Q:High frequency automatic discharge of argon arc welding machine, professional engineers? Yangcheng anda TIG-250 inverter argon arc welding machine to control the line to take high frequency or discharge can be welded, but not stable, no gas output, what is wrong with the place, please Engineer pointing. Thank you: The high frequency arc striking circuit automatically closes and disconnects the high voltage arc striking circuit under the control of the current variation induction circuit. The capacitor is discharged by a thyristor to a coil, because the discharge current is large and the time is short, and the magnetic field is very large

Q:Also, how can I choose the model?: Orrett argon arc welding machine new products are listed in detail. Hefei four friends Electromechanical Equipment Co., Ltd.

Q:Can the inverter DC argon arc welding machine weld aluminum?: It's better to buy an AC argon arc welding machine

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: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 power of the BX1-315 AC arc welder?: No more than 15Kw

Q:When the thickness of the welded stainless steel plate reaches 1.2 millimeters, how should the duty ratio be adjusted so that the welding can achieve the best effect?! Thank you: Characteristics of pulsed direct current

Q:I have a 380V three-phase DC argon arc welding machine, can not be changed to 220V single-phase DC argon arc welding machine? Thanks for your help!: 380V three-phase argon arc welding machine can not be changed into 220V single-phase, because the 220V voltage can not drive three-phase argon arc welding, so the welder will not work at all.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 material to a welding technology of metallurgical bonding.

Q:Why does the argon arc welding machine burn the black stick?: There are many reasons for tungsten burning:1, check and between tungsten argon arc welding torch position: clearance clamping with the clamping seat or between the gun body is too large, if it leads to poor conductivity, when in lighting, too close to the metal, the instantaneous current greatly, concentrated heat, not only will stick the needle, and will lead to loss; in addition, position is not correct, will lead to poor cooling, can also cause damage. So try to tighten the cap and check whether the tungsten electrode is reliably fixed. When purchasing, it is necessary to choose a closer clamping and clamping seat.2, check whether the standard AR (four 9 standard, namely the purity of argon must reach 99.99% or above), if the argon impure, cause of tungsten inadequate protection, easy burning; in addition to check whether the leak; one of the factors also affect the quality of tungsten.3, according to the welding machine AC and DC to correct wiring.(1) if it is a direct current welding machine, the ground wire is connected to the positive pole, the welding torch is connected to the negative pole; if the connection is reversed, the tungsten electrode is burnt out;(2) if AC and DC welding machines are used, the burning of tungsten will be more serious in the case of ac;

Q:What's the price of argon arc welding machine?: Argon arc welding machine has DC, pulse, AC and other types, the size of the market has a small general argon arc welding machine 700-1000 yuan
