Thanks Guys and/or girls,
Makes sense the breakers are protecting the circuit wiring not the not the equipment. It 's when they said to use a 50 amp breaker and 12 gauge wire it sounded like they recommended wiring the breaker to the receptacle [house wiring] with #12
No sub panel, the other one in the pic is the transfer switch box. After four or five years of running extension cords from the generator to the house every time we lost power , happens about 10-15 times a year and last a few hours to a week or so, I installed the transfer switch to connect the generator to some of the more important house circuits , like the fridge and the TV on monday night football days, and be sure to not back feed the service line.

I got the cylinder of mig gas and hope to start to learn how to weld this weekend, if the forecasted snow storm doesn't take place.
