Ironically, I'd refer you to what B-A-S wrote in his follow-up posts - when he wants to, he can be helpful. When he's not in the mood, he can be extremely counter-productive.

Any chance that, instead of simply insulting the OP, you could help guide them by specifying what the issues may be with his approach? Or is your intention simply to once again send a new poster packing and repel him from this forum?

It's made perfectly clear later in the advert why you should buy one - it's to protect you from "crowning calamity" caused by "famous brand of electric water hotter". Clearly, if your electric water hotter is made by someone you've never heard of, then you will be quite safe; Hey... now...

Olde worlde arc welders could be oil-cooled, or very high-end / high-duty welders. Nowadays tho, as you might expect, moving a large quantity of air across the transformer is an easier, more portable (you're supposed to empy oil-cooled welders before transporting them) and cheaper method.

Is it frowned upon to mention other forums? I frequently refer people on http://www.mig-welding.co.uk/forum/ over here for questions on electrics...

Jeez Dan - sorry, mate - we forgot you were there :lol: Nah - you're good. At this end, Sealey, Clarke, etc are all pretty decent. 5mm is right at the limit of what a 150A MIG can cope with but, with a bit of careful filleting, you would be able to do it. If you really are going to be...

Nope, not really. Yes, you can get oil-cooled welders (water-cooled much less so). Oil-cooling does tend to be more prevalent in arc-welders, rather than MIG, though. But we're conflating two different arguments, here. MIG welders will be air-cooled all the way up to the £2k / £3k and beyond...

If it's not a misprint, then that's appalling. Any 150A MIG needs a dirty great fan on it to keep it cool and get a decent duty cycle. To be honest, speaking as a hobbyist welder, 50-60% at 150A would be good enough for me, giving the clamping and tacking required, but 30% way down at 105A is...

It has a maximum input current of 20A @ 230V AC, and is most efficient (unsurprisingly) at the much lower input current of 7.9A @ 230V AC, which equates to it's 100% duty cycle of 30A (DC output current). Good for welding car panels :)

Unfortunately, most single phase MIGs are sold with a 13A plug, but the figures don't lie; 4.5KW is almost 20A at 230V. Having said that, given the poor duty cycle (as mentioned above) at 150A DC / 20A AC, chances are a 13A fuse or 16A MCB may not trip. I don't like it, though, and...

MIG welders typically operate at a fixed voltage of around 30VDC so that's (roughly) where the 4.5KW comes from on that "150A" welder. And yes, that would suggest that at full tilt, the 150A welder will need just shy of 20A at 230V. It's interesting to see, as an aside, that the duty circle...

In reality, though... does anyone actually do this? I know literally dozens of people who have welders (4x4 club with lots of rust) and I'd never heard of asking permission from their DNO to run them. I'm hoping not to get into a "you must follow ze rules" debate, just an honest answer...

Glad to hear it all worked out in the end - thanks for updating us! As a resident of Scotland, where an offer to buy a house is binding, I'm just amazed that English (and Welsh?) law allows a seller to pull out at pretty much any time, and that this then leads to these kinds of games. Move...

Thanks for coming back to us. At least you listened to the advice - many people don't :) I don't see any issue with you putting in the conduit as that's not part of the electrical installation, and it certainly makes sense to get that done now, if you're doing other work.

[/url] Well, you're absolutely correct that both of these expect a 16A feed to pull the 3.6/3.5Kw they'd be looking for. There are defo ovens available that are under 3Kw (13A) so your choices are to shop around, or get an electrician in. To answer your other question of me; yes, an...

You're about to incur the wrath of ban-all-sheds (and others)... Anyway, you just said that you would ... "use safe materials in a house you were going to live in". But in your original post, you mentioned renting it out... The regulations are in place for a reason, primarily for your...

Welcome to the forum! I think your belief that the person on the end of the fine doesn't understand what is involved is correct. I can't see the electrician being too impressed at having to chase (cut) new cable into the wall, possibly add a new MCB (circuit breaker), possibly even replace...

Sigh... :roll:
