Is it okay to daisy chain a 30 amp 240 volt circuit to multiple boxes? I have a customer that wants to be able to plug in his portable welder in many different locations. I looked through article 210 branch circuits and couldn't find anything that says no. Just thought I'd make sure before I did it.

As hard as it is to believe, I cant find anything in the code that will say no. As long as the breaker is a 30 amp its ok.

What is hard to believe about it? Are the extra 30A recpts going to start spitting fire or something?
Because you have multiple receptacles on that circuit, you are now limited to a max of 80% of 30A for a given receptacle (210.21(B)(2)). Could be a problem with a 25A nameplated item. However, I don't know who would ever catch that violation unless it was plugged in at the time of inspection.
If you label them as Welder Use Only, you can even go with a larger breaker than 30A.
