12. Make electrical connection in accordance with general safety regulations.

13. Disconnect the machine from the mains before changing the welding torch.

14. Verify that the power outlet is properly grounded.

Connecting the machine to the power supply

Before connecting, make sure that the voltage indicated on the rating plate of the machine corresponds to the mains voltage and frequency. The welding machine must be connected with two wires (2 phases or phase-neutral) plus a third separate wire dedicated to earth (PE). Please note that the earth connection is yellow or green.

Install on the supply cable a plug that complies with the requirements of the regulations and has the appropriate current carrying capacity, equipped with a lug for grounding.

Prepare a compliant socket equipped with a fuse or circuit breaker.

Basic safety rules when working with a welding machine

1. It is forbidden to use the device in wet, damp rooms, in the rain.

2. It is forbidden to carry out welding work with containers, containers containing flammable liquids or gases.

3. It is forbidden to work with materials that have been treated with chlorine-containing solvents, as well as near these solvents.

4. It is forbidden to use the welding machine to weld containers under pressure

5. Sufficient ventilation must be provided in the work area to remove welding fumes.

6. Be sure to use special filter glasses installed on the mask or helmet, and special clothing or gloves to protect exposed skin from the ultraviolet rays of the arc.

7. It is forbidden to operate a defective device, as well as a device that has damaged cables, insulation or loose connections.

8. Do not use the welding machine to defrost pipes.

9. Replacement of the supply cable must be carried out by qualified personnel.

10. Never open the body panels of the working device, all checks with the body of the device under voltage open can lead to a strong electric shock!

11. Do not under any circumstances weld with an open body.

12. Do not point the welding gun at yourself or touch the welding wire.

13. Do not strike or pinch the welding gun with tools.

14. Do not place the welding torch and its cable on hot objects, as this will melt the insulating materials and immediately render the welding torch unusable.

15. Whenever changing the wire spool, blow dry compressed air (max. 10 bar) through the guide tube.

16. At least once a day, check the correct assembly of the end parts of the welding torch: nozzle (nozzles), contact piece and gas diffuser.

17. Before carrying out maintenance operations and replacing parts of the welding gun, disconnect the machine from the power supply and cool down the welding gun.

18. If the hole is deformed or enlarged, replace the mouthpiece (tubular current lead).

19. Regularly clean the inside of the nozzle(s).

Artificial leather for touch emulation 15.04.2024

In a modern technology world where distance is becoming increasingly commonplace, maintaining connection and a sense of closeness is important. Recent developments in artificial skin by German scientists from Saarland University represent a new era in virtual interactions. German researchers from Saarland University have developed ultra-thin films that can transmit the sensation of touch over a distance. This cutting-edge technology provides new opportunities for virtual communication, especially for those who find themselves far from their loved ones. The ultra-thin films developed by the researchers, just 50 micrometers thick, can be integrated into textiles and worn like a second skin. These films act as sensors that recognize tactile signals from mom or dad, and as actuators that transmit these movements to the baby. Parents' touch to the fabric activates sensors that react to pressure and deform the ultra-thin film. This ... >>

The attractiveness of caring men 14.04.2024

The stereotype that women prefer "bad boys" has long been widespread. However, recent research conducted by British scientists from Monash University offers a new perspective on this issue. They looked at how women responded to men's emotional responsibility and willingness to help others. The study's findings could change our understanding of what makes men attractive to women. A study conducted by scientists from Monash University leads to new findings about men's attractiveness to women. In the experiment, women were shown photographs of men with brief stories about their behavior in various situations, including their reaction to an encounter with a homeless person. Some of the men ignored the homeless man, while others helped him, such as buying him food. A study found that men who showed empathy and kindness were more attractive to women compared to men who showed empathy and kindness. ... >>

New electronics will withstand radiation and heat 28.06.2012

Engineers from the University of Utah have developed microscopic mechanical devices (MEMS) that can withstand the most powerful radioactive radiation and heat. According to scientists, the devices they have created can control robots or computers even inside a reactor or in deep space.

Ionizing radiation quickly damages traditional electronics, so you have to use numerous redundant circuits and powerful protection, as was the case, for example, with the robots that worked at the emergency Fukushima nuclear power plant. But even the protected robots sent to monitor the damaged reactors stopped working after a few hours. The thing is that powerful ionizing radiation breaks through "extra" conductive channels in semiconductors, which disables electronics.

For the first time, scientists have managed to develop a unique technology that continues to work in the presence of even the most powerful ionizing radiation. The new devices are 25x25 micron logic elements that perform the simplest logical operations: "on" or "off". Microscopic mechanical devices can even work inside a nuclear reactor

During the experiments, new devices were immersed in the core of a university reactor for two hours, and MEMS continued to work as if nothing had happened. MEMS have not been destroyed by ionizing radiation because they do not use semiconductor channels. These are simple microscopic switches with tungsten electrodes that touch each other and make or break a circuit.

In terms of "traditional" applications, MEMS have certain drawbacks, for example, they are 1000 times slower than silicon electronics and, moreover, less durable (due to the presence of moving parts). However, when it comes to extreme operating conditions, MEMS is unmatched. So, during the experiments, microscopic mechanical devices worked for hours in a vacuum at a temperature of 277 degrees Celsius and even in the core of a 90-kW research reactor. Even the most reliable and protected silicon electronics in such conditions failed after a few minutes. Under normal conditions, MEMS worked for about 2 months, completing more than one billion cycles without failure. Currently, scientists plan to improve this figure by a million times.

The use of MEMS opens up completely new possibilities for monitoring the operation of nuclear power plants, internal combustion engines and creating probes that can penetrate the most dangerous places without requiring powerful and heavy protective systems.
