I am someone who has great arms.. by far the strongest and muscle in my body.. and I would not advise on going to failure on every single exercise.
If you go to failure on every set, you are really burning out that muscle.. just like any other body muscle you would train.
What you can do instead is:-
1. Go to failure on maybe 1-2 out of 4 exercises
2. Try supersets
2. Work with positives and negatives
3. Finish off a set with half reps
4. Let your last exercise be something like 21's
