No, there is no MiG-22. The MiG (Mikoyan-Gurevich) series of fighter jets produced by the Soviet Union and later Russia includes aircraft such as the MiG-15, MiG-21, MiG-29, and others, but there is no MiG-22 in the series. The closest aircraft to a MiG-22 would be the MiG-23, which was a variable-geometry fighter jet developed in the 1960s. **

Yes, the MiG-21 can be visited in Germany. The German Museum of Technology in Berlin has a MiG-21 on display as part of its extensive aviation collection. Visitors can see the aircraft up close and learn about its history and significance in the context of Cold War-era aviation. The museum provides a unique opportunity to explore the MiG-21 and other iconic aircraft from various periods of aviation history. **

The "bis" in MiG-15bis stands for "second" in Russian. It is used to denote an upgraded or second version of the original MiG-15 aircraft. The MiG-15bis featured improvements over the original MiG-15, such as a more powerful engine and enhanced armament capabilities. **

It is generally not recommended to soft solder aluminum due to its high heat conductivity and the difficulty in achieving a strong bond. MIG welding is a more suitable method for joining aluminum as it provides a stronger and more durable bond. MIG welding allows for better control of the heat input and the use of filler material, resulting in a more reliable and structurally sound weld. **

The electricity consumption of a MIG welding machine can vary depending on the specific model and settings used. On average, a MIG welding machine can consume anywhere from 100 to 600 amps of electricity per hour. It is important to refer to the manufacturer's specifications and guidelines to determine the exact electricity consumption of a particular MIG welding machine. **

The German Air Force no longer has MiG-29s because they were acquired from East Germany after reunification in 1990. The MiG-29s were seen as outdated and expensive to maintain, and the decision was made to retire them from service. Additionally, the German Air Force shifted its focus towards modernizing its fleet with more advanced and capable aircraft, leading to the retirement of the MiG-29s. **

To set up a MIG/MAG welding machine, start by selecting the appropriate wire and gas for the material you will be welding. Then, insert the wire spool and feed it through the wire feeding system, making sure it is properly aligned. Next, adjust the welding voltage and wire feed speed according to the material thickness and welding position. Finally, connect the gas cylinder to the machine and set the appropriate gas flow rate. Once everything is set up, you can begin welding by pulling the trigger on the welding gun. It is important to refer to the specific machine's manual for detailed instructions on setting up the MIG/MAG welding machine. **

Aluminum is typically welded using direct current electrode positive (DCEP) in the MIG (Metal Inert Gas) welding process. This type of current allows for better penetration and heat distribution when welding aluminum, resulting in a stronger and more stable weld. DCEP is commonly used for welding non-ferrous metals like aluminum due to its ability to provide a stable arc and good weld quality. **
