12/11/20 was bought the spot welder and the seller sent it on 14/11/20 and arrived on 15/1/21. I solder the speaker and cut the heatshrink into 4 pieces. I used 8 pieces of heatshrink because the one in the package was not enough, so I used some of mine. The welder has a button which every time you press it increases the spotting Amperes. Last photo is a sample of the 4 brown spots on a used battery on the 2nd scale. It was already spotted so I tried a little bit.
Excellent and Reliable Seller, Highly Recommended. Shipping, 58 days to Greece, the Packets it's OK and Everything is fine. I Test it a little and Working OK, but i think its not make a very strong Welding, but i try again... Thank you very much.
