Oh baby, where you been all my life?

So any Ideas as to wether this is an AC or DC?????

Definitely an AC welder.

Plus, in a welder that old it would have a switch to choose between AC and DC. The newer inverter welders can come in DC only but they are fairly recent.

If AC works for you than that is what you need. No need to mess with success.

The guy who owns a large welding and steel shop nearby is always telling me to go with 7014, says they're "smooth as butter" and gives me a small handful of rods. I was not impressed, been having much better results with 7018 lately, especially since I got my DC machine.

usually in these welding threads (on this site and others) I am one of only a very few who even suggest 7014. And like I said, we usually take a beating for it too.

I won't comment on a subject I know nothing about. Ever since joining these forums I've read about people using 7014, so I kind of felt left out of the conversation. I thought, I'll never know until I try it. I' am impressed with how easy it is to run, especially on fillets. I can see where there is a difference in it from 7018, with 7014 you have to use more rod angle, and force the slag to stay behind the puddle, like 6013. Where as 7018 you can run a steeper angle, and not have to worry about the slag. It is very nice not to have to worry about a rod oven and still get pretty much the same strength as 7018. For us hobby / weekend warrior types bending a weld 170-degrees is pretty much all we'll ever need a weld to do.

Always read about people using 7014, I've never even seen it much less use it. So I picked up some yesterday at the local welding supply, gave it a try this morning. OMG this stuff is child's play! Kind of an all position jet rod, (7024).
First two pictures are flat, the 3rd picture is vertical up. The camera doesn't do the vertical up justice, it looks better in person.

I've never used 7014 either but you mentioning 7024 "jet rod" brings back memories. OJT welding job in highschool. I worked for a company who fabricated oil storage tanks. We'd lay out the sheets of 3/16" steel and weld them up with 6010. Then we'd pick up the massive "wall" of steel sheets with hoists and turn them over. Then we'd weld that side with 7024 to make the seems look nice and smooth. This would end up being the outside of the tank and gave it a good look, like a mig was used. This company didn't even own a mig welder we commonly used the old Lincoln "torpedo" welders. Running 7024 you could set your amps and just lay it in the groove and go. That flux would just rise up and curl right off the bead. As far as running 7014 and 7024 how's it compare? Personally, all 6013 does is frustrate me!

Sounds like one of the older AC units originally made by Forney to me. If it does not have any ports marked DC then it is an AC only welder. Hey all this talk of 7014 got to me, at noon today I bought a pound of 7014 3/32 and a pound of 7014 1/8 just to try out.

7014 isn't near as fast as 7024, but the slag, puddle, and completed weld looks similar to 7024.

What's that saying? Oh yeah curiosity got the cat!

No switch to choose betwee AC/DC.

The only swich is the Main On/OFF at the top.

One thing kinda puzzling though, if it were an AC only machine, why would it matter which hole the singer and which the ground is plugged into??? Because they ARE different sizes.

I can remember which one is which, But one has the A and B option, And the other has about 10 or 12 different holes to choose from. Beside each of those holes is two amperage ratings, one for A, and one for B.

I'll have to see if I can find some pics. The welder isnt at my house currently:confused2:

Maybe these pics will help. Sorry but they are the best ones I can find in my inventory. But look close any you can make out the welder.

And it does appear that it only has 8 holes for the amperage setting PLUS the AB. So a total of 16 different options.

Look at the attachment that I posted in posting #18. Since you are already familiar with several other rod types this chart will quickly tell you how 7014 compares in relative aspects to other rods that you are already familiar with.

On AC there is no such thing as polarity since polarity is autimatically alternating back and forth at 60 hertz. My guess is the original maunfacturer made the plug on the ground wire different to idiot proof it so to speak. It keeps someone from accidentally plugging the ground clamp into a hot tap right right next to a stinger hot tap. This would not weld and might even damage tranformer if someone accidentally did this. With AC you theoretically could move your stinger to end of the wire with the unique tap and move the ground clamp to the wire that changes tap ports for amp selection and it will not alter welding performance.
