1. Dual Pulse Control 2025 mini spot welder uses dual pulse precision technology with 99 adjustable settings, easily switching between single click precision and continuous welding. Delivers more than 1,000 welds per charge for marathon productivity. Two way port charging can power the tool while charging other devices. What this means for you: Flexible control for delicate, precise welds or faster, continuous welding. Longer operation between charges and convenient charging for other devices. 2. Auto Guardian Mode Upgraded chipset continuously monitors temperature and current. Automatic shutdown occurs at 140 F / 60 C, with real time voltage adjustment. Intuitive interface provides performance feedback to help beginners and professionals achieve reliable results. What this means for you: Safer operation with automatic protection. Real time adjustments help you dial in weld quality quickly. 3. Full Color LCD Display 1.9 inch full color display for control and diagnostics. Real time data includes temperature and power monitoring, welding parameters, battery health analysis, and status alerts. Quick adjustment via a tactile interface for fast workshop changes. What this means for you: Clear, at a glance information to fine tune settings. Easy monitoring of tool health and weld conditions during projects. 4. Replaceable Brass Welding Head Welding head is precision designed with aviation grade brass for conductivity and industrial durability. Modular design enables instant head replacement, maintaining performance across 10,000 welding cycles. What this means for you: Long head life and straightforward maintenance. Easy head changes to suit different tasks without downtime. 2 3 practical use scenarios Battery pack assembly and : welding nickel or copper tabs on Li ion or Li polymer cells for small to mid sized battery packs used in drones, RC vehicles, or portable devices. Electronics and metal fabrication: spot welding thin copper or aluminum sheets, foils, or tab connections in compact electronics enclosures and prototypes. Hobby and small scale production: rapid, repeatable welds for custom projects, quick repairs, or small batch fabrications where consistent weld quality is required.
