Welding equipment

Arc welding is the use of high temperature positive and negative poles in an instant short circuit to melt the solder and welding materials to be welded on, so touched was a combination of purposes. Its structure is very simple, it is a power transformer. Welding generally based on the output power can be divided into two types, one is the AC power supply, one is current. They use the principle of inductance, inductance in the on and off voltage change will have a huge, positive and negative poles of a high-pressure arc short circuit in an instant to melt the solder on welding, to enable them to achieve the purpose of combining atoms
