  • 220v or 230v , is there a difference?

    Hello,
    This is my first purchase of a Mig Welder.
    I'm looking at the Hobart 187.
    My question relates to the power supply.
    I have a 220v 30 Amp single phase outlet in my garage.
    The Hobart 187 says it requires a 230v single phase 21 Amp power supply.
    Do I have to rewire the outlet or will the 230v Welder run on my 220v outlet???

    Thanks

    My "220" measures around 250 volts. You will be fine, welcome to the forum.
    What do I know I am just an electronics technician.

      Most voltages today are a little "hot" everything will be fine and you will love that welder!!!

        Callcover - there are really only 2 common residential voltages in us in the US. One is the 115/120/110 stuff (its all the same, but different folks call it differently. the other is 220/230/etc. Again all the same stuff.

        Utilities try to keep your voltage to within about a 3% band, but if you are further from the nearest substation than your neighbor he will most likely have a slightly higher voltage than you. Your own voltage will also go up and down a bit as your AC unit comes on and off, or you throw that big welding load on the house. Its a bit more complicated than all that, but all you really need to worry about is whether you need 1XX or 2XX type stuff.

          Your household current is usually 230v +/- 10 volts. So it could read 220, 230 or 240v. As long as it never reads above 240 or below 220. When this happens, you usually have an odd smell...

            We are on a 120/240 system.

              Hello, and welcome to the party.

              Power standards have evolved over the years. In today's USA power distibution world, the standard secondary distribution voltage for residential service is 240 volts AC, single phase. The resultant "line to neutral" voltage is 120 volts AC.

              Appliance ratings of 115/117/120/125 volts in today's world mean nothing. The thing will run if you plug it into a standard receptacle. The most common voltage you will measure is ~120VAC.

              The 240VAC appliances suffer the same fate. 220/230/240 = the same thing. The uaual measured voltage accross the two phase legs today runs 242 to 250 volts.

              Your 187 will be thrilled if you just plug it into a 30-amp, 240V recptacle!

                  agreed

                  Just to fully beat into the ground what the others have said, there is no material difference between 220, 230, and 240V. I measure my "240VAC" outlet. It hovers around 243 volts. Measure yours. If it is significantly less than 240, then I'd be worried, not for the welder, but what the heck is wrong with the house's wiring!

                    Yes. I've worked throughout Nevada, California, Arizona, New York, Maryland; Colombia, and Mexico. So far, everything's been 120/240V.

                    If the appliance is rated for 220, 230, or 240V, your household 240V will work just fine. The only time you need to wonder is if it's rated 208V, which is common for industrial 3-phase machines.

                          Why do they label these machines for 230V? Is it because everything thinks 220V is normal, so they just split the difference between perception and reality?

                            Who knows? They still sell "115V" appliances!

                            You should grab a couple of cold Dos XX, grab Amy, snuggle up, and forget about this meaningless junk!

                              My guess is because "230V" is very very close to the centerline of the 208v to 254v recommended designed operating spread for the manufactire of equipment in the US of A... I guess 231 volts would be the real mathmatical center but I can imagine the hub-bub caused by putting "231 Volts" on a label.

                              This is in reference to our single phase 120/240 equipment not 208volt 3 phase.
