Welding receptacles

[j87]

Is there a requirement that a welding receptacle and plug be mechanically locked in before use, either through the plug being threaded onto the receptacle or a built in interlocking device? Does the plug have need something to hold it in place?

I have seen plenty of 120V welders that come with a regular 15A plug on it. Nothing unusual at all.

Thanks for the reply. I should have been more specific. This is a 480volt receptacle

I looked in article 630 which covers welding equipment and saw nothing about receptacles at all.

It may be local code or practice. But with 480 its not a bad idea.
