  • Converting 220v to 110v?

    I'm thinking of running my Handler 125 EZ off of the 30amp clothes dryer receptacle near the garage. The reason is that the 15amp circuits in the garage are inadequate. The catch is that the 30 amp receptacle is 220v and the welder takes 110v. Would something like this converter work? http://www.parish-supply.com/electrical-converter.htm

    It seems like this would be cheap to make if the hardware store has the adapters. Any ideas?

    Buy a 220v welder and make a chord for 25 bucks then you will have alot more versatility.

      Thanks for the tip but I just purchased this welder. I think it's great but I need a more reliable power supply.

        It would probably cost you less to install a new 110v circuit that can handle your welder.

          Funny because I'm having the opposite problem. Got a 230V welder, but no 230V line.

              Maybe put in sub panel with breaker for 220V dryer and another breaker for welder. Could only run one or the other off dryer of 30 amp dryer circuit or both off 50 or 60 amp circuit supplying sub panel. Electrician will know if it needs heavier wires.

              How many wires to your dryer outlet? If it has 4 wires easy to get 110V.

                220 has two 110 power wires and a return. Just use one of the power
                wires and the return. Then you have 110V.

                  Basically NO. Its fused too high and it would need to be a 4 wire circuit, run a good cord from the washer outlet.

                    Absolutely NO.

                    230V Single Phase has two hots and a ground, not a "return." If there's not a neutral there is no safe way to achieve 115V from that circuit.

                      as constructed in the linked photo it is PERFECTLY fine to use this adaptor with a NEMA 14-30 receptacle which has a neutral.
                      it is limited to 20A on a 30A circuit (you won't pop the breaker) through two 20A breakers on the face.
                      although it comes with a NEMA 10-30 plug, (the 10-30's are not grounded) i'd be wary of how it's wired for ground.

                        I am gonna speculate and say this thing doesnt have a UL rating.

                          Thanks for the advice, I'm leaning towards running a new 20amp circuit in the garage. Hopefully it won't be too expensive.

                            Warning, Don't do what I say. I have done it but I do not recommend doing
                            so unless you have full knowledge of the hazards. Electrcity can be very dangerous.
                            If you become the ground path, you might get seriously hurt/or other. Please be
                            carefull. Keith
