thanks for the info tritowns

i did some more checking on how much eleci i would use i did find this info from the welding forum im on thoe

Ill do some serius maths here, for anyone that is worried about the electricity use.

ill assume you (on anyone is using 0.8mm wire and flatout 130amps)

at 130 amps the wire feed should be 5mtrs per minute. one cubic cm of steel weighs 8gms.

5mtrs (500cm) of wire is 500 x (0.04 x 0.04 x3.141) = 2.51 cm3 (radius square times Pi = area) (area x height/lenth = volume)

2.51 x 8 grams = 20 grams. so 1 mins welding uses 20 grams of welding wire. the baby reels are 0.7kg or 700 grams, so 700grams divided by 20 grams = 35 or 35 minutes worth of welding from a baby reel. Ill assume that at 130 amps the machine draws 3kw, truth is more like 2.2kw.

35mins/60mins = 0.58333 of an hour. 0.583333 x 3kw = 1.75kwh. at todays prices of about 12 pence per kw that around 21pence for every 700grams of wire laided down.

if you run a 5kg reel, then its about £1.50 per roll or a 15kg reel is £4.50 a roll. obviously if your running at lower power or higher power than 130amps the price will differ slightly

check my calculations they might be wrong, but hopefully that clears the cost of welding up

i wonder what others info would say on there energy consumption
