Q: What causes the DC argon arc welding machine to interfere with the automatic step motor?: The stepper motor driver controls the stepper motor by controlling the pulse. If the drive pulse bandwidth is too wide or the wiring is not reasonable, the control pulse will be disturbed. Argon arc welding produces large electromagnetic interference signals at arcing time.

Q: Why does the argon arc welding machine burn the black stick?: The current selection is large, the tungsten needle is too close to the dissolution bath, and the suitable current is selected. The tungsten needle with suitable diameter is operated with an hour head and a proper distance from the dissolving bath, and the speed is right

Q: It's only a small electrical shock when soldering..: Causes and solutions of non arcing of argon arc welding machine:1 、 the gap of the discharger and the looseness of the screw. Tighten the screws;2 、 the joint looseness of the whole arc striking circuit. Reconnect the line connections again;3, there are quality problems of arc welding high pressure package. Need to replace the high pressure bag;4, electronic components (loose) weld welding foot problems. Re welding.Extension of knowledge point:Argon arc welding is a kind of welding technology using argon gas as protective gas. Also called argon gas shielded welding. That is, argon shielded gas is applied around the arc welding, and the air is separated from the welding zone to prevent the oxidation of the welding zone.Argon arc welding technology is based on the principle of arc welding on using argon protection for metal welding, the welding material in high current to be welded on the substrate is melted into liquid form of molten pool, the metal to be welded and welding welding technology to achieve a metallurgical combination, due to the high temperature melting on argon welding continuous feeding in the welding material can not contact with oxygen in the air, thereby preventing the material oxidation, therefore can welding stainless steel, iron metal hardware.

Q: How is the direct connection and reverse connection of the direct current arc welding machine? On what occasions are they used?: By using the direct current connection method, the workpiece is connected to the anode. Because the temperature in the anode zone is higher than that in the cathode zone, the workpiece is deep melted and the welding rod melts slowly. It is suitable for welding the workpiece with thicker thickness.When the DC reverse connection is used, the welding rod meets the anode, and the welding rod melts faster, while the workpiece has a lower melting depth. This method of arc is relatively stable, and it is difficult to generate hydrogen pores. Suitable for welding thin steel plate, nonferrous metal, stainless steel, surfacing welding and welding of basic welding rod.

Q: How does the argon arc welder overheat protection?: See if the fan is not good, use the compressed air to clean the dust inside the machine, the machine is overloaded, the power is too small (for power point welding machine or increase cooling capacity)

Q: Commonly used electrical welding machine (AC) why, some of the object is AC welding machine, and some of the object is AC arc welding machine, what is the difference between the two; do not pull useless, I am not high culture, thank you for your cooperation!: There are two kinds of communication. One is directly step-down through a transformer.. There is another way to convert AC into direct current and then DC to ac.. The advantage of the former is that the price is cheap and the structure is simple. The latter has the advantages of long service life, low welding cost, convenient module maintenance and light weight.

Q: The difference between AC argon arc welding machine and DC welder: Compared with AC power supply, the DC power supply can provide stable arc and stable droplet transfer. Once the arc is ignited, DC arc can maintain continuous combustion; AC welding power source, the voltage and current change of direction, and every second to extinguish the arc and re ignited 120 times, arc can not be continuous and stable combustion. In the case of low welding current, the DC arc has a very good wetting effect on the melted weld metal, and can regulate the weld size, so it is very suitable for welding thin parts. DC power supply is more suitable for overhead welding and vertical welding than AC power supply, because DC arc is relatively short. But sometimes the arc of DC power supply is a prominent problem, and the solution is to change to AC power supply. For the AC or DC power supply welding and design of AC and DC dual electrode, the vast majority of DC power supply conditions in the welding applications better. In manual arc welding, the AC welder and some additional devices are cheap and can avoid the harmful effects of arc blowing force as much as possible. But in addition to lower equipment costs, the use of AC power supply welding effect is better than the DC power supply. The arc welding power source (CC) with steep drop characteristics is most suitable for manual arc welding. The voltage change corresponding to the current change shows that the current decreases with the increase of arc length. This characteristic limits the arc current even if the welder controls the size of the bath. When the welder moves the electrode along the weldment, it is inevitable that the length of the arc changes constantly, while the steep down arc welding power supply ensures the stability of the arc during these changes.

Q: Argon arc welding machine welding torch has been pressed out, wait a few seconds will stop, which does not press the switch will be out of gas? What's the problem?!: Electric welding machine is no problem, this is a standard function of argon arc welding, called lag aspirated, just stop in order to protect the high temperature molten pool during welding, you stop welding torch while power, but the temperature will not weld suddenly drop, if there is no protection, high temperature metal oxide will form pores;So in the welding stop after the protective gas have to a good protective effect to form so as to remind you: also, after soldering, do not immediately put the gun away, until the weld metal cools off again, this time to protect gas or sprayed on the white blow!

Q: How can the argon arc welding machine adjust the operating voltage range?: When the argon welder is constant current, the operating voltage varies with the operating current, and no adjustment is needed. If the work voltage is changed forcibly, the welding machine will not work properly

Q: Model BX6-315-2There are 4 terminals on the input side, one time two thread heads, two times two thread heads, the right side of the 380V, the left 220V, how can I get the 220V power supply?Senior guidance please: The input side is three lines, the output side is four lines, the input side one is a common end, 380, 220 share of the output side to wait for you to pick a power of good judgment, with a multimeter voltage between the lines, there is a on the other three voltage are about 70 volts, the root is ground, the other three is large, welding machine, small three stalls. Just ask the welder to try it yourself and don't need any points. Oh, I think you can connect 220 volt electrical test, welding work on the normal work is wrong, then try again, anyway, the welding machine is wrong, as long as they do not work for a long time, not bad.
