we have a new laser cutter on its way to our factory and unlike all of our other machines, this one is a high powered fiber laser that requires 380 volts...I was told by the company that I need a 220v to 380v step up transformer in order to get this machine working but im sort of at loss as to where to start.. i had a local electrician here yesterday to quote running a new line for the machine and installing the 220 to 380 step up transformer and I just received a very high quote, much higher than I imagined it would be...the invoice shows just the cost of the transformer alone is $4500 bucks....am I missing something or is this a realistic price ? ..the machine requires 380volts 3 phase @ 26A is there a cheaper way to achieve this?? we have standard 220
