• Package Contents
• This spot welding machine circuit board can be used to weld 18650 / 26650 / 32650 and other lithium batteries . Portable, stable, reliable, and durable — connect it to your own car startup battery or high-power battery pack and start welding immediately. Save on production costs!
• Equipped with an intelligent spot welding program that automatically controls the welding action — no trigger switch needed. Simply touch the welding pen to the nickel sheet and the spot welding pulse is automatically output. Free your hands and weld effortlessly!
• Upgraded from 3 gears to 5 gears , allowing better adaptation to different battery types, lower-performance batteries, and varying nickel sheet thicknesses. More options, more flexibility.
• Improved board structure with a more rational circuit design for enhanced reliability and performance.
• Note: Ensure your battery can supply more than 90A, otherwise welding may fail. If unsure, extend the wire by ~1 meter using 2.5² or 4² wire to reduce the risk of power tube burnout.
