Hi, the maximum power you can use at home, is whatever the supply will allow, in my case it is 60A at 230V. I have a 30A socket to plug in my inverter welder, and it will struggle to work on anything less, basically for the arc striking threshold but doesn't use that much during actual welding, and my old manual metal arc welder has always blown a domestic plug top fuse if I use the top end of the output, so that gets plugged into a 16A socket.
So what makes the difference from a Plasma cutter to a TIG welder or an inverter welder, as far as emissions are concerned?
I will say that my nearest neighbour is about 100 meters away, and the local mains transformer is about 500 meters away, and I haven't had any complaints about any interference from anyone.
Regards Nick.

Industrial TIGs and inverter welders can suffer from the same issues This is only talking about plasma cutters because that was the original subject. Plama cutters do tend to be worse because the plasma is produced by radio frequency power.
Lack of complaint is not evidence of lack of interference. A user may not associate disconnections / slow responce of their internet or failure o a electronic device (due to harmonics) with your hobby activities. It is also hard to track down the source without specialist equipment. Not like radio amateurs who have to give their call signs and often have large antennas.
Hi Robert, there seems to be an awful lot of companies selling Plasma Cutters where the public can buy them, even two well know High Street retailers, and none of them say they are for industrial use only, and have a looked through the instruction manual of one of them, the only environmental protection that is mentioned for private households, is the disposal (WEEE) and not to include them in household waste. So are these people wrong for selling such things to the public, or not saying they are for industrial use only? Furthermore, I've looked online for regulations about the use on domestic power, and haven't found anything to say they shouldn't be. I don't actually have a plasma cutter in my garage, and don't have any immediate plans to get one. I have used them at work, and in one of my jobs the workshop was next door to a private house.
Regards Nick.
