I've used compressors of all types over the years, but never really paid attention to what any of them were. When we moved in, a housewarming/bday gift was an oilless 17 gallon Craftsman compressor. It's done fine for light stuff, and will give great service rotating tires, or cracking a rusted bolt etc. When it comes to running a cutoff tool or die grinder, it runs continuously and canot keep up.
I want to tinker with my own small painting and blasting setup...but compressor prices are steep. Low and behold, by buddy had an old one of his grandfather's he wanted out of the garage. It doesn't work so he said, and for free, I figured I couldn't lose. Turns out, he simply doesn't have an outlet for it. Neither do I.
What are your thoughts on this old girl? I'm going to test it out off my genny, and then run 220 to the garage, which I'd like to have for a welder anyway. I know nothin bout compressors...yet. Hoping it works and don't leak.

I just thought I would chime in on this one...
I am an electrician and my company also has an electric motor Sales/Service shop. The motor is definitely 230V only. I would put it on 20A breaker for sure (Breakers only continuously handle around 80% of their rating.) No less than #12 wire, #10 if the outlet is a long distance from the breaker box. |

This particular welder is a 310 amp AC/DC Tig/stick that also has a water cooling system that runs on the same circuit. |

Normal household voltage in the states is 110-120 Volt single phase. Higher load devices (oven, clothing dryer, well pump, etc.) typically use two 110 circuits combined for 220 Volt.
Basic industrial use is 208 Vac 3-phase, 240 Vac 3-phase, or 480 Vac 3-phase. |

Gentlemen, sorry to hijack the thread but I must be missing something. Here in Australia we have 240 volt and pretty much everything the bloke at home could want runs off 10amp. My compressor is 12cfm (from memory) and it's only 10A. My 140 Amp Fronius inverter welder is a 15 Amp unit that I run off a 10 Amp power point. Day in day out no worries. My 210 amp mig is also 10 Amp. Our next larger power choice is only available to commercial property and that's 3 phase 415 volt in amperages ranging from 10 to 32 and the rare 50amp outlet. How is it you require up to 100 Amp? |

I should have said "for a small welder". I have a few welders. My large MIG runs on a 50amp, my little flux core on a 20amp. My large TIG/stick is on a 100amp breaker. All depends on what you got! |

Well Daniel that tells me what the A. stands for on the tag I wasn't sure it was for amps or not.( A 12 ) That clears that up. you run your welder off a 20 amp circuit? I use a 50amp on mine. |

Bill, thats simply gorgeous! How I would love to have a space like that....
I was figuring on 20A....I didnt think I would need more, and the oddball Hart-lock plug on this thing is rated to 15A. Im going to switch that over to a more common plug. Took me a bit of investigating to even find out what it was. It's a twist lock style, but more compact than Im used to seeing. |

I have a 200 amp service in my garage nothing smaller than a 20 amp breaker in the service panel. My best friend and buddy and I did the wiring. He is a certified electrician. We also built the garage. Took us 3 years in our spare time we had to work in between time  . I was looking at the picture of the information on your motor and I don't see any amperage rating so I would not go any lower than 20 amps for a breaker. # 12 wire.

Oh, I'd love a larger unit...with my current accomodations I just don't have the room, or a real need for a bigger setup. Someday, when we get the polebarn etc, maybe =] (My wife is going to need a change of britches when she sees my plan to convert 'her' small space to a temporary paint booth)
I would LOVE to have a unit to get a start in welding too, and with the free compressor, I don't mind running the 220. I think it will be nice to have out in the garage. I'm looking at about 9' of wire, so I shouldn't be in too bad of shape when it hits the wallet. $60, $70? I have been researching this motor, and I'm not seeing where it has the option to rework to run off 110, otherwise, that could be an option. Motors themselves are real pricey. The buddy who gave it to me is running a similar, 2hp compressor on a 15A/110 line and it trips over and over. He's in the process of looking at running a new dedicated line too.
I'm picking up lots of info...good stuff to learn, thanks! |

Plus, looking at the price of decent 110 and dual stage motors, I'd rather sink the money into copper and the right outlet and breaker.
How much is it going to cost to wire it for 220 volt?Its your pocket book. I was not suggesting that you run it on 110 volt forever. I was thinking you could look at the one you have and see if it can be reversed to run on 110 until you can get the 220 wired up, if that's what you are going to do. Yes it will run better on 220 no doubt about it. I have a small compressor like the one you were given that I use outside of the garage, it runs just fine off 110 volts. I also use it with my portable generator. Its good for running a nailer or airing up tires in the yard ect. Maybe you could sell that one and put the money towards a larger compressor because I know your going to want one. I know I did. |

You want to look at CFM output. I have a 5hp compressor 60 gal tank, running off 220 volts with a cfm output of 18 cfm at 120psi. This will run my paint guns and air tools reasonably well. There are times when I have to leave it catch up like when I'm painting a car or large object. I should change the tip size in the paint gun so it will use less air. Better yet a hvlp paint gun setup would solve the problem. Bottom line is lots of CFM output the more the better. Look at the motor see if you can rewire it for 220 volts. Some motors can be run off 110 or 220 volts look at the wiring diagram on the label or tag. |

it might be easier to just find a comparable 3hp motor in a 110v model and swap it out
but 220v is always nice to have for the welder you havent bought yet
