Miller roughneck; no welder or 110v output

[~willy]

I've built a few of these back in the 80's. They are a very useful tool, especially prepping material for welding.

I extended the arm of the bottom feed valve so that it can be nudged w/ a foot or is easier to adjust while wearing gloves.

I have built a few of these and never...

Duane, thank you for the information;

I use it for setting generating speeds based on correct frequency rather than a tachometer for RPM.

Ah so.....

Thank you Duane.

Sorry that I couldn't figure it out. So just plug the Kill a watt into the welder and follow the prompts. There was so bleeping little information about the tool that I couldn't infer what it was for; looked like the primary purpose was figuring...

Thank you Duane. I wasn't able to discern what the purpose or point of the tool was from the readup at the HD links, but found at Amazon there were a lot of reviews and discussion.

It looks clean enough to me, but I saw no evidence that you were able to get a puddle started. Aluminum is a tremendous heat sink.

You'll note the max thickness that the specs call for is 3/16";

Thanks for the replies. I would never plug a computer into a portable welder. For that I'd use my windmill. : )

Seriously though, so many modern electrical appliances are more sensitive to volts and amps than the old 60's technology. I've fried a few pieces running off of the old "big...

I would go with Bob's answer if it was a joining process (welding or brazing).

Often exhaust cast iron has been affected by the heat of exhaust and is often far less weldable. Quite often the filler metal will not wet out and bond to the parent metal.

If you could clamp it...

I've updated this thread a few times, as much for my own benefit as any.

I now have the unit working pretty well.

My next question i have not been able to ascertain in checking around...... regarding the 115V power output......

This is a Roughneck 1e 3500 watt...

Many years ago I was given what I much later determined must have been magnesium frame concrete forms. I was early 20 something and after cleaning them I was able to TIG weld many of the cracked units using aluminum filler. Keep in mind the cracks had concrete in them and cleaning was never 100%;...

I'm pessimistic you will get a good result.

There are a lot of reasons; dissimilar metals, cast iron will generally have a large heat affected zone, the weld maybe in a stress area, subjected to heat and extreme cold (depending on where you live or drive), dynamic stresses and vibration....

Update
----------------------
Sorry; the unit is outside so I don't have to deal w/ fumes; remember I have been dealing with fuel issues and also don't want to run the unit inside. It stopped raining and so i went out and cleaned the (commutator?) rings. I also did a half-hearted spray...

[~willy]

I've welded on my share of tanks successfully; even a fuel tanker.

I have to agree that giving info on this may be a little irresponsible to an amateur.

As an addition to this thread I thought that I would add this little link. Some of you might think; here, but by the grace...

[~willy]

Howdy guys. My first post. I've been searching the net but haven't quite found the answer and figured I would just join, ask and see if i can get the unit to put out. : )

I used to weld a lot more than I have lately. When a Miller Roughneck (1a ser #HE748281) came up for sale I decided...
