I have three generators in my generator shed... a 7.5kw four-cylinder, a 12.5kw four-cylinder, and a 35kw six-cylinder. I have a contactor panel on one wall that selects whichever generator, then a feeder goes from that point, to a transfer switch next to my main distribution panel. That main...

"The only reason I would consider it is, if I was getting the welder dirt cheap ! " :thumbup: THAT... is the only reason why I bought one, took the time to do this, and then published it for the world to see. There's lots of enthusiastic guys out there who would love to have...

Hi Wiz- Well, the assumptions of theory are pretty close... but the part that doesn't 'really' matter, is the 120 vs 90 degree phase shift comparison. All three coils are operating with 240v across the leads. The CP-200's original configuration, rewired as I did it, is actually applying LESS...

Erik- There's many reasons why a three-phase welder conversion fails to yield good results, and in most cases, the biggest part that I've seen, is that first, guys simply don't understand how the welding transformer works, and second, how it's operation relates to the current and voltage that...

Hi Dog! The MM252 is a nice unit- it's based on the standard MM250, one of which we have in our fab shop here. One of my co-workers bought a new MM252 for building derby cars... the auto-set feature was his big reason, and I think the big attraction for these IS the auto-set. Not as powerful...

Oh- I like the lawnmower deck re-use. I'd rather have steel than plastic wheels, but use what' ya got. My Handler came to me on a butchered-up shopping cart, but I run it hand-portable on fluxcore now. If I'm workin' a job where I hafta shuffle it around, I strap it to an old handcart used...

Hi Eric! Don't glue yourself into theory... What you have here, is a statement that seems logical, but in reality, it is NOT correct. When you build a rotary converter, you actually DO generate three phases, and they're very close to 120 degrees apart, but the phase relationship will vary...

Hi Guys- Someone forwarded a link to this thread, and told me to check it out, so I did... Sorry about not having updated the CP-250TS thread for a while- my company has been inundated with projects for the last year, so I haven't gotten much shop time. The CP250TS is a very 'early' design in...
