You must know that the argon arc welding machine is a kind of high-tech welding application equipment, which performs this series of spot welding steps in the form of high pressure. When I was studying physics in junior high school, I was exposed to the knowledge of electricity. Among them, the magnitude of current is also the most concerned point of electricity, because the magnitude of current will affect the normal operation and operation of various devices. Any kind of equipment has a certain voltage range and current range, and the size of the power is also determined according to the range of the two values. Therefore, the current size of the argon arc welding machine will affect the welding effect to a certain extent. DC Welding Machine The current and voltage of the AC arc change their direction every half cycle, and the arc discharge conditions change periodically, so it has an important impact on the stability of the arc and the work of the welding power source. The case is p

The difference between AC argon arc welding machine and DC argon arc welding machine: 1. DC argon arc welding, that is, using argon as the shielding gas under the direct current positive connection method, with the help of the arc between the electrode and the weldment under certain requirements (welding current), heating and melting the base material, and adding the welding wire when the welding wire It also melts into the molten pool and cools the weld formed. 2. Pulse argon arc welding, in addition to the specifications of DC argon arc welding, it can also independently adjust the peak current, base current, pulse width, pulse period or frequency and other specifications. It has advantages compared with DC argon arc welding.  DC TIG Welding Machines As follows: (1) Increase the aspect ratio of the weld, and increase the penetration width to 2:1 when welding stainless steel (2) To prevent burn-through, in thin plate welding or thick plate bottom welding, the peak current passing tim

Principle: Electric welding equipment uses electric energy to melt the solder and the material to be welded on the welding rod by heating and pressing, that is, the high temperature arc generated when the positive and negative poles are short-circuited instantaneously. With the help of the combination and diffusion of metal atoms, two or two A devices where the weldments above the pieces are firmly connected together. It is specifically composed of a welding rod, an electric welding machine, an electric welding clamp, a grounding clamp and a connecting wire. According to the type of output power, it can be divided into two types, one is AC welding machine and the other is DC welding machine. AC Welding Machine The structure of the electric welding machine is very simple, it is a high-power transformer. They use the principle of inductance, the inductance will produce huge voltage changes when it is switched on and off, and the high voltage arc generated when the positive and negative
