That was a matter the local council would have been interested in.
The DNO were only interested in the disturbance his equipment was causing to the voltage on the local supply network.

If he wasn't running a business the people around him wouldn't have complained.
The complaints were made to the various electricity supply companies ( and maybe directly to the DNO ) about lights flickering and other indications of voltage fluctuations. As far as I know no-one complained or mentioned the business operation.
1) Yes they would. Their lights weren't flickering because he was running a business, they were flickering because he was using too much electricity.
2) It was not because he was running a business that the DNO got involved.
Did you actually read any of the other topic?

In some respects, of all the electrical machines/devices for use on a 230v domestic supply.
Why don't they carry a Warning to the user of this problem, if it is a problem.

Maybe because such a warning might put some people off, and hence reduce their sales/profit?
When buying a car, have you ever been 'warned' by the seller that you would need to have a valid driving licence in order to be allowed to drive it?

If you buy bricks and sand and cement, do you get warned about Building Regulations and planning laws?
I think if it was a common problem/issue then they would have, however given how rare it is I guess its not even an issue.
I doubt that there often are problems/issues associated with ignoring the contractual requirement to get DNO permission to use such equipment - not the least because the average DIYer/hobbiest is only very rarely going to use the items, and usually only for short periods.
However, as BAS and I have both suggested, even if the problems associated with use of such equipment were common, I don't think it's down to the supplier to issue warnings - and we've both pointed out (with just two examples, put of countless possibles), there are countless examples of things which are sold, the use of which is associated with legal and/or contractual requirements or constraints, but you'll only rarely find the manufacturers or sellers issuing warnings about this.
Kind Regards, John
Hi John
In a similar vein, is there a list of items that you don't need to contact the DNO to use?
I think you'd have to ask your own DNO.
The examples given earlier in this thread referred to equipment actually causing interference with others, which I hope everyone would expect the DNO to take action against. That is however a different issue from whether or not prior permission should be sought.
Regarding the original question, if the welder worked OK on an older installation with 30A fuse then it is possible it will trip a 32A MCB. If it were me then I'd just cross that one when/if I come to it. My 150A welder worked fine on B32 in the past, and currently it's used on a radial with a B20 without problems.

I've used invertor welders on site and they always seem to use less current.
Longer extension cables are not a problem I find. And less pull on the genny.
With the old transformer units sometimes in the rain you would see the steam rising off the 240v extension cable. Usually when a nail is used as a fuse in a 13amp plug.
And then you have features like "Auto-adaptative arc force" "Power surplus", "Built in hot start" etc etc with the invertors.

I've used aa mig , an arc welder and a 2.5 hp compressor and it hasn't tripped a 30 amp MCB , all obviously before I've read all this !
If you do it in daylight , none of your neighbours have their lights on and won't be aware of any dimming.....
