I use to operate these prjectors in the 70's-80's before they were replaced by 1500 watt zenon bulbs. Only the lamp housing was changed out, the projector and film part stayed the same. The carbon rods were replaced quite often. The film was split up in about 20 minute reals usually 5 to 6. When it looked like the rod would not make it we would change it. It was a gamble if you had a short real or commercial if a small rod would make it. These ran on a AC to DC motor generator. When I came abord we used a diode unit mutch quiter but the motor-generator where still kept and we could switch over if the diode unit failed. Witch never did in around 15 years. Peerless made the projectors. These were in the bay area California USA

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.
When is l'arc de triomphe lit?
The arc has projectors coming up every night at dark, but otherwise there is no special scenery.
What is an arc lamp used to accomplish?
Arc lamps were invented in the 1940's and have many uses. Some of the uses are movie projectors and car headlamps. Arc light are also used to simulate sunlight in different types of equipment testing.
What is a carbon arc emission spectrograph?
A carbon arc emission spectrograph is a piece of scientific equipment. Emission spectography is used to measure radiation intensity, and provides information about atoms and molecules as well as chemical composition of objects.
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.
How does a Carbon Arc Torch work?
A Carbon Arc Torch works by creating an electrical arc between two carbon electrodes. When current flows between the two electrodes, it ionizes the surrounding air, creating a high-temperature arc of light and heat. This intense heat can be used for welding, cutting, or melting metals.
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.
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.
Element used in lighter flints and carbon-arc lamps?
The element used in lighter flints and carbon-arc lamps is cerium. It is a rare earth metal that creates sparks when struck against a rough surface, making it ideal for ignition systems in lighters. In carbon-arc lamps, cerium is used as part of the electrode material to create an arc of light when an electric current passes through it.
Which lamp is used for projecting pictures in the cinema hall?
carbon arc lamp
What is a carbon rod?
A carbon rod is a solid form of carbon that is often used in devices like batteries, electrolytic cells, and arc lamps. It is known for its high melting point, good electrical conductivity, and resistance to chemical corrosion.
