Product Introduction
The SWM-20 portable spot welding machine is a powerful, lightweight, and portable tool that utilizes Dual-Pulse welding technology to create stable, clean, and high-quality joints. In addition to professional welding performance, this device is equipped with a 5000mAh power bank to charge USB devices when needed.
The 2.4-inch color TFT display shows real-time information such as voltage, device temperature, and welding parameters, while the rotary encoder knob allows quick and precise parameter adjustments. These features make the SWM-20 a suitable choice for professional users and DIY project enthusiasts.
Features
Powerful 1200 Amp Output
With a maximum current of 1200 amps, it enables strong, uniform, and reliable welds on various metals.
Dual-Pulse Welding Technology
First pulse: removes the oxide layer on the metal surface
Second pulse: creates a clean, strong, and stable weld
This technology improves joint quality and reduces the chance of sparks or sheet burning.
Compatible with Various Metals (0.1 to 0.5 mm)
Capable of welding:
Nickel-plated steel up to 0.4 mm thickness
Steel up to 0.5 mm thickness
Pure nickel up to 0.25 mm thickness
Iron up to 0.3 mm thickness
Copper and nickel-plated copper up to 0.1 mm thickness
Over 10,000 Fine Adjustment Levels
Allows very precise output power adjustment according to metal type and thickness for optimal weld quality.
