Do you have gas appliances?
Without the specs on the lift and welder, it is only a guess to what size service you need to the shop.
The shop is 30 x 40 foot.Yes I have gas appliances: fireplace, oven top, tankless water heater.
Specs on the 2 post car lift is: 220Vac, 60hz 1 phase
Small a/c window unit: 115 60hz 1 phase
Welder will be a small unit plugged into 120v
Shop is 100 foot from the home 200amp service
(small power tools with occasion use of a table saw)
Nothing will be run at the same time.
