3, You don't have to disconnect when using stick/rod if the earth clamp is on the same component you're welding.

To me this is risky nonsense especially considering modern electronic systems, I'll still disconnect regardless. That said I can't MIG or TIG to save my life and my rod welding can be abysmal.
