What is the principle of using gas in argon arc welding machine fast?
First of all, your gas cylinder does not change too much. Whether the gas discharge welding machine controls or not depends on the size of the gas bottle. When welding, the argon gas transmission does not need to be too large, and a little bit of air will do;Check each section of the trachea is broken, the general welding torch of the two joints, as well as the middle often bent, or often foot of the place, easy to break, leak;If there is a delay gas switch, to extend the air. Had a little effect on the air.There's nothing else to look for!!!
The anti disturbance control: positive and negative at the output end of the pole indirect sensitive resistor and capacitor, the high voltage current that is equivalent to short circuit at the same time, the positive and negative terminals are connected to the inductance coil, high frequency so that the control of the high voltage current anti channeling to the two rectification circuit in the circuit in the output form end. At the same time, connected to the anode and the shell between the resistance and capacitance (PSA) can effectively prevent the high frequency current and other interference.The generation and shutdown control: and turn off are controlled by relay J high frequency high voltage current, hand switch full when the S2 is closed, then the circuit, output DC voltage of about 56 volts, it makes the relay pull in JA, the high frequency high voltage circuit, high-frequency high-voltage current output caused by arc, arc caused by the output circuit will appear large current flowing through the reactor (inductor); the freewheeling inductance, the positive terminal voltage to the reactor potential is very low (or even negative), then the relay is on a disconnected, high frequency high voltage generator to stop working complete control of high voltage and high frequency current.
It may be that the gas is too large for gas transfer. In general, the argon gas transmission does not need to be too large, and a little bit of air will do;Check each section of the trachea is broken, the general welding torch of the two joints, as well as the middle often bent, or often foot of the place, easy to break, leak;Argon arc welding, that is, tungsten inert gas arc welding, refers to the use of industrial tungsten or activated tungsten as non melting electrode, inert gas (argon) as the protection of welding methods, referred to as TIG.Argon arc welding has been widely used because of the following advantages.1 argon protection can isolate the harmful effects of oxygen, nitrogen and hydrogen on the arc and molten pool, and reduce the burning loss of alloy elements, so as to obtain compact, no spatter and high quality welded joints;2, the arc welding of argon arc welding is stable, the heat concentration, the arc column temperature is high, the welding production efficiency is high, the heat affected zone is narrow, and the weldment stress, deformation and crack tendency are small;3, argon arc welding for the arc welding, operation and observation is convenient;4, the electrode loss is small, the length of the arc is easy to maintain, welding without flux, coating layer, so easy to realize mechanization and automation;5, argon arc welding almost all metals, especially some refractory metals, easily oxidized metal, such as magnesium, titanium, molybdenum, zirconium, aluminum and other alloys;6 、 free from the welding position limit, and can be welded in all positions.
