You have two electrodes mad out of carbon, and then you cause a sparc to arc over from one electrode to the other. By maintaining this arcing you get light.

Can carbon monoxide be used in welding instead of Argon?
Carbon Dioxide iswidely used for MIG welding but I never heard of carbon monoxide and it is definitely not used in the industry as shielding gas. The purpose of the shielding gas is not just shielding the weld pool but offer arc stability with an adequate ionization potential. The heat and electrical conducctivity of the gas at the arc temperature are a huge factor as well.
Can you melt gold with a torch?
If your torch reaches 1064C you can, but if the torch can't get that hot then you cannot.
What material can a be torch made out of?
a torch can be made from wood and plastic
How does the carbon cycle work with the nitrogen cycle?
Both of them are different, so both cycles work together. The carbon cycle lets out carbon dioxide and it then transfers it into the trees. The trees get the nitrogen and the cycle starts again.
How could a torch show if you have a colloid or a solution?
if you shine the torch through it
Where can a person buy carbons for a vintage twin-carbon arc torch?
Any welding supply carries or can order for you, air arc carbon rods. They are the same that is used for air carbon arc gouging. Carbons are produced in two shapes, flat and round and various sizes. You would want the round ones.
In MIG welding what are the polarities of the torch and the work-piece and what is the fundamental reason for this?
MIG welding works only with reversed polarity, DC+, + at the torch. The reason is mostly the stability of the arc. Using DC- will result in a very unstable arc with lots of spatter.
What is a carbon arc lamp?
An arc lamp is a lamp that produces light by an electric arc. The carbon arc light, which consists of an arc between carbon electrodes in air, invented by Humphry Davy in the early 1800s, was the first practical electric light.
Why doesn't your torch work?
my torch does work though...
How much carbon dioxide does the Olympic torch emit?
5500 tons of carbon dioxcide
How does a torch switch work?
It provides the light in the torch
The electrode holder used for shielded metal-arc welding may not be used carbon arc welding?
Any electrode holder that will accommodate the size of rod can be used. Twin Carbon Arc Welding requires a specific holder. Air Carbon Arc Gouging requires a special holder that also supplies a stream of air.
Can 2010 Winter Olympic torch runners keep their torch?
Yes they can. And to make sure they are authentic they are told not to wipe the soot off the torch. The carbon stain authenticates the fact the torch was lit and used in the relay.
What is Gouging torch in welding?
There are two types of gouging. First is with oxy-fuel. A special tip is used in the cutting torch that lets you direct the flame almost parallel to the work. A low pressure setting on the oxygen is directed thru the center of the tip. As the preheat flames melt the surface the operater depresses the cutting lever and the oxygen combines with the molten metal and is blown out creating a gouge as you proceed across the metal. The second requires a special torch and electrodes and is called carbon air arc gouging. High amperage settings allow you to establish an arc between the copper coated carbon electrodes and the metal. This melts the metal while a continous flow of high pressure air blows the molten metal out and a gouge is created as you move across the surface. In both instances the slower you move across the metal the deeper the gouge.
Does anybody still use carbon rods for Photography?
Carbon arc lighting died out decades ago. The only carbon arc lamps still used today are restored World War II searchlights used for promotional purposes.
How does a wind-up torch work?
no
Will a torch work on the moon?
Yes
