I have a speedaire air compressor 13hp/generator 115v combo and want to run a 220v welder. Do you think these would work. http://www.quick220.com/220_volt.htm

Not unless you have two independent 110 circuits, John.

Just what I was thinking.

 

[darkstar]

How will he get that? two generators?

 

[JohnB]

It may be possible to put a bigger generator on the compressor.

Does your generator have 2 110v outlets ???

 

[JohnB]

Yes it does

 

[NeTree]

Check the voltage from the hot side of one outlet to the hot side of the other. If you get 220v, your generator is split-wound, and yes... you can pull 220 from it. If you still get 110v, the generator is a single-coil type (both outlets are powered from the same coil), and no you can't.



Best bet is to just get a bigger gen head.

Regarding that 220 adapter, you can make one easy enough, just remember that your maximum allowable amperage is 1/2 at 220 than at 110.

Y I B!!! U are a fart smucker!!!

 

[NeTree]

Huh?

 

[JohnB]

Well now I'm told that the generator like the one at northern tool and grainger are 5 kva and I need at least 15 kva so it not work at all.

 

[NeTree]

WTF told you that? What's the nameplate amps at 220 on your welder?

15kVA is about 65 amps at 230 volts (single phase). I don't think your welder draws THAT much.

5.5kW is about 23 amps at 230 volts; probably adequate for most MiG and stick welding uses.

 

[Rotax Robert]

NeTree is correct. It will run most mig but probably in a stick application 3/32 rod would work best. 1/8 rod or larger would be a bit much of a pull. All the fancy pancy adapters do is combine two separate 110 circuts into one 220.

 

[Al Smith]

You could run a little bitty buz box with a 5 kva but that's about it . Like Rotax said the limit would be 3/32" fast freeze rods like 6013 or something .

You want cheap short duty welding in an emergency ? Series two 12 volt batteries togther ,no kidding . You can most likely burn 3/32" rod for about 15 minutes on a pair of fully charged batteries .Old plow boy trick

 

[NeTree]

Al, ya sure can... been there, done that. Works great in a pinch, albeit not too healthy for the batteries in the long run.

Rotax,

Dem lil 'lectrical things is a little basic cornpared to what I do all day now...



This is the program for a Siemens S7-200 PLC I'm putting together; it'll run the automatic spool changer I designed for some of the machines where I work.


Going logging the rest of the week with a buddy though, just to get the itch out.
