- Q: There are several kinds of arc welding machine, argon arc welding machine and several kinds. What are their occupational hazards?
- Manual arc weldingArgon tungsten arc weldingCarbon dioxide gas shielded arc weldingsubmerged arc weldingmetal inert-gas welding
- 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: Isn't it? I feel OK, the first time there is no argon, the air can be usedThe nitrogen reacts with the air after the arc is electrically shocked, producing nitric oxide and starting to act as a protective agent. Wrong, this reaction occurs only at the periphery, and the reaction at the nozzle is pure nitrogen. There is no such problemHarmful gases can be solved by ventilation. What I care about is that if the metal nitrides are produced during welding, they will get very good welding hardness and corrosion resistance. Can they do so?The pure air did not work, and the tungsten electrode was soon ablated,
- May not！ Argon arc welding machines can only be used: welding and argon arc welding! I'm glad to answer that for you!
- Q: What is the function of an argon arc welding machine with current attenuation function?
- 1. Argon arc welding machine with current attenuation function can help arc striking.2, welding, welding materials (welding rod, welding wire, etc.) arc ignition process called arc. The arc striking methods commonly used in manual arc welding are stroke cleaning and direct striking.3, 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.
- 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: I want to buy Christie Bao WSE200P AC DC pulse argon arc welding machine, but do not know how about the quality?
- Christie's customer service no, I suggest to buy reallink, I just bought a WSE200P models, the reallink do good customer service. After all, that quality, welding inverter or the old brand on the live action,
- Q: The normal function of argon arc welding welding, arc not normal, press the switch can hear the fire place in the machine (what is I do not know the name, like the discharge gap? Is the two small pieces of metal plate - like contact not contact place) with loud no problem before, there are sparks. Some people say that the problem is the high frequency don't ask the master, the arc, which is the problem, can repair? Is worth repairing? Can not repair welding repair in our county those people say. Thank god!
- Put the appliance (that is, the 2 small metal plate) the gap is great, and then not to high voltage ceramic capacitor discharger beside the blue change.
- Q: Can the sub arc welder be used as an electric welder?
- No, two entirely different things
- Q: Pondering over this afternoon for a long time, that is, welding can not, and welding a little hard on the break, we set the 120-140A current, argon flow of about 1. We want to be the parameter is wrong, just don't know how to adjust, ask the welding master to answer,
- You can adjust the use of welding needle is the problem, to sharpen, flat welding, face to face, welding needle and porcelain mouth flat or concave into a little,When the welding angle is included, the welding needle protrudes 1 millimeters of the porcelain mouth, grasps the degree, and also releases the stuck gas before releasing the welding by pressing the hand switchWelding the workpiece again, the current can be a little bit bigger, 160A, a little bit, you will do it
