Question:

The difference and characteristics of AC arc welding machine and DC arc welding machine

What are the biggest differences between DC and arc welding machines? What characteristics do they have? They are good at welding what kind of metal materials

Answer:

Direct current welding sounds like running water. Of course, the welding quality is much better.Communication is like water dripping, so it's different.You look at the difference between the two kinds of electricity. I believe you'll find the answer you want.
Inverter DC argon arc welding machine is a non welding gas shielded welding machine. It uses argon as protective gas and tungsten needle as electrode welding machine. It mainly welds stainless steel, copper, magnesium and other insoluble metals. Inverter DC arc welding machine, welding machine DC welding by manual welding machine, it is not an ordinary DC welding machine AC arc welding machine. The price is more expensive.
Alternating current welding machine: it is a special step-down transformer which is produced by alternating current through the welding machine, and then it is welded with low voltage and high current power. The utility model has the advantages of simple structure, convenient maintenance, no magnetic deviation when welding, and wide application. Use ordinary electrode, stainless steel electrode, cast iron welding rod, power welding machine, can barely use 506 welding rod. The base metal that can be welded is also extensive (only gold, silver, copper, tin and other special materials can not be welded)Direct current welding machine: the electric energy can be welded by alternating current through rectifier to dc. The utility model has the advantages of small size and light weight. Its structure is a little complicated, and the maintenance is difficult. But its performance can replace the AC welder completely, and the application is more extensive. Both special materials and special welding electrodes can be welded.I spent 17 years as a welder, hope I can help you.
