Q: What is the principle of using gas in argon arc welding machine fast?

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.

Q: There are several kinds of arc welding machine, argon arc welding machine and several kinds. What are their occupational hazards?

Answer: We specialize in the production of electric welding machine: this should be a detailed classification, very complicated. I'll give you a brief description of several types of fusion welding:Manual arc weldingArgon tungsten arc weldingCarbon dioxide gas shielded arc weldingsubmerged arc weldingmetal inert-gas weldingThe common characteristics of occupational hazards are:1. smoke and harmful gases produced by welding2. arc damage to human skin3. electromagnetic field harm to human body4. noise effects on hearing, etc..

Q: Have not used reallink argon arc welder predecessors? Would like to ask a few questions? How about the quality? OK? What is the delay time of gas? There is no fake? How much is the general price?

300A below (TIG-180, TIG-200, TIG-250, etc.) civilian tungsten arc welding machine, the brand of tungsten arc welding is relatively professional.The series welding machine adopts the third generation inverter ----MOS-FET effect tube inverter technology, the market retains a large quantity, and the public praise is also good. Welding quality is relatively stable.More than 300A industrial tungsten arc welding, using a more mature fourth generation inverter ----IGBT module (or even dual IGBT module welding machine), consider other brands. The brand is only good at MOS-FET field effect tube technology. The IGBT module, industrial tungsten arc welding, is not very good at it.

Q: How can argon arc welding machine be changed into plasma cutting machine?

Argon arc welding machine into plasma cutting machine, first of all to see if the power is enough. Positive and negative polarity should be distinguished. With a torch. Remind me that it burns easily. Not cost-effective。

Q: There are several argon arc welding machines in our factory. There is a problem with it. To put it plainly, sometimes it can lead to arc. Sometimes it is very close and can not arc. Abnormal welding. Come on, master!

First, it may be too high or too weak or high frequency! Second, tungsten quality is poor, third welding torch copper wire open!

Q: Thin stainless steel by argon arc welding? [around 0.7]? How to use argon arc welding machine? What is the current size of argon?

.7 OK, not too thin.Pulse welder is the best.Porcelain mouth as small as possible, needle point as close as possible, tungsten as far as possible to sharpen the taper, a little bigger, that is, a bit sharp.5 litres / minute will be enough,Current 40A

Q: Argon arc welding machine does not arc, protection lamp is bright

The red light may have two kinds: the machine in 1. due to overheating, overload long time machine heat is too high due to thermal protection, machine level stop output, the red light, then we used to call "thermal protection lights," 2. machine level fault or misoperation fault at the machine level will stop output, red light we used, called "fault light"The difference between the two: when the red light, has been unable to welding, then do not turn off the power by the cooling fan operation, observed a few minutes, such as red light welding and output, proved to be thermal protection, can continue to work, if long time light does not extinguish, the machine is still no output, must promptly turn off the power to exclude faultMost current models are used only to show the red light Lei of the above two cases, so it should be the correct identification, timely treatment for reference.

Q: Direct connection method of direct current arc welding machine and how to select reverse connection in production

Now we generally welding rod is not divided into positive and negative connection method (feel sticky electrode can be reverse test). Our commonly used J422 is an acid electrode (leather), both reverse and positive can be. Unless there is a special electrode. Such as 507506427 basic electrode. We should use DC reverse connection in welding. Positive electrode. Usually guns are negative. Earth is positive.

Q: Argon arc welding machine does not arc, ground wire, welding torch is normal, what's the matter?

Scratch, arc, can normal welding?Not repairCan increase the discharge gap.

Q: Argon arc welding machine why arc small, current is small, how can I solve?

You use or old-fashioned power rectifier argon arc welding bar, small current is auxiliary superimposed power supply, the main circuit of the electric output, which is not specific, and suddenly said it is not clear.
