Most beginners burn through a cell on their first try. It almost always comes down to the power setting and dwell time.

Steps
1
Power settings map to discharge energy. Low for 0.1mm strip, medium for 0.15mm, high only for 0.2mm.
2
Probe spacing: 3-4mm works best. Too close and the current takes a shortcut without heating; too far and the weld will not hold.
3
Test first on a dead cell. On a good weld the strip tears before the joint lets go.
4
Reading the weld: round and bright is correct; dark means too much energy; no mark at all means a cold joint.
5
Safety: wear eye protection and put insulating rings between the terminals to prevent shorts.
焊点发黑就是我的问题，原来是档位太高了。
