Thank you my friend i am going to buy now

why do you weld on the same spot as before ? on each power level you have to weld on different spots to see how good is the welding

Yes correct, I thought it was clear to see the differences, I didn't weld in the same place, I will make a new video in a few days sawing only that.

I can't seem to weld 2mm nickel it just don't hold with this spot welder anyone got any tips on how to do it thanks

Bought this unit and it doesn't seem to have enough power. Put it on the highest level and still nothing. Going to return.

Where’s the link for this ??

What is the principle of welding batteries? I understand the basics and that the welding spot should have the highest temperature for the shortest time. We have a spotter with a bunch of settings: first welding, second and third, where the second welding is the main welding and the third is hardening. There are also peripheral settings such as pause between pulses, current rise and fall times. So let's get down to business: the first and last welds should not have as high a current as the second. The first weld prepares the nickel strip for welding, the second welds it directly, and the third releases the strip. We have two main problems that I still can't figure out: 1. Why do the electrodes "stick" to the workpiece? According to my observations, this is due to the cross-sectional area of the electrode tip in contact with the nickel tape. On the one hand, a smaller contact area creates better welding, but the electrodes stick 👉👈 On the other hand, a larger area cooks worse. By increasing the current, the workpiece overheated too much and still nothing happened) 2. One electrode cooks and the other does not. In the case of DC welding, this is understandable. The "positive" electrode, where the current enters the battery substrate, welds better than the "negative" electrode, where the current leaves the battery. However, with AC welding, this is illogical for me, because the current flows back and forth across the workpiece. Maybe someone has a few gigabytes of information about welding batteries?) I want to absorb all the text from anyone that is related to welding batteries
