For PLA us the setting is 45 ° which works very well, but for the ABS, you have to be 90 ° while it is default to 80 °
For ABS I have found it matters what you are using as your print surface has a lot of bearing... If you are using the MAXX Perfect Print Surfaces (stickers) then you should get good adhesion at 80 degrees C but I do know a lot of people that believe in that high temperature like Solutions-Concept suggested... If you are using other materials as your print surface there can be varying temperatures that will work based on how they allow the heat to transfer.
