Saldatrice a punti Fnirsi SWM-10 portatile 2-in-1

FNIRSI SWM-10 is a compact portable 2-in-1 spot welding machine with an integrated 5000 mAh lithium battery and powerbank function. It supports dual-pulse technology and can deliver up to 1200 A of welding current. The unit features a 1.8" TFT color display for monitoring voltage, temperature, pulse time and count of seals, and offers wide material compatibility for tasks such as battery tab welding, phone repairs and light sheet joining.

Advantages

Dual-pulse operation improves weld quality by using a first pulse to clean oxide layers and a second pulse to form the joint, reducing sparking and producing more reliable seals. The built-in Class A battery with 5000 mAh capacity supplies high current for extended work and also powers external devices via a 5V/2.1A USB output. A compact form factor and clear TFT screen simplify setup and control, while multiple protections (temperature sensor, short-circuit, overcharge, overheating, overload and undervoltage protection) enhance safe operation.

Suitable for

• Battery tab welding for phones, powerbanks and cylindrical cells
• Spot repairs and small sheet metal joins (nickel, steel, stainless steel, aluminum)
• Field service and workshop use requiring a portable spot welder with powerbank capability

How to use

Charge the internal battery with the supplied USB cable before first use. Select the appropriate power stage and pulse settings on the 1.8" TFT screen according to the material and thickness to be welded. Position the electrodes and the workpieces (battery tabs or metal strips) securely, then trigger the weld cycle. Monitor status information on the display and repeat sealing as required. Use the USB output to power external devices when needed.

Recommendations

For best results, start with lower power settings and a test weld on scrap material to confirm parameters. Ensure clean contact surfaces and correct electrode positioning. Allow short pauses between successive welds to avoid overheating and follow safety precautions provided in the manual.
