What amp power points your welder run on?
What amp power point does your 150 amp welders run on, read somewhere they need a 30 amp supply?
Whats the biggest ampage you can run on a 13 amp socket?

MORE POWER
Craig funnily enough its 13 amps, the cable run behind the socket and more importantly the fuse board will not like it too much if you start trying to
draw much more than the 13 amps from your typical domestic ring main. Suggest u keep a fire extingusher handy if you do, but the fuse should trip out
long before thats your problem. Have a look at a 30 amp socket and the wire diameter rated at thirty amps, should be self apparent. The heaviest draw
in a domestic house cct will be your cooker feed (if its lecy).

I think you'll be getting near the limit of a domestic ring main with a 130A welder - but only if you run it at full power. You will rarely run
it at more than half-power most of the time when building a Locost.
I have a 130A MIG that plugs into the garage ring main. I also have a 150A TIG that has its own dedicated 30A socket and spur from the fuse box (not
hard/expensive to install, preferably by an electrician!).

Okay thanks for that lads, Just wondering before i buy a welder what i can run on the standard main,This house is council owned and i dont want to pay
to electrical work done on a house thats not mine,having said that the cooker points not far from the back door mayge an electrician could put a spur
on it and a blue 240 volt socket so i could run an extension to the garage from it?

Same here, never tripped out. It does make the lights in the house flicker though. Interestingly my Tig doesn't have that effect despite
chucking 40,000 volts about, probably because it's inverter.

Same here runs fine at full power. My father's a chartered electrical engineer and has no problem with me using it.
Lights go funny and computer monitors do something strange so might be worth getting whoever's working on the PC to save their work frequently
though! 
Cheers,
James

Craig single phase 150amps (Welding machine on full tilt boogie) is shoving it, especially if the wiring is "old" However I suspect it
wont be a problem as long as u are not continually welding. If you are using a Tig machine with HF startup it can wreak memory on hard drives if u
are drawing power from the same loop, especially AC/DC welders. Not advised for people with pacemakers or damp welding gloves and likewise standing in
puddles, dont half make you breakdance

I use a 170 on the shed supply which runs off a 40 amp fuse and it doesn't make the lights flicker at all. As mentioned earlier you will not use
anywhere near full power on a car build and if you do use full power on a diy mig it will cut out before the main overheats due to the duty cycle,
lucky to get 25% at full power.

I went into the RSPCA office the other day. It was so small you could hardly swing a cat in there.

I use a 170 on the garage supply - if I whack it up to full power it blows the CB.

if you do need more power its not very hard with a modern consumer board. I had a mate stick a 25 CB in for the plasma cutter, looks easy if you know
how, like 5 mins work. i dont know how myself, but that isnt the point!

Not had any problems with computers and HF tig - my server's on a UPS, so that wouldn't be affected anyway, but none of the other
computers have objected at all.
