  • Size Matters???

    Looking for some advice on an extension cord for my welder. I have just bought a Hobart 187 and would like to rig me up an extension cord for better mobility around the shop.
    I would like to make a 15' - 20' extension cord; what gauge wire do I need?

    Thanks
    Bill

    Bigger is better. I run my HH187 with a 20' 10 AWG on a 30 amp breaker with no problems at all.

        You can buy a 25' extension cord for round $50. Just GOOGLE "welding extension cord"

            You would be fine using 12g,but if you already have 10g use it, don't waste the money on anything thicker than 10. 12/3 300V sjoow is about $. 80/ft where as 10/3 300V sjoow is about $1.70/ft, around here any way.

              I agree with Mengineer. While 14 is legal in some cases it needs to have a max breaker of 30, a 12 or larger cord can be use on circuits to 50A and personally think these little machines need all the help they can get, I am always trying to squeeze the last drop out of them anyway. The main advantage of a 10 is it may be suitable for other machines also.

                Thanks

                I have several pieces of 10/3 and one of them is 21, so all my cost will be for the plug and outlet.
                Thanks for the advice!

                  I don't know what's available by you but instead of using the normal plastic case 6-50r wall mount, tractor supply actually has a Hobart plug end 6-50r for $20. It's about $8 more than the wall mount at lowes, but it works better for an extension.

                    At that load the 187 wont even recognize its on a cord, it would work at a hundred feet or more.
