[alfa] Electrical Question - NAC

[Alfajgt1@xxxxxxx]

Sorry about the lack of Alfa content, but I'm afraid the only experience with 
electrical engineering I have had was when I was about three years old and 
stuck a hairpin into a wall socket. Suffice to say, I know virtually nothing 
about the subject so have a question for the better educated Digesti. 

Taking welders, for example. Is there any way to tell how many 
watts/kilowatts a unit uses by looking at the specifications? In this case the welder works 
on 230 volts and draws 180 amps.  I'd like to know how much it would cost to 
operate the bugger, however my electrical knowledge is limited to the extent of 
knowing that a 100 watt light bulb uses 1 kWh when lit for 10 hours. Reply 
off-Digest if you wish. 

TIA,
