i'm wiring some 10gage out to the garage to a receptical, but instead of wiring up another extension, i'm going to leave it lose so i can move it around the garage. Anyone seen any 220v receptical boxes ment for the garage floor? I mean, other than the your standard mangled steel box.
Reply:Well they do make a 6-50R (receptacle) that is a receptacle for a cord, not a wall mount. Not easy to find but they are out there. Last one I saw was at Tractor Supply over under the welding section.If you insist on doing this you should run your #10 to a wall mount box then hardwired out of that box to a SO cord as an extension cord with the 6-50R on the end of it. Make sure your so cord is securely retained in/at the box you use for splicing. SO cord won't exactly be cheap in the world of wire but it is the way to go in the shop environment. I'm assuming your welder comes with a 6-50P (plug). If not then you'll need to match what it does come with.
Reply:if by 6-50R you mean (2 vertical prongs(one short/one long) and a post on middle top) then yea. I'll look for the cord recepticle next time to tsc. thanks. And the SO cord, that wouldn't happen to be underground grade would it? Your right, i'll deffinately go to a junction box from the main to the garage and hardwire a long(10ft or so) lead from there.hey Sandy, you wouldn't have a recommendation on breaker size would you? the receptical says its a 50A, but for a 175A mig, is that sufficient? thanks for the help.
Reply:With #10 gauge wire , do NOT use bigger than a 30 amp breaker . that is probably suitable for your welder . if not , then you will need larger wire . #8 for 40 amps ; #6 for 50 amps , etc. i use a 50 amp service for my Lincold sp 250 mig machine , & a 100 amp service for my miller 250 amp dial arc H F tig machine . I had to replace the breaker box on my house ( from 100 amp to 200 amp service . ) expense , expense , expense - everything cost up the ying yang nowadays .
Reply:thanks Roy H. the recepticle Lincoln calls for is a 50A. i think the box calls the 175 a 50Amp machine as well, so i'll need 6gage for everything. i recently upgraded my house with a 200A service, so i've got plenty of room. thanks again.
Reply:Roy called it right. Licolns 175's use 20 amps input at maximum output, which is rare and not continuous duty. Remember, most ratings we are used to are for continuous duty circuits. A 30 amp breaker is plenty for lincolns 175 class machines. The plugs on all these small to medium class machines is a 50 amp just for standardization and ease of installation and portability. That doesn't mean you need a 50 amp breaker tho. 10 awg with a 30 will be perfect.Licoln can be a little flaky on their installation recommendations. They'll say anything from a 50 amp breaker to a slow blow 40 amp fuse. They could do a little better in that department. SO (Service grade O) cord is the black stuff you see. The flat black rubberized cord, not the shiny black. It's a utility grade that is UV, oil, and water resistant and somewhat impact resistant. Good stuff. The price varies a lot but if you only need 10 or 15 feet it won't be a killer. Three wire 10 awg will run from 93 cents a foot to a $1.60 a foot from store to store. I've seen some specialty shops try and gouge people 3 and 4 bucks a foot for it just because they can and some people believe that anything from a specialty store should be high priced. If they try and do that to you reach over the counter and smack 'em upside the head ..Edit to say by "flat black" I don't mean "flat cord". I mean the "not shiny" black..

Reply:Having just purchased and SP175, I'm in the process of installing a 200 amp panel in my house to run the thing. Eventually will need the whole of the service swapped over but it won't be to bad for now. This old house had every thing running on 4 breakers at one time.In any event a couple of things you should know. First Lincoln suggests 40 amp slow blow fuses, that is a bit above their listed current range of 23 amps. So as a base line lets say we are going to see surges above the 23 amps, thus Lincolns suggested fusing. There is also the issue of duty cycle, a machine rated for 20 amps will not run reliably on a 20 amp branch circuit full out.So the first thing that I would do is to wire the fixed wiring at a minimal to handle 40 amps. Better yet is to wire the circuit for 50 amps KEEPING the breaker at the reccomended 40 amp size. You can run wire that is larger than what is needed for the branch circuit but You must NEVER go the opposite way. The breakers purpose is to protect the wiring, so as Lincoln wants a branch circuit with overcurrent protection set at 40 amps then the wire must be sized for that as minimum. This puts us into the range of #6 wire for reasonable length runs and should control voltage drops very nicely. It also means that the wiring is in place if you should happen to want to up grade to a machine needing a full 50 amps out of the socket. Mount a corresponding outlet in your garage and then use a properly sized extension from there.Running this size wire is no fun as some sort of race way will have to be used. The other option is a multi conductor cable but expect to need help.In a nut shell if you are going to wire in a branch circuit for this it must be rated for 40 amps minimum. This to correspond to Lincolns reccomended fuseing.ThanksDave
Reply:If you check into the code i think you will find that the wire size can be derated for welding cicuits only. The reason for this is duty cycle of the welder.

Reply:I'd have to run down cellar to review my copy of the code but I thought at one time that was feeders for hardwired welders. Even if it is not, I would have a very hardtime running a 30 or 40 amp branch circuit and not minimally meeting code for such circuits. Especially when the circuits would be feeding what are in effect general purpose outlets. Not only would I be concerned about liability, but I can also remember back to the days when things in my fathers shop where often ran off one outlet. If you wanted to run the air compressor you had to unplug the table saw. I just don't think it is advisable to assume that an outlet will always have a welder plugged into it. In fact in this day and age there is a real good chance that it won't have just a welder plugged into it. Just think about how many guys have a their eye on a Plasma torch here.It is very important to get the branch circuit over current ratings right for the wire sized used. Personally I just got a little 220 Volt MIG (SP175) and have every intention of following Lincolns advice for overload sizing. Further the wiring will be sized for that overload device or larger.ThanksDave Originally Posted by Tailshaft56If you check into the code i think you will find that the wire size can be derated for welding cicuits only.

Reply:Neither do I! That however doesn't keep me from adding to my kingdom (yes it is catching).By the way I've learned the hard way that it is better to do without a garage rather than to build one you won't be happy with.Dave Originally Posted by zapsteri dont have a garage ...zap!
Reply:I believe it's for dedicated welder outlet. I think a plasma would be ok. Anything else would be no no. Welders generaly have a different plug than machine tools and woodworking stuff. It really won't save a lot of money unless it's a long run and then I think you wouldn't want to downsize.DennisThermal Arc 185-TSWMillermatic Challenger 172VictorO/AAtlas Craftsman 12 by 24 LatheEsab PCM-875Wholesalem Tool Mill-Drill |
