Okay, so just change it at the printer? Does Cura not set anything concerning temp when the G code is written?
The answer to that question depends on the type of UM printer you have. Please update your user profile to indicate that you have a UM2 and what country you live in as many answers vary depending on the country.
On the UM2, normally, you control the temp in the material settings. However you can also alter them in the UM2 TUNE menu live as you print or using a plugin inside Cura, or by editing the gcode file manually, or by switching to "reprap" gcode style (not recommended). The main way to do it is in material settings.
ABS needs high temperatures for good layer adhesion - if not you will get parts that break easily along layers. It helps immensely to use low fan. Or no fan at all. I usually do 30% max fan and only for bridging or overhangs. If the part is simple (say a cube, lol) then no fan at all. The fan settings can be tweaked in material settings also so that you can slice a part and not worry if you print in PLA or ABS. But I tend to mess with the fan settings only in Cura.
It's kind of bad to mix PLA and ABS often. ABS needs higher temps which can mess with the isolator more quickly and then when you switch to PLA suddenly you get underextrusion. But if you stick with only ABS you will be fine printing happily at 260C for months. I don't print much ABS so I usually do 245C but that tends to be weaker than normal parts (but plenty strong for most things!). ABS experts I believe tend to print at 250-260C.

Hi harley573
you can changer the materiel settings on the front panel of the UM, click "materiel" then "settings", also here you can define your own settings
good luck
oh and welcome to the forum too
