Our Powermax30 XP is a dual voltage design....because there is a strong demand at that power level for the portability and ability to be able to be plugged in almost anywhere. The 30XP has similar thickness ratings as compared to the Miller 40 Amp dual voltage unit. In fact when operated on 120 volts the 30XP produces more power than the Miller on 120 volts.

When we planned for the 45 XP, it was decided that this is a machine that will get a fair amount of industrial use, a machine torch and interface, and that the majority of users would have 240 volt power (or generator power) available. We do "Voice of the Customer" market surveys pretty regularly and feel that we do understand what the majority of users want....those that need a dual voltage can go with the 30 XP or the Miller offering (which has less power on 120 volts than the 30 XP!, slightly more when on 240 volts, a design compromise). The 6500 watts of cutting power produced by the 45 XP is a lot more than the 5600 that the Miller unit can produce....so you will see faster speeds and thicker cutting with the 45 XP, as well as the ability to mark and precision gouge down to 10 amps.

Awesome explanation as always Jim. The trade-offs in making the 45XP a dual voltage unit seem to suppress its advantages and key features, which I can say with first hand experience that the compromise wouldn't be worth it! It really shines in the DV-compromised areas. It's also good to know that a DV unit requires more than just a software tweak and a pig tail. Plasma considerations definitely seem more involved than those of welding machines when looking at DV.
