have to check my maths but
radius x radius x Pi gives area
0.3 x 0.3 x 3.141 = 0.283 mm2
there are 1000 cubic millimetres in a cubic centimetre.
1000/0.283 = 3533 . so 3533mm of 0.6mm wire is equal to 1 cubic centimetre.
1 cubic centimetre of steel weighs about 8 gramms.
5kg or 5000grams divided by 8gramms = 625. or 625 cubic centimetres of wire equals 5kg.
1 cubic cm is equal to 3.533 mtrs of 0.6mm wire. so 625 x 3.533 equals total wire length on a 5kg reel or 2208 mtrs (2.2km).
At 130amps you will be using around 8mtrs a minute of 0.6mm wire or you have 276 minutes worth of welding.
Thats 4.6 hrs worth.
Acording to a cebora 130amp its rated at 2.2kw. 2.2kw x 4.6hrs is 10.12 kilowatt hours. its about 12pence a kilowatt hour?
So around £1.21 pence.
needs someone to check my figures.
To expensive for you bawjaws? or cheaper than you thought
sorry for the late replies, internets playing up, naah im not trying to look after the pennies, its coz i use my grandads garage and he keeps on moaning about the amount of electric it uses (like he cant afford it ), christ his tumble dryer uses more! is that 1 pound odds for 5kg or 1kg, wow electrics cheap i thought it would be about 30 quid for a reel,
baw thats for a whole 5kg reel, the electricity is a minor cost of welding. The wire is more expensive and so is the gas. Infact i could say i would use more than £2.00 worth of tips and shrouds on a 5kg reel lol
Its suprising how little the electricity bill is for my place, given that there are usually two 300 amp migs on full knacker most of the day, bandsaws going, grinders, drills etc, lights on, radio on, kettle on!
