There are many electrode holders. Including homemade ones. I developed the simplest (if you do not take into account the well-known "foot" of three hastily welded fittings), but, as practice has shown, a fairly reliable modification. I would be glad if it will appeal to other artisans. My holder is designed for the most common D3 and D4 electrodes.

The holder is simple, but...
Rice. 1. Homemade electrode holder: 1 - base; 2 - M8 bolt; 3 - power cable; 4 - contact plate; 5 - M10 bolt; 6 - nut M10; 7 - electrode; 8 - handle (winding wire PRPPM2-1,2); 9 - a layer of rubberized electrical tape

The basis of the holder is a 300 mm piece of half-inch thick-walled steel pipe. A hole with an M25 thread is made in the workpiece 8 mm from one end to clamp the stripped end of the power cable from the welding unit (using a bolt and a contact plate). A M10 nut turned into a cone is pressed into the other end (no need to weld) - under the electrode fixing bolt. The latter is inserted into a through hole with a diameter of 4 mm, pre-drilled 25 mm from this end. The handle is also decorated - by winding a coil to a coil of wire in heat-resistant insulation, fixed with a layer of rubberized electrical tape.

Air trap for insects 01.05.2024

Agriculture is one of the key sectors of the economy, and pest control is an integral part of this process. A team of scientists from the Indian Council of Agricultural Research-Central Potato Research Institute (ICAR-CPRI), Shimla, has come up with an innovative solution to this problem - a wind-powered insect air trap. This device addresses the shortcomings of traditional pest control methods by providing real-time insect population data. The trap is powered entirely by wind energy, making it an environmentally friendly solution that requires no power. Its unique design allows monitoring of both harmful and beneficial insects, providing a complete overview of the population in any agricultural area. “By assessing target pests at the right time, we can take necessary measures to control both pests and diseases,” says Kapil ... >>

The threat of space debris to the Earth's magnetic field 01.05.2024

More and more often we hear about an increase in the amount of space debris surrounding our planet. However, it is not only active satellites and spacecraft that contribute to this problem, but also debris from old missions. The growing number of satellites launched by companies like SpaceX creates not only opportunities for the development of the Internet, but also serious threats to space security. Experts are now turning their attention to the potential implications for the Earth's magnetic field. Dr. Jonathan McDowell of the Harvard-Smithsonian Center for Astrophysics emphasizes that companies are rapidly deploying satellite constellations, and the number of satellites could grow to 100 in the next decade. The rapid development of these cosmic armadas of satellites can lead to contamination of the Earth's plasma environment with dangerous debris and a threat to the stability of the magnetosphere. Metal debris from used rockets can disrupt the ionosphere and magnetosphere. Both of these systems play a key role in protecting the atmosphere and maintaining ... >>

Solidification of bulk substances 30.04.2024

There are quite a few mysteries in the world of science, and one of them is the strange behavior of bulk materials. They may behave like a solid but suddenly turn into a flowing liquid. This phenomenon has attracted the attention of many researchers, and we may finally be getting closer to solving this mystery. Imagine sand in an hourglass. It usually flows freely, but in some cases its particles begin to get stuck, turning from a liquid to a solid. This transition has important implications for many areas, from drug production to construction. Researchers from the USA have attempted to describe this phenomenon and come closer to understanding it. In the study, the scientists conducted simulations in the laboratory using data from bags of polystyrene beads. They found that the vibrations within these sets had specific frequencies, meaning that only certain types of vibrations could travel through the material. Received ... >>

Anti antibiotic 05.04.2004

When we take an antibiotic tablet, it dissolves in the small intestine and the drug is absorbed into the bloodstream.

But part of the antibiotic reaches the colon, where it destroys beneficial microorganisms. Dysbacteriosis begins, and the normal intestinal microflora has to be restored with difficulty. In addition, antibiotic residues contribute to the cultivation of microbial strains that are resistant to this drug.

The Finnish pharmaceutical company Insat has launched a "antibiotic pill". It is an enzyme packaged in a shell that dissolves only in the colon. The enzyme breaks down the so-called beta-lactam antibiotics - this is more than half of all antibiotics used. It destroys the remains of the antibiotic, which can only cause harm.
