Auto Mode Operation: Simply touch both pen tips to the nickel strip - the welder fires instantly. The rotary knob allows precise adjustment of 0 - 100 power levels, so you can easily handle both delicate tasks (phone/button battery) and heavier applications (cylindrical battery packs) with optimal results every time.
Note: This unit uses automatic mode (no foot pedal). Turn the knob to "A" before use. We recommend practicing on scrap metal first.
Low Battery Warning & High Safety: The battery level flashes while charging - a full charge takes about 2.5 hours and gives you up to 200 consecutive welds at max power. If something goes wrong (low voltage or overheating), on-screen icons light up and the welder automatically shuts off until conditions return to normal
Set Includes: Includes 1 x 5000 mAh SK1 battery spot welder ( 0.8 lb, 4.0" × 5.3" × 1.8" ), 2 x welding pens, 1 x roll of nickel-plated strip, 1 x Type-C charging cable, and 1 x user manual. It makes a perfect gift for family, friends or DIY battery enthusiasts
