Disconnect needed for welder outlet?

Iím putting in a 30A 220v circuit for a Hobart 190 welder in a detached garage with an existing sub panel. Seems straightforward using 30A double breaker and running 12/2 to a 50A welder outlet ( nema 6-50r I think?).

The manual show a disconnect with a 30A fuse. Not sure if the breaker at the panel works for this or if I need a close by disconnect and what would be itís purpose? I have an on-off switch on the welder and worst case can just unplug it. But a disconnect looks pretty cheap and easy to add so if this is code or better Iím ok.

Just donít get what itís for?

Use #10 wiring for a 30A circuit.
If the welder plugs in..... no disconnect is needed.
