I want to run a dedicated line to garage for 220 volts on 50 amp breaker. This is for a stick welder. What gauge wire do I need? Which wire hooks up where?? Breaker and receptacle. And then I have picture of my breaker box. Will it work with 50 amp breaker on lower left side? Thanks in advance

If it is a detached garage and you have lights and receptacles the feed for that will need to be abandoned and a subpanel installed at the garage. You can only have one feed to a detached structure.

It's an attached garage. All the outlets are fed by this box. I just need to run about 20 feet of wiring from the box to attached garage.

6-2 NM-b on a 50 amp breaker.

(Note the NEC has special rules for welders based on duty rating that might allow smaller cable and/or beaker but going with 6-2/50a breaker is good future proofing.)

I just learned about duty ratings and understand what you're saying... and agree if you're going to go to the trouble to install a new line/outlet...you may as well make it to handle anything down the road. Thanks!! Off to get my wire/breaker/receptacle...
