I have found a 'compound' to do my project work in but there is no power. Is there anyone who knows there amps from their watts and can advise me if I could buy a low price generator that will power a mig welder and angle grinder.
Oh yes I need the mig welder too.
Any advice??

get a generator welder set.

Welders do tend to be quite current hungry things so you'd probably need to go for a hefty (and expensive) generator. The advertised peak output (e.g. 4500W) is likely to look healthy but it's worth asking what the duty cycle is - how long can it deliver that peak output for? How long can it deliver, say, half the peak output? If you're welding in very short bursts it might be a bit more feasible. A lot depends on the power requirements of your welder and how long you want to run it for. Having said that, a lot of domestic duty welders will only run for a little while before needing a rest to cool down too. Hand held power tools are much easier for generators to cope with, and I once spent an afternoon wire brushing a friend's boat armed with an angle grinder with a wire brush and a cheap generator we'd got from B&Q for about £130. The generator seemed perfectly happy. The grinder was about 650 W as I recall.

Good idea. They've often got sockets on so you can run other power tools too.

Could always get an oxy/acetylene set and gas weld it.

I have done some reading and have come up with this, a household socket is 240V and typically rated at 13A.
The maximum available is 240x13= 3120 or 3.1kVA (W).
I know that my welding is not very continuous, so provided I stay to a hobby welder and run it sparingly, I should be OK with a larger 'small' generator.

For the price difference between a 3Kv and a 6Kv... just go for the 6

I bought a road compressor recently and that is also a 6kv generator so that might be another alternative (albiet rather large)

We had this problem when we worked in the fields a bit. a 3KW genny was the minumum to be able to run the sheep shearing gear. I imagine a welder would be just as power hungry. IIRC they use KVA now rather than KW, and they're not the same! 3KW is something like 3.2KVA I think.... can't remember... google will tell you. 3KW minimum I'd say.

The search for a generator is hard, I don't have an endless budget but need one soon to start project properly!!

Get one with a Honda engine... That aught to filter it a bit.

seen quite a few petrol welders for sale for around 100 on ebay recently

Always get the biggest you can possibly afford. I've often been disappointed with tools that are too small and too puny but never by something too big or too powerful.

That's what Minty told me..
