The dual-pulse welding method helps make the weld more stable and reliable. The first pulse prepares the contact area, while the main pulse performs the weld. This is especially useful when working with thin nickel strips and battery contacts.

🛡️ Safety Protection

The SWM-10 includes several safety protection functions for more stable and reliable operation:

• over-temperature protection;
• low-voltage protection;
• short-circuit protection;
• intelligent warning reminders on the display.

✅ Advantages

• Portable and lightweight
• No external power supply required during operation
• Suitable for battery pack assembly and repair
• Can also be used as a power bank
• Clear color display
• Adjustable welding output
• Practical for both hobby and workshop use

📦 Recommended For Use With

• 18650, 21700 and similar cylindrical battery cells
• Nickel strips
• Battery holders
• Electronics repair tools
• Insulation rings and battery assembly accessories

Note: always select the correct power setting according to the thickness and material of the welding strip. Excessive power may damage the battery terminal or nickel strip.
