Anyway, I found that I don't have 220v at home. I finally brought it back (220v with gas option) and exchange for a 110v without gas option (I want the gas option but there is no such 110v with gas option). Then, I finally have some time to try some welding today. At the end of the day, I was so happy that I could actually "connect 2 pieces of metal together" but I created an ugliest weld ever seen, and there were so many of those bibi rounded balls scater and sticking around the welded area
. I think maybe because the metal is too thick, will try something thinner tomorrow.
Is 2mm too thick for 110v MIG100? It said 90 amp max.
