Features

1. Mature and reliable main circuit with balanced reactor and thyristor in dual inverse-star form, each moment has two thyristors work in same time, high efficiently

2. Rigorous process design, regardless of harsh environments or reload will operate properly

3. End voltage and current adjustable, regulate that help to make up the crater defects at the end of welding

4. With voltage and current adjusted separately/simple synergic function, whether newbies or skilled welders can easily operate.

Tips: If welding cable is longer than 5m, dual-driven wire feeder will be a better choice to reach better welding performance.

Q:What are the differences between invert DC hand arc welding machine ZX7-200T and ZX7-200?: There's no particular difference between this, ZX7-200T and ZX7-200 just say the names of each manufacturer, or the structure of the device is different.

Q:Say a little more; thank you: Also called arc welding arc welding transformer, is a kind of special transformer, the network voltage alternating current into low voltage alternating current suitable for welding, which is composed of the main transformer and the required adjustment part and indicating device etc.. Arc welding machine has three kinds of moving iron core, body type and moving coil type. The utility model has the advantages of simple structure, easy fabrication, easy maintenance, low cost and high efficiency. But the current waveform is sine wave output, AC decline characteristics, arc stability, low power factor, but the magnetic blow phenomenon rarely, no load loss, generally used in manual arc welding, submerged arc welding and TIG welding method.

Q:Can the direct current welder be used as an argon arc welding machine?: DC welding machine, in broad sense, as long as the output is direct current, belong to DC welder.Including two welding electrodes, hand arc welding, DC TIG welding machine, etc..Narrow sense, DC welding machine is: welding rod hand arc welding machine.Only welding rod arc welding machine, using strike arc, can be used as simple tungsten argon arc welding, the disadvantage is that the need for external gas control system. The larger the short-circuit current is, the more serious the tungsten electrode burns. The weld is easy to clamp tungsten.

Q:What argon arc welding machine is used in the circulating water tank of the welding truck? Copper and aluminum water tanks: The circulating water tank of copper is very thin, generally use electric iron used in soldering power of more than 100W, and use the acid flux, just clean the surface, some difficult, if it is the middle circulating water tank leak, can trap with temperature greater than 100 degrees AB, the effect is good, the middle of the circulating water tank argon arc welding it is difficult to implement trap

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:Argon arc welding machine automatic leakage, how to repair?: Change the solenoid valve slightly

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.

Q:What should the novice pay attention to when using argon arc welding machine? (the more detailed the better) thank you!!!: Strong attention; eye injury, burns, welding current adjustment, to be bold but cautious...

Q:Argon arc welding fan cooling fan does not turnBut to get the AC220V power test, the fan is good.: It is possible that the welder is out of order and that the following work can be done before repairs or repairs;1. Check whether the power supply for welding machine is power or not, and make sure the leakage protection switch is not tripping. It's all right with the multimeter;2. Check whether the power input cable of the welder is in good condition and make sure there is no disconnection;3. Ask professional maintenance personnel to disassemble the chassis and measure whether the input of the welder has electricity, and pay attention to safety!4. Make sure the power switch of the welder is good.

Q:Bought a new ZX7-400B inverter DC welding machine, the seller said it can be used as argon arc welding. My neighbor bought an argon arc welding machine. The model is ZX7-400S. The welder has two interfaces, and the manual switch for argon arc welding torch. I don't have these two interfaces. What's the difference between ZX7-400B and 400S? And can I use the welder as an argon arc welding machine?: Full digital software control to regulate welding function and parameters. The model is HB400-12, and 315 and 500anp.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.Non melting argon arc weldingNon MIG welding arc is non consumable (usually tungsten) between the workpiece and the inert gas from combustion, chemical reactions in the welding arc flows around a metal (usually with argon), forming a protective hood, the electrode, arc and weld pool and at high temperature the metal is not in contact with the air to prevent the oxidation and absorption of harmful gases. A compact welded joint is formed, and the mechanical properties of the welded joint are very good.MigThe welding wire is fed by the wire wheel, the conductive nozzle is electrically conductive, and the arc is generated between the base metal and the welding wire, so that the welding wire and the base metal are melted, and the arc is welded by the inert gas argon, and the molten metal is welded. The difference between it and TIG welding: a welding wire as electrode, and is constantly melting in molten pool, the condensation of the weld; another is a protective gas, with the application of MIG welding, gas protection has been widely used in variety of mixed gas of argon to develop a single, such as rich argon gas Ar 80%+CO220%. Usually the former is called MIG, and the latter is called MAG. According to its operation mode, the most widely used are argon arc welding and argon rich gas mixture welding, followed by automatic argon arc welding.
