. Engineered with dual-pulse welding technology that delivers a pre-heat deoxygenation pulse followed by a main welding pulse. This ensures stronger, cleaner, and more consistent weld joints. With 11 precise gear levels shown on the circular LED indicator lights, you can easily select the output power to suit various nickel sheet thicknesses.
2. Unlike traditional spot welders with bulky external cables, this pen-style welder features an innovative 2-in-1 integrated body. Crafted from premium aluminum alloy with an ergonomic curved profile, it weighs only about 160g (0.35 lbs), making it lightweight, non-slip, and extremely comfortable for one-handed operation.
3. Features a scientific embedded replaceable needle design using movable guide rail and fixed technology. Say goodbye to traditional threaded welding needles that easily loosen and cause dangerous sparking. The dual-pin spacing can be flexibly adjusted to align properly with different battery layouts and prevent accidental short circuits.
4. Equipped with a brand new, highly efficient safety lithium battery cell featuring ultra-low static power consumption (80 uA). On a full charge, it delivers up to 1500 continuous spot welds, completely eliminating battery anxiety during daily DIY projects. Built-in 8-minute auto shutdown preserves power when left idle.
5. The kit comes fully packed with 1 AS1 spot welder, a 0.5m charging cable, a 2m nickel strip roll, 1 piece of sandpaper for pin cleaning, and 1 pair of spare copper welding needles. Built with multi-layer hardware and software safety protections against short circuit, over-temperature (-10C to 60C protect range), overcharge, and impact.
