The cost of the welding machine is 2-3 times more than the rectifier and in 5- 6- transformer. The most popular and often used, of course, is considered a welding machine, or as it is called the scientific, inverter. You are wondering why you should give preference to this type of tool? Everything is very simple, because it is small and very light, it is just to use it, and it is very productive and much more. Let’s look at the strengths and weaknesses of the inverter to technological advantages can be attributed: — stability when ignition of an arc — you can brew various metals that are difficult to combine — the seam turns out to be of excellent quality — with its help the most difficult work will seem light — you can work using different types of current and various brands of electrodes — and much more.
