Disconnect got welder

[Cleveland Apprentice]

Hi,

i am running a 240 volt, 50 amp line to an electric welder NEMA 6-50. I see that a disconnect is required but can a CB serve as a disconnect 25' away line of sight? Or do I need a disc at the welder itself. I don't believe the welder has a built in disconnect and I don't believe a cord and receptacle would satisfy the requirements for a disc. I'm wondering if a CB 25' away line of sight will suffice? Thanks

630.13 Disconnecting Means
An identified disconnecting means shall be provided in the
supply circuit for each arc welder that is not equipped with a
disconnect mounted as an integral part of the welder.
The disconnecting means shall be a switch or circuit
breaker, and its rating shall be not less than that necessary to
accommodate overcurrent protection as specified under
630.12.

I don't see anything that requires the circuit breaker to be less than 25' away or be line of sight.

The line of sight rule may be for LOTO reasons.

By 630.13, could one disconnect (breaker) serve multiple welders?

If a disco near the unit/LoS is not required, why even have 630.13? Are branch circuits ever allowed w/o OCPD? Does "in the supply circuit" preclude the use of the welder breaker in the (sub) panel?
