Flux core wire use reverse polarity. Switch the wire inside the cabinet for gas shielded welding solid wire. Use 75/25 carbon dioxide.
110v Mig welding is for clean metal only not anything of high importance for strength.

7018 3/32 is a nice rod to burn but could be difficult to beginners to go uphill.
Buy your machine from a local weld shop they will show you the basics free on your new machine.
If you were local to me you could sit in my weekly class I have at the shop
