Advice: #4 copper with a 90 amp breaker? electricians

What's your take on this? I'm installing a sub panel that's rated at 75C. Will this breaker protect the wires or should I downsize to an 80 amp breaker? This sub panel will supply power to a small workshop, which at most will have a 50 amp welder on or a shop vaccum and a table saw on at the same time. With a refrigerator ~4.5A and lights on at all times. (I'm in Los Angeles, CA)
