Miller Shopmaster 300 Wiring help

[kidroc2133]

New to forum, but not new to welding (over 10 years experience.) I just purchased a miller shopmaster 300 that has been completely rebuilt. I just need to know what breaker is needed to run in the electrical panel and also what type of disconnect I will need? I will be hooking it up directly to the disconnect as I will not have to move it around my shop it will stay in one place. It is set up to run on 220v. Any help is appreciated.
Manual for the welder based on serial number below.

From the manual you posted. Looks like it requires a 125amp CB/Fuse.

ok, what about a quick disconnect? non fused or something like a time delayed fuse and what size? Manual doesn't state what kind.

Grid didn't copy well from the service manual But it calls for a 125 amp standard fuse or circuit breaker. This allows operation to 300 amps. You can get away with a smaller service if you stay below 200 amps of welding current.
