Q: My existing AC arc welding machine is 200 of the power is too small, I would like to put the home of a 400 AC welder with 200 AC arc welding machine together, do not know whether it is good to change, please experts advice, thank you!

1, can be directly connected to the argon arc welding torch, of course, have to connect the gas road, the current to the desired position, the line of arc (that is, contact short circuit, arc), direct welding can be2, note: welding torch negative electrode

Q: 400 DC argon arc welding machine, I'm going to buy a reallink in Taobao online! Just don't know what the credibility is!

Reallink is welding inverter, one of the earliest.Recommended Christie, the original is reallink sub brand, then points out alone, now also listed.With advanced technology, reallink ratio, the price is slightly lower.

Q: What effect the quality of Andre micro argon arc welding machine?

Not so well.This is only sold in a shop welder, there is no entity store. The welder also does not have after-sales service, and the welding machine adopts the OEM which is assembled by the renovation or inferior parts. Filter capacitor, main transformer, high frequency board (high frequency arc starting) and other key components, seriously Jerry built, using MOS-FET FET inverter technology, there are dangerous pipes.

Q: The current is too small to the maximum, indicating more than 300 or not

There are two problems. One is that the current potentiometer is out of order, and the other is your motherboard. If the line is not in good contact, the problem will occur

Q: What are the advantages and disadvantages of the plasma arc welding machine in comparison with other welding methods?

Plasma arc welding, compared with other welding methods, has Plasma arc, also called compression arc, is used for welding. It has high welding temperature, heat concentration, high energy density, high arc stability and good weld formation. It is suitable for welding of ultra thin welding parts and heavy bulky parts. The drawback is that the equipment is complex and demanding of the operator.

Q: What accessories does argon arc welding machine need?

Welding torch (tungsten pole, tungsten pole chuck, tungsten electrode press cap, ceramic nozzle), earth wire, welding mask, etc..

Q: The argon arc welding machine ground wire will leak, what's the matter, looking for a long time can not find the reason, have been it several times

Reason：High frequency electricity, pay attention to cleaning the dirt at the interface, arc when the tungsten is not too far away from the workpiece.High frequency electricity:The high frequency current is the current relative to the power frequency 50HZ alternating current. For example, the carrier current in a communication signal is a high frequency current. In some cases, in order to change the speed of the motor, it is necessary to use a converter to change the power frequency current into a relatively high frequency current, also called a high-frequency current. High frequency currents sometimes have an obvious radiation effect and can even cause harm to humans. Of course, some less powerful high-frequency currents do no harm to the human body. One important characteristic of high frequency currents is the skin effect, such as a solid conductor, which usually runs on its surface instead of the entire conductor. In comparison with the power frequency current, a characteristic of the high-frequency current is that the fatality rate will decrease after the electric shock, and the higher the frequency, the lower the fatality rate. The alternating current above 20000 Hz is a high frequency current.

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

The general welding process are taken in low voltage, high current process parameters for welding, argon arc welding machine has two kinds of welding methods, one is set to normal welding, a special set for the four step, but as said above two kinds of welding methods in local parameters of arc greater than the normal welding parameters, this is because the workpiece started when welding workpiece is cold heat output slightly, but this also prone to crack, so usually at the start of an arc increase an arc plate to prevent the generation of cracks in weld normal. Hope to be of help to you!

Q: Common faults and maintenance methods of DC invert manual arc welding machineWho has the relevant circuit diagram?For example, the market style: ZX7-200, MMA-160, ARC-200 and other modelsWhat does the letter "ZX7 MMA ARC" mean?Are they all invert DC manual arc welding machines?

TroubleshootingThe switch power supply indicator is not on, the fan does not turn, no welding output, 1, confirm the power switch closed.2. Make sure that the input cable is connected to the power supply.Power indicator light, fan does not turn, no welding output 1, may be wrong input on the 380V power supply, causing over-voltage protection circuit start, change to 220VPower on, you can reboot.2, 220V instability (power input line or too long) or input lines overlap in the grid, resulting in over-voltage protection circuit starting, increase input line grid line diameter; the fastening input line node, this phenomenon is shut down 5-10 minutes after the restart recovery.3, a short time continuous open and close power switch, cause over-voltage protection circuit start, shutdown 5-10 minutes later, restart, you can return to normal.4. The wire between the power switch and the power board is loosened and re tightened.5 、 the 24V relay on the power board is not attracted or damaged, check the 24V power supply and relay, and the relay can be replaced by other relays of the same type.When the fan is turned and welded, the output current is unstable or not controlled by potentiometer. When the current is large, it is small 1, potentiometer 1K, and the quality is not good. Should be replaced.

Q: What are the welding electrodes and argon arc welding machines used for welding machines?

Stainless steel wire! I just do stainless steel, what do not understand, despite asking me!
