The SWM-20 portable handheld welding machine is an efficient, practical, and highly mobile welding tool designed for precision. Its advanced dual-pulse technology ensures exceptionally stable and robust welds every time. Beyond welding, it also functions as a versatile power bank for your devices. The integrated 2.4-inch HD display provides a clear, intuitive user interface, while the precision encoder knob allows for effortless and accurate parameter adjustments, significantly enhancing the overall user experience.
1. Advanced Dual-Pulse Technology for Industrial-Grade Welds
Equipped with a powerful 1200A maximum output and advanced dual-pulse welding technology, this tool ensures cleaner, stronger, and more consistent welds. The preheating and main pulse phases work together to eliminate sparks and oxidation, making it perfect for building massive 18650/21700 battery packs with professional-grade stability.
2. 2.4" HD Color Display & Precise Encoder Tuning
The vibrant 2.4-inch high-definition screen provides a crystal-clear, real-time view of your parameters, including preheat time, interval, and pulse width. Combined with a tactile encoder dial, you can adjust settings with surgical precision, resulting in a significantly smoother and more intuitive experience than traditional button-only models.
3. Professional 0.5 mm Welding Range & Customizable Gears
The SWM-20 effortlessly welds nickel, iron, and stainless steel sheets with thicknesses from 0.1 mm to 0.5 mm. With four combination gear modes and adjustable continuous spot welding (1-9 spots), you can perfectly tailor the heat output to the thickness of your specific project materials.
4. 2-in-1 Versatility: Spot Welding & 5000mAh Power Bank
The SWM-20 features a high-performance lithium battery with 5000 mAh battery that supports 5V/2.1A fast charging and discharging. It's not only a top-of-the-line welding machine, but also serves as a reliable portable power bank for charging smartphones or tablets during outdoor repairs or emergencies.
5. Compact, Portable, and Safety-Oriented Design
Designed for DIY enthusiasts and professional technicians alike, this handheld welding machine is compact enough to fit in your pocket or toolbox. The ergonomic design ensures a comfortable grip during extended use, while the integrated safety management system prevents overheating, making it the ideal on-the-go solution for battery pack maintenance and lab experiments.
