1000 watts = 1kw so 32200 watts = 3.22kw
powered off the mains its still = 13amps * 240 volts = 3.12K

He needs a 3.3 kv to power the welder .
Thats a big generator to power his welder at max output.

portable generators usually come in around 2.2 kv .
Just enough to boil a kettle and no more.
Thats assuming its a 2kw kettle .
Trust Me .
LOL

Be carefull with your answers this could be an Iraqi trying to
obtain western secrets of arc welder.That chopper could be back
in the air tomorrow.

LOL !

Dont forget its low voltage....32kw @ 240v = the national grid.

You wont weld it, you'll vaporise it.


ps, cant remember the conversion thingies....13 amp should be ok.

bit late don't you think? wonging is in north midx nursing burns and shock

[gerry2] 24/3/2003 19:39

wonging

Watts = V x I = 230 Volts * 140 amps = 32200 watts .

generator required 3.3 kva should be ample or ADVFN

LOL

wonking

did your welder explode?

ARE YOU OK?!

pizzaman, ok thanks for the info, but this poses a question, i have used the generator via an extention lead with a max rating fully unwound of only 3000 watts, so are you saying i was pulling 6000 watts through this lead? what is I and R?

R= resistance and running the extention lead could be a problem.

6Kw will do you just fine IMO DYOR

PS i got one for sell in my garage and it's full of petrol LOL!

If the welder runs off a 13A household supply the maximum power needed is
13A X 240 V = 3120 W (it is slightly more complex due to Power factor and other things but close enough)

The welder will not use all of this but you should be looking for a 3KW genny

[pizzaman] 17/3/2003 10:44

still needs a generator of around 6kw even if he is running only a 3Kw welder on it

wooden5

AYE!

[wooden5] 17/3/2003 10:43

in actual fact the name 1500 gives you a clue.i would say power consumption is 1500 watts

[wooden5] 17/3/2003 10:36

dell
correct there will be info on max amp draw on the machine x that by 240v will give you the size of the gen set needed.a welder transforms the 240v down to very low voltages high amps

[pizzaman] 17/3/2003 10:32

dell

AYE!

[dell314] 17/3/2003 10:31

Power = VI

Assuming your welder runs on normal mains via a normal 13A plug, it can't be any more than 3KW or the fuse would blow instantly.

(240Vx13A=3120W absolute max)

DYOR.
(I would expect there to be a power consumption or input current printed on the welder somewhere)

[wonging] 17/3/2003 10:28

optimist, ok thanks for the info, its a conventional arc welder by the way

[pizzaman] 17/3/2003 10:25

I also= AYE+EYE

[optimist] 17/3/2003 10:20

If it will run on 230V then around 3000 VA should be enough but you will need more.

Arc welders put a highly inductive load on the supply which ups the current requirement and may not do your generator much good especially when you short circuit the welding tip.

Is yours a CO2 or conventional arc welder? If the latter I suggest that you look for a combined generator and welder. Also try to get something that will give you more than 140 amps.

I=current
R=resistance
