    RFI From Inverter

    Could you not take all your findings to the british standards people and explain that the requirements need to be changed?? What about trading standards?? Mind you, they seem to only be interested in the little man, childish things like people selling fake cd's at car boot sales. In my own...

    How are they able to import and sell the chinese crap if it does not comply with whatever "anti EMF" regs there are?? Does not "CE" marking indicate [or be supposed to indicate] that the stuff does comply with whatever regs?? john..

    Plastic gas pipe to buried metal pipe...

    Hi there. I followed the link you provided and it is telling you total crap.. That calculation is totally wrong. When testing to see if a part is "extraneous" and hence needs bonding, you measure the resistance between the part and the MET as they describe, BUT, the MINIMUM reading is...

    Transformer welder: my puzzle

    Plasma cutting is what you want to worry about. My own Lincoln PC65 will cut 18mm plate with a current of 65A at a voltage of 106V. The open circuit voltage is a lethal 540V made even worse as you have HF start at about 10,000V.. john..

    Transformer welder: my puzzle

    Hi Poni, The actual arc voltage when you are welding will be around the 18 to 40 volt mark, but the open circuit voltage will be a minimum 50V, but in the real world anything less than 80V, makes the set horrible to use, so that is the norm.. Pipe welding you want a good 90V due to the type of...

    Transformer welder: my puzzle

    In theory.... In practice you will find a few [old] AC machines with an OCV of about 90v [so peaks of 127v] or even 100V OCV Very many DC machines have an OCV of 90V too. They will shock you ok!! This is why what everyone calls the "welding earth cable" is not, it is the "welding return...

    Transformer welder: my puzzle

    Ok, a bit of a question from me!! How is it that the secondary windings of a welder are separate from the primary ones, AND, apart from the welders designed by "experts" many years ago, the secondary is not connected to the case of the machine in any way. [It is not earthed] So, the secondary...

    Tuya circuit breaker

    Hey, come on.. He is trying to do the best thing or he would not be on here asking. It might be a class 2 appliance for all we know. I do think that it wants more looking into. Perhaps if Antek was to tell us exactly what sort of vending machine it is, make and model.. john..

    Well, they ARE to blame as it is them emitting the interference. Be the same as if i decided to heat my house by burning car tyres and then claimed it was not me making the smoke. They are causing a public nuisance. Public nuisance is now a CRIMINAL offence... Read this adn hope it helps...

    The u8ltimate answet [if you have the evidence that it is them] is a court injunction as you are entitle to peacful enjoyemt of your property.

    I will add here, that they are that shit that they WILL NOT let you see your contract with them, AND, they are being investigated by the ombudsman, and even worse, ofcom THEMSELVES, for blocking people trying to leave...

    Exactly the same as me then, i had Outlook express and then thunderbird as it was the closest. As for your emails then, you have a shock coming.. Virgin have been trying to sort things for me [and the myriad others] for days now, but the truth is that we are all just being strung along. Best...

    I started with them back in the NTL days before virgin were even invented. There have only been a few problems, but when you have these problems, Virgin will simply not be told. I wish i had done screen shots of the stuff i had.. Below is a screen shot of something that someone else has...
