Lincoln SP-175Plus

Alright dougie, I went to HD today to buy the stuff to make the extension, but I got confused again.

I'm thinking what I can do is use one of those dryer cords with the 4 wires and run that to a 3 wire receptacle in the garage. Dryer cords come with 6', its about 3.5' to the wall. Then, can I connect the 4 wire to the 3 wire plug like we saw at HD? Then I get another 3 wire plug like we looked at, run some 10/3 extension cord material and either splice it in with the existing cord (could use plug from welder) or find one of those black boxes and just plug the welder into that. I still couldnt find one of those at HD, so might have to run to lowes, or do they not make them like what I need for some reason? Otherwise, I could just use a wall mount plug and just build a little tin foil 16/18 ga box for it.

To summarize:
Drier plug from 220 outlet in laundry room to:
3 wire receptacle in garage wall to:
3 wire plug to:
10/3 cord to:
3 wire receptacle to:
welder

Thought again about just having an extension cord, but it wouldnt fit through the door seal with the door closed unless I put a notch in the door jam, which isn't out of the question.

go to praxair, or airgas, I know there is a praxair on airgass and they will be able to hook you up with the right stuff

fubar that, we'll get raped!

I'll call central electric supply tommorow and check prices. I know they're cheaper than dealers electric. How long of a cord did you want again? I guess I should really just come to your house and check out the situation.

I'm thinking like maybe 35~40 ft so I can run clear to the end of the driveway on a straight shot + the 6' power cord on the welder. If I run straight from the dryer outlet, probably add 8' to that.

So...

how do I go from this

Still not sure if I can just drop one of the wires from the dryer plug and add in the 12/3 and run the 3 prong plug on the other end.

I'm not sure what you're wanting. Are you wanting to extend the dryer circuit into the garage and put a 50 amp outlet in the garage? Or are you wanting to plug that 50 amp plug into that 30 outlet with an adapter? Or do you just want to change that outlet to a 50 amp, or do you want to keep that outlet and put a 50 amp besides it?

I'm trying to make an extension cord for the welder. Want a plug for the dryer receptacle and a receptacle for the welder plug. Don't know about the different types of receptacles/plugs.

So, you just want to put an outlet for the welder right next to the outlet that's there, and then you will use an extension cord from that outlet to the welder? Then what you need to do is put an outlet for the welder next to the dryer outlet, and hook the wires up. It would look best to put the new outlet in the wall to match the existing one, but it'd be easier to just use a plug/box combo that can be screwed to the wall. Make sure you put the second outlet between the same 2 studs as the first so you don't have to run wires through a stud. You do not disconnect any wires from the dryer plug. You should have someone come show you how to hook up the wires. It's real simple but you don't want to **** it up.

No, I want to plug into that outlet with an extension cord for my welder. Can I not do that?

Yea you can do that. Don't see what you're asking then. You know what you want, go buy the ends that match what you need.

Here's the deal... You have two 120V legs going into your house. Some 120V circuits branch off of one leg and some off of the other. your 240V circuits for the dryer, heater, etc come from both legs. AC powered devices do not need a ground to operate. The ground is for safety. They do, however, need a neutral line. Sometimes when a breaker box doesn't have a ground, people just hook the ground up to the neutral bus. If your dryer has a three prong plug, then it contains two hots and one neutral. If it has four, then it also has a ground. If your welder has three, then it's the same thing. If it has four, then it has a ground. If the outlet is three pronged and the welder is four pronged, then you just don't hook up the ground and it will still work. Again, the ground wire is only used when something shorts. It provides the path of least resistance. You may need to go to Central Electric in Bryan with sketches of the plugs if you can't bring them in. They will have the correct male and female ends for you and they will also have the insulated 3 or 4 conductor wire for you. If it is four wire, it should have black, white, red and green. If it is three conductor, it should have red, black, and white or two blacks. BLACK IS HOT!!!!! BLACK IS NOT GROUND!!!! White is neutral. Do not reverse them. You can also just make the cord for your welder longer and then you'd only have to buy the male end and the plug that fits into your dryer outlet.

Got it?

In edit: It looks as though your dryer outlet is 4 conductor and your welder is three conductor. The 90 degree prong is the ground. You could just buy some three conductor wire and don't use the ground. If I were you I would just buy a plug that fits that outlet and wire it all the way back to the welder. If you do it this way, you could include a ground wire by getting a 4 conductor wire and connecting the ground to any part of the frame of the welder..

So I can just use the 4 prong (50 amp) plug and just not use the ground? Run this with 10 or 12/3 to a receptacle for the 3 prong (20 amp) plug on the welder?

Extending the cord for the welder was an option, but I think I want to keep that "stock" just in case anything ever happens.

12 gauge is good for 25 amps and should be fine. It would be cheaper to make a new cord for the welder. You could always hang on to the pigtail and return it to stock condition if necessary.

Me and dougie got everything finished. Gracias doug.

Finished opening/setting up the welder and laid a little bead on some piece of metal I bought at TSC for $1. Remembered I shouldnt be welding on wood after I set my workbench on fire and put it out with my spit bottle.

I'll be scavenging at a buddies ranch on saturday to find free metal for a table, and that will be my first project.

yay for me
