Miller Synchrowave 180SD power cord

[jonesy]

Hi Guys,

I just ordered a Miller 180SD and I need to get power run into my garage for it. Does anyone know what 208V power plug style I should have installed, what plug is on the welder when I get it? Will 208V 50a be enough to have installed?

Thanks,

Mark

Why 208? Why not 220?

jonesy,

The Syncrowav 180SD is rated for a 230v, 54amps input. It will work on plus or minus 10% of that input, which brings it to a minimum input voltage of 207v input. If your line power drops below this you will probably have problems. I suggest metering your actual input voltage and then giving the guys at TIG Service a call, 920-735-4505, just ask for TIG Service.

Take care of the dream catcher

Thanks guys. Can I ask the electrician to install 220v instead of 208v or is this something I have no control over? So it sounds like a 60amp breaker should cover it.

Thanks,

ASSuming this is in a house, the actual voltage will be whatever your residential service provides. Household voltage used to be Nominally 110/220, but has increased slowly to where it is now closer to 120/240. The voltage at my house is 121/242 on average.

In other words, there is some variability between Nominal (in name) and actual voltage. The good news is that as the voltage has increased, the amps required decreases.

The newest SD 180 I seen,does not come with a plug.So that answers that!They had the wire hanging out though.

This thread has a picture of a good choice for a plug/recepticle.

If this is a new circuit and a new welder with a new power cord, can anyone think of a reason NOT to use a four conductor plug (instead of 3 conductor)?

The extra conductor was added to NEC in 1996 for certain household appliance circuits (like clothes dryers), but I don't know about welders. My dryer uses NEMA 14-30R, for example.

There are certainly a lot of plug options:

FWIW, I tested mine today and it was 125/250V. It appears to have gone up since I checked it about a year ago.

208 is a three phase voltage. If you are hooking this welder up at your house 95 % of the time you will not have three phase. In a 208 3 phase service you will have 3 legs all with 120 volts or there about. They will all be out of phase with each other. If the phases were all the same your equipment would be without power every time the sine wave crossed the median. Voltage will vary all day long as power is used along transmission lines. It may not be the same 5 minutes after you check it. Voltage varies, it might be 110 or it might be 128 but it won't vary much over that. Thats why they make 130 volt light bulbs. The filaments are slighty more stout than normal,so they won't blow out if the voltage rises. There are lots of 220 plugs.You can always cut the ends off and buy a plug or a wall plug that will go together. Dryer and stove plugs are cheap and generally heavy duty enough for welders. I have a 50 amp stove outlet on my idealarc 250. You don't always have to have a 4 wire plug on a welder.On a the 3 wire plug,you have the 2 -120 legs and the ground wire for the welder frame. 4 wire cords are for appliances that have 120 timers,controls,lights etc. that require an insulated neurtral and need the frame grounded for safety. Hope this helps!

No reason not to, and no reason to, since the welder comes with a 3 conductor cord already attached. If its sharing a recepticle with a dryer, then the 4 prong plug would be appropriate.

HEY JONSEY..........I ANSWERED YOUR QUESTION ON THE MILLER WEB SITE BEFORE I WENT HOME LAST NIGHT.......... BUT MY GUESS IS YOU ALREADY KNOW THAT.................THE PLUG CONFIGURATION IS OF YOUR CHOOSEING............. BOTH THE MALE AND THE FEMALE................. ARE WE HAVEING FUN YET.......... ROCK....................
