Melting point of mild steel is much lesser as compared to temp of the arc. So, what temp does the metal pieces when they are in molten state. Plz do include the chemical composition of mild steel and scrap iron.

I heard that melt point of the mild steel is around 1200 degree cel and the metal pieces are heated upto 700 deg only during welding process.

First, mild steel refers to a range of steels with a lower carbon content, typically under 0.2 - 0.3 weight percent, depending on who you ask. Scrap iron also has many different compositions, depending on the source.
Back to the first question. If the temperature of the arc is 6000 celsius, then the temperature of the molten region is somewhere below that. Some localized areas near the path of the current may be near 6000 degrees, but the rest just melts, and that's the only concern in the process.

Its a 6011 not a 7011. Get the smallest diameter they have. A 6011 is a fast freeze deep penetrating rod that works good on rusty and painted surfaces. Your best bet it to make a series of spot welds about 1/2" apart , let it cool and then fill inbetween. If you melt a big hole on thin tubing it can be a real pain to fill.

you are able to control the are by the amperage on the welder, it also depends on the thickness of the metal. example
to burn a 7018 electrode size 3/32 you need to have 75 - 100amps,and that will weld two plates of metal together from the size of 3/32 to 1/8 thickness
