been browsing a few,ready to buy and just curious if anyone happens to know how much electricity they burn.

 

Depends what type you buy and what voltage you run it off of. I purchased a Miller 375 for the last shop I worked at. Running it off 110v, it needs a minimum of a 20amp breaker.

You also need a good air supply so the electricity of an air compressor needs to be included. The 375 needs a minimum of 4.5 CFM at 90 PSI.

 

You want to know how much power it takes to support running them or how much they add to your power bill?
I have a miller 625 and with out counting the power the air compressors need the plasma cutter alone uses slightly more power than a home clothes dryer when turned up to full power.

 

Amps X Volts= watts. given stephen's 110v at 20amp thats 110X20= 2200watts

now my bill comes by killowatt hours. so kilo=1000. therefore 2200/1000= 2.2kilowatts

and they charge about 10 cents per kilo watt hour, so using the plasma for one hour would be roughly 10X2.2= 22 cents. cheap, but adds up fast!
