Introduction: MonoCarbon Arc Torch

NOTE: THIS DEVICE HAS BEEN DISMANTLED IN DECEMBER 2010, TO MAKE THIS OTHER, THAT IS BETTER.

This torch is inspired in the work of Phil B:

https://www.instructables.com/id/Make_a_carbon_arc_torch_for_your_220_volt_stick_we/

I wanted to do something different (sorry, I'm so).

I thought: if two carbon electrodes forms arch, why not try with only one?

Step 1: What Is Needed

A piece of thick wire. I bought a 60 Amps, 1 meter. It can be shorter.

A spring clip, in proportion to the cable.

A piece of wood 1 x 1 inch, to make the handle.

A screw with two washers, a nut and a "butterfly nut"

A carbon electrode. I used that of a D size, 1.5V carbon battery.

Step 2: Beginning

Make a hole to the spring clip for the screw, pass it and secure it with the nut. The head of the screw must be inside a spring clip.

Step 3: Continuing...

Step 4: ...and Finishing

The other end of the cable must be soaked with tin, in this way it don't will disassemble whit the use.

This end of the cable must enter in the electrode-holder clamp.

Step 5: Now, Lets Try It

It works!!

But if one is clumsy using metal electrodes, remains clumsy with carbon electrode ("the monkey, though silk dress, monkey is.").

Step 6: Epilogue

The thing works, but I must learn to use it.

I wonder if it will be easier to learn welding with normal electrodes.

oh, sorry, there is a company in the US called Harbor Freight tools, they sell all the cheap welding equipment.

oh, lo siento, hay una empresa en los estados unidos. llama herramientas puerto de carga, se vende todo el equipo de soldadura barata.

Now I understand. I live in Argentina. My welder is the cheapest of the market, but it is good for me, I am not a professional.

Oh yeah, I hear you. One of my welders is 3 times as old as I am and the other is the cheapest on the market. They are both perfect for what I will ever need.

The two men who taught me most of my welding skills(as limited as they are) both espoused learning stick welding through the use of coat hangers. The theory goes... If you can weld with coat hanger wire, you're welding will only improve when using "real rods" AND you'll always be able to make your own rods for ugly-but-works welding. I THINK your overheating issue is probably related to that HUGE carbon od you're using, and the teenietiny machine you're using it with. Also, consider trying a blacksmithing trick. Get some Borax(laundry powder isle) and pile that on where you're gonna be welding. Makes a cheap, effective flux. When smithing, it's put on just before the final welding heat, and used to flux the welding joint.

Learning to stick weld with a coat hanger would be a very interesting experience. I understand early electrical welding used wire electrodes wrapped in paper in place of the flux coatings we know today. The current was also DC.

Hello, Phil B. It's amazing that idea, to wrap the wire with paper... I thought those things were occurrences only of countries like mine ;) Yesterday I made an airtight container to keep the electrodes, because I learned that the humidity makes it more difficult to get the arc and to make a good weld. I used a PVC pipe, the mouth of a bottle of soda (termocontractable PET) and a silicone rubber stopper for the bottom.

Rimar, I made a similar airtight container for my welding rods from some PVC plastic pipe and a screw-in pipe plug (also plastic). But, we live in a very dry climate here in the State of Idaho. Sometimes I forget to screw the cap back onto it. Some people make a small cabinet for their electrodes, even those that have absorbed humidity. A single incandescent light bulb inside the cabinet makes a heat source to drive away moisture from the electrodes. Of course, incandescent light bulbs will soon be unavailable because they are supposedly environmentally unfriendly.

i think cfl are enviromentally unfreindly because they ar thrown in the trash broken in land fill and leach mercury in the soil


the current non-political scientific understanding is...

Given the very real possibility that your electricity comes from a coal fired power plant, the numbers come out about equal.

The reduced mercury emissions from using less electricity about breaks even with a completely released CFL mercury content.

Given the increasing number of cfl recycling places now(most home depot, menards, ace hardware, some city centers, etc.) they are a slightly greener option than standard incandescent, for replacing burned out bulbs. not COST efficient, but green is usually more expensive anyhow.

our electricity comes from a hydro palnt
