Q: Can argon arc welding machine be changed into common DC welder?: The principle of argon arc welding machine and DC welding machine is similar, and all of them are drop characteristics. As long as the solenoid valve high frequency argon arc welding, argon welding and gas off, then the gun switch machine is short circuited, DC welder, welding torch and wire at the same time to swap (with argon arc welding torch grounding wire, grounding wire connecting welding).

Q: 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!!!

Q: What's the equivalent of 17KVA's AC arc welder?: 17KVA is 17 kilowatts

Q: Ask that master to help, ah, my welding machine is broken, the circuit diagram is not.: Performance characteristics: welding current minimum, from 10A (except WSE-180), stable arc performance, welding thin, medium and thick plates. DC pulse argon arc welding is suitable for welding stainless steel, copper, titanium, carbon steel and other materials. Besides, the characteristics of sag and descent can be obtained, and the welding current waveform is a square wave with fast zero crossing, which is beneficial to welding current and arc stability. AC argon arc welding is suitable for welding aluminum, magnesium alloy and other materials. By adjusting the pulse current and pulse frequency, the weld width, penetration depth and the number of weld ripples are controlled, and the weld seam is even and beautiful. Pulse time, pulse base time, atomizing zone regulation, gas lag and turn off time are all regulated without polarity, which can meet the requirement of higher welding process. It has the functions of AC and DC argon arc welding, AC and DC pulsed argon arc welding, AC and DC manual general welding, AC and DC spot welding. With welding current slow rise and decay functions are conducive to the current arc attenuation to fill the crater, avoid cracks.

Q: What is the power of this argon arc welding machine?: Three hundred and eighty welding machine capacity, no-load current multiplied by five. The single-phase AC welding transformer is actually a special step-down transformer. Compared with the common transformer, its basic working principle is approximately the same. In order to meet the requirements of welding process, the welding transformer works in short circuit and requires certain arc striking voltage during welding. When the welding current is increased, a sharp decline in output voltage, when the voltage drops to zero (i.e. two short side), two side current is not too big, and so on, the welding transformer has a steep drop in the external characteristics of the welding transformer, dropping characteristic is the pressure generated by the obtained reactance coil. No load, because there is no welding current through, the reactance coil does not produce pressure drop, at this time the no-load voltage is equal to the two voltage, that is to say, when the welding transformer is no-load, the same as the ordinary transformer no-load. The no-load current of the transformer is generally about 6%~8% of the rated current (the State shall not exceed 10% of the rated current). This is the theoretical basis of formulas and the.

Q: What's the difference between pulsed direct current welding machine and inverter argon arc welding machine?: If your problem from the internal structure that is a bit complicated, we say that it is the function of it, the former is generally used to direct welding for carbon steel, stainless steel, copper alloy and steel, steel welding; the latter should be added to argon welding, usually used for welding of stainless steel materials.

Q: Can argon arc welding machine be used instead of plasma cutting machine?: This is really impossible.The common point of argon arc plasma cutting is direct current high frequency arc ignition.The difference is thatArgon arc welding welding voltage is very low, about 10 volts to more than 20 volts.Plasma cutting machine no-load voltage of more than 200 volts, the operating voltage is more than 100 volts or even higher.

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: Who used the three Joe brand argon arc welding machine? What's the quality?: Haven't heard, is brand-name products, is not recommended.But it does not mean that the quality will not, but that there is a high probability of quality problems.In addition, the actual parameters of the welding machine may not reach the nominal value.Now the big brand welding machine is not expensive, brand-name machine even cheaper, if the maintenance time, may be more expensive, as for the effect of using your own loss calculation.

Q: Viva WS-200S dual inverter DC argon arc welding / manual welding of the fault: Argon arc welding, the power switch can be welded open, the current is very large, can not be closed, high near the ignition
