The garage is unattached. It has it's own 60 amp subpanel (I tried to

Pity. The next size up would have allowed for a 60 amp welder outlet
plus lighting, etc. As it is, you may wish to install only a 50A
breaker for your welder. If you have a 60A main and a 60A welder, it's
questionable which will trip if the welder pulls a bit much. This could
leave you in the dark.
