You do realize that you pay for electricity based upon KW/Hour, and that a Miller 135 at full nut draws [email]20amps@120[/email] volts (2400 watts) and a Miller 175 at full nut draws [email]20amps@240[/email] volts (4800 watts).


You say it yourself, though. Full nut of the 175 is twice the wattage of the 135 -- hence twice the heat. So to get the same 2400 watts out of the 175 I'm only drawing 10 amps. Also, since I am only drawing 10 amps, my duty cycle has also increased substantially over the 135 giving all she's got.
