| Post subject: | welder/high voltage question |
I got a hobart handler 187 welder for christmas but dont have one of the huge outlets it wants anywhere in the house... 
the welder can operate on standard 230V/240V household power and I have a generator that will do the 240V, but it uses a 'circular' type plug... 
Is there any sort of adapter to go from the large 3 prong to the circular connection or do i need a dedicated outlet? |

Does the amperage match up? The generator tag says 30A, what does the welder draw? |

the current range is 25 - 185 A... |

I believe that is a 240v 40A plug |

are you washing clothes? lol that is the same plug and I believe your dryer and range but you'll have to call a electrican out to your house to wire up a plug in your garage |

By amperage draw I meant what does the welder require to operate, not the weld adjustment amperage capability range. If that's a 40 amp plug on the welder, and your generator's max amperage out put is 30amps, that's why the plugs are different. I put a plug in the garage for a 220V welder and I used a 50amp plug with 3 flats. -Your plug can depend on the welder requirements. I think you'd like to try and run the welder off your generator... so subjective comment here, suppose you did change the plug to try it on your generator... If the welder pulls too hard on the generator, it's probably just going to shut itself down, right? Christmas day and the stores are of course closed, is there an adapter plug available? |

I have never seen a 3 prong to 4 prong adapter...and I work at a hardware store |

No way that Gen will run that welder. Its best to get 240 ran to where ever you will be welding. |

it will work the generator is capable of providing 22.9 amps and the welder at max load only draws 20.5 amps. just make up an adapter cable, buy the proper plugs and make the adapter |

Don't give up on an adapter. I've never heard of one either, but maybe an electrical store if the RV store hasn't got anything. |

I don't think I'd be doing much of anything > than 1/4" I'll give putting together an adapter shot - it has to be cheaper than getting a dedicated line run out to the garage. Thanks

Thanks Go to your local Lowes or Home Depot and find a dryer cord that has the right plug for your generator (or dryer outlet), then get a receiver that will except your welder plug and wire that in a box to the dryer cord. http://www.lowes.com/lowes/lkn?action=p ... yer%20cord and something like this for the box and outlet (be sure to check specs on outlet) http://www.lowes.com/lowes/lkn?action=p ... lpage=none http://www.lowes.com/lowes/lkn?action=p ... lpage=none Or instead of the box and outlet maybe something like this: http://www.lowes.com/lowes/lkn?action=p ... lpage=none http://www.lowes.com/lowes/lkn?action=p ... yer%20cord Lots of cheap options for making an adapter if you just poke around the local Lowes or Home Depot. Hope that helps. When it comes to electical, if you don't know what you are doing, find someone who does. Having an adapter made by a professional is a lot cheaper than paying for a burned down house. |

Looks easy enough to make an adapter Thanks for the info/links guys
Last question... The dryer cord has 4 wires (white, black, red, ground). The welder has 3 wires (white, black, ground). white goes with white, black with black, green with green, but where does red fit in? |

230 volt supplies have: 1 115 volt Phase A HOT wire is colored, usually black 1 115 volt Phase B HOT wire is colored, something other than black often red 1 white return wire or neutral wire - used in some equipment only if you need both 115 and 230 1 ground wire usually green that terminates in the main electrical box. (caution, should only be one ground connection or circuit breakers might not work.) http://www.make-my-own-house.com/home-electrical-wiring.html |
