Q:You ask about the quality of argon arc welding machine which brand is good, the requirements of aluminum welding, welding and cutting thickness below 20mm, 12mm can also be used, or DC inverter AC / DC, what model is appropriate, about how much the price, thank you!

Salesman to answer, are deceptive, the market share of the most is the best.

Q:Which brand of AC arc welding machines is of the best quality?

First name: Miller good welding effect, concentrated arc, strong firepower. Especially the effect of welding of aluminum is the most outstanding. In addition to this brand welding machine especially durable. If an enterprise is allowed if economic conditions I strongly recommend this brand.Second place: Tangshan Panasonic: the advantages of welding function is all. Welding effect is very good, especially stainless steel small current arc success rate. Shortcomings: performance is not stable, repair rate is high. Service life is shorter than MillerThird: Shenzhen reallink quality, the biggest advantage of this card machine low price good. The average user is strongly recommended.Fourth: the general quality of the TIG welding machine the biggest drawback of Japan OTC the two Danish migatronic brand, high price. Strictly speaking migatronic a little better.Fifth: Shanghai Weiteli welding stainless steel has the advantages of good effect, good arc welding of aluminum arc. The shortcoming is too hard. The price is reallink much higher.

Q:Just bought a reallink argon arc welding WS200S, there is a gas delay switch, I do not know how to use, who can answer! Thank you

2.5S and 5S conversion, how long will it take to use?

Q:What do you mean by "ground arc" of argon arc welding machine? Is it because it doesn't arc or is it connected directly to the ground to prevent electric shock?

In order to form a loop, not a safety problem, the welding gun is an electrode and the ground wire is an electrode, so as to form a welding arc

Q:Can argon arc welding machine be welded without argon gas?

No, you first need to understand the role of argon, argon is inert gas, almost without any material reaction (limit exceptions), so use it to open air, high temperature protection welding metal and welding torch tungsten pole argon arc welding is often used for sheet metal or lively, for example: very thin carbon steel, stainless steel and so on, if the AC argon arc welding, aluminum welding can Aluminum Alloy.Without argon protection, 1, the welding of high temperature metal will react with the air, blackening, porosity, welding quality is very poor. 2. The tungsten electrode of the welding gun reacts with the air and burns rapidly.Think about it, your tungsten filament bulb, if you remove the glass cover, quite in contact with the air, tungsten filament instant evaporation!

Q:Inverter type argon arc welding machine can not be welded without squeaking sound

The DC inverter argon arc welding machine welding can not have a squeaky voice, the voice is generally arc starting circuit of high voltage discharge sound, high-pressure arc starting circuit is normal, and this is the main fault of high pressure air breakdown to argon arc welding inverter DC 70V arc work. Check whether the positive and negative electrode output voltage is 70V DC voltage (remember not to press the hand switch when measuring!! Otherwise, the high pressure will break through the burn out multimeter!!! Then change the welding handle or change the internal electrode of the handle. In many cases, the welding handle is aging.

Q:How to set the aluminum welding argon arc welder?

For pure aluminum, tungsten argon arc welding is recommended, with a semi-circular removable plate (austenitic stainless steel or copper backing plate) Before welding, remove the oxide film without melting. After the weld is finished, the stainless steel wire brush is used to polish it down, except for the oxide layer on the shallow surface.

Q:Can argon arc welding machine be changed into two welding machine?

Tolerable。Argon arc welding machine can not be replaced by two welding, both of which are different from inner structure.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.Two welding process is suitable for low carbon steel and low alloy high strength steel of various large steel structure welding, the welding of high productivity, good crack resistance, small welding deformation, adapt to the deformation range, can be thin and medium thick plate welding.

Q:What kind of argon arc welding machine is used is manual welding and argon arc welding switch? What's the connection between direct current and pulse? The more detailed the better, for example, when to switch to manual welding, when the use of argon arc welding, when the use of DC or pulse, how they match, and so on. ThanksAlso, what are the main aspects of direct current argon arc welding? What's welding? What are the main uses of pulse argon arc welding? What's welding? Is manual welding direct current or pulse? What's the main weld? Manual welding is not the kind of electrode welding?

This is your welding machine DC welding machine, it has two kinds of manual welding and argon arc welding, manual welding is the welding, soldering or welding can, stainless steel, argon arc welding can also iron welding of stainless steel. A pulse is in the welding process, as is your pulse, jump when welding, when the jump is not welding, when you press the switch, it will fire pounding, in fact it is working in high current low current, high current work. Then, low current work, continuous circulation, circulation speed can be fast or slow, you should adjust current regulation of the highest and the lowest current switch, you let it stop. The general pulse is used to burn automatic welding, the welding effect scales with more. Here you don't actually mean DC pulse, you switch it by welding, it will not upset the meaning of welding switch.

Q:What's the difference between argon arc welding machine 380V with two wire input and three wire input?

Two arc welding argon arc welding machine is single-phase 380V.The argon arc welding machine with three wire inputs is three-phase 380V.Three phase argon arc welding machine has good stability. Now the inverter arc welding is the power input mode.Because of the unbalanced voltage of the network, the welding parameters of single-phase arc welding is poor. Mainly old-fashioned frequency AC arc welding machine based. Backward technology.
