Things are moving on well, tested about 600 cells so far :Smile
Im doing a practice run for the soldering and something doesnt seem right. If you look at the picture you can see the solder is just a ball sitting on the cell and its like brown around it. its not a flat blob like from other people. The one column, third from the right is a different solder (the small roll) and that one looks better.
I have an 80W soldering iron, reaches about 490°C according to the manual. Too hot?
What am I doing wrong? Please help. Thanks!
I didn’t find the right solution from the Internet.
