Welding questions

I used a Hobart handler 120 [110 v] gas shielded mig welder set at # 2 wire speed and #1 on heat with few burn thru [rusty metal on the back side I did not see], this was the first time I ever had welded anything and I did pretty good as I was told by others whom saw my work. I tried flux core, I suppose it can be done but not by a newbee all I did was burn holes in the metal.
