KKMoon 5000 W and Minispotwelder compared. Spotwelding 0.10 0.15 and 0.20 mm pure Nickel strip. 

That is true.

Hmm. Good question! I don’t know! Maybe if you disconnect the foot switch it automatically goes in automatic mode? Gerard

You just keep your foot pressed on the foot pedal and then weld battery after battery. There is a 1.5 second delay after both probes touch nickel. Then you move onto the next battery with your foot still engaging the foot pedal.

At the end of my later video on the KKMoon I mention three more professional spot welders. See ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-qf4BtMmxoaE.html. Greetings, Gerard

Good question! Fact is that things change fast and I did not check comparable products the last two months. I did a check right now but did not discover a very promissing welder. Gerard

I just used it a few times since the video. It seems that the welder performs correctly after fully recharging it.

See my later video on improving the Kkmoon welder. Gerard

Keep your foot pressed down on the foot pedal and don't lift it. While foot is engaging the foot pedal do your welds. Light on device will flash once both probs make contact on nickel and 1.5 seconds later it will weld. After weld go onto next weld but don't lift foot off the foot pedal after the previous weld.

Thanks @@Zer0phobia. I am going to short the pedal connection since my work area is tall and the pedal is barely long enough, and I'll use the welder without the pedal!
