In 2010 I purchased a 15" Clausing Colchester Lathe and a Do-All vertical band saw, which both have three phase motors. In my garage I just have single phase power. I could have just installed a vector drive on each of these just like I did on my Bridgeport. Instead I decided to investigate if it was possible to use either a rotary or a digital three phase convertor for these two new machines for the present, with the idea of using the three phase convertor in the future to power a Dynasty 350 welder. The reason for doing this is that the Dynasty 350 has a much better duty cycle on three phase compared to single phase. After a discussion on this forum I decided to purchase and install a Phase Perfect PT-330 digital phase converter. I have powered my lathe and saw on the Phase Perfect for the past five years without any problems
My friend who is an account manager at a local welding supply company just dropped off a brand new Lincoln Aspect 375 TIG welder for me to try out. The Lincoln Aspect 375 also has a reduced duty cycle on single phase similar to the Dynasty 350. I didn't want to smoke the Lincoln 320 amp water cooled torch that came with it so I limited my welding to 320 amps. I didn't have any problems welding aluminum at 320 amps with the Aspect 375 running on my Phase Perfect digital three phase generator.
Attached are three pictures.
The first picture shows my power setup in my garage. The panel on the left is my single phase distribution panel. The next panel to the right is the three phase distribution panel. In it I currently have one circuit breaker for the Lathe, one for the Do-All saw and the third for the three phase welder. The next panel is a relay box to start the phase perfect digital phase converter. The last three boxes to the right are the disconnect for the lathe, Do-All saw and three phase welder. The big box on the top is the Phase Perfect. The green stickers on the panels indicate that everything was inspected and approved by my local electrical inspector.
The second picture is the Lincoln Aspect 375 welder, which is hooked up to my three phase power.
The third picture is a piece of 1-1/2" round stock welded to a piece of 1-1/2" square stock to try it out.
