Sambuddha,
Listing the max. and ranges leads me to believe you know the steel type and grade. It would be easier to suggest an electrode knowing the steel type. Or you are posting the question that your school asked? All your other posts have a similar flavour.

Not bashing you if you are a student, but you need to do some work too. At least research what type of steel it is similar to.

The material is a medium carbon with minor alloy additions. I would approach it as a medium carbon steel, using sufficient preheat and I would use an undermatched low hydrogen filler metal if the joint is highly restrained.
