Q: What are the well-known automatic argon arc welding machines in the world?

If you ask is basically the TIG welding machine, various materials can be used, cheap OTC, Panasonic, expensive EWM, kemppi etc.;If it is MIG welding machine, welding aluminum alloy FRONIUS, SAF and KEMPPI are good, welding stainless steel SAF, EWM can;If it is MAG welding machine, welding carbon steel SAF, KEMPPI, LINCON and so on;The main thing is to see your specific needs

Q: What gas does argon arc welding machine use?

Argon gas arc welding machine, the most commonly used inert gas is argon. It is colorless and odorless. The air content is 0.935% (by volume), the boiling point of argon 186 C between boiling point between oxygen and helium. Argon is a by-product of oxygen production by liquid oxygen from an oxygen plant.Bottled argon is used for welding in China and the filling pressure is 15MPa at room temperature. The cylinder is painted with gray paint and marked "argon". The chemical composition of pure argon requirements: Ar = 99.99%; He = 0.01%; O2 = 0.0015%; H2 = 0.0005%; the total amount of carbon less than 0.001%; the water is less than or equal to 30mg/m3.Argon is an ideal protective gas density than air in 25%, is conducive to the protection of welding arc welding, reduce the consumption of protective gas. Argon is a chemically inert gas that does not react with metals even at high temperatures, without alloy oxidation, burning, and a range of problems. Argon is also insoluble in liquid metals and hence does not cause pores. Argon is a monatomic gas that exists in an atomic state and has no molecular decomposition or atomic absorption at high temperature. The specific heat and heat conduction capacity of argon are small, that is to say, the amount of absorption is small, the heat to the outside is less, the heat in the arc is not easy to dissipate, the welding arc is stable and the heat concentration is concentrated, which is beneficial to the welding.The disadvantage of argon is that the ionization potential is higher. When the arc space is full of argon, the arc ignition is difficult, but once the arc is ignited, it is very stable.

Q: Which is the best welding torch for argon arc welding machine?

It's a good idea. Judging by weight, the quality is very effective for this kind of conductive material. We recommend Daewoo welding equipment. The design is reasonable in price and the price is higher

Q: The current is too small to the maximum, indicating more than 300 or not

Argon arc welding welding current adjusting welding current of TIG welding is usually chosen according to the space position of the workpiece material, thickness and joint, when the welding current is added, the penetration depth increases, the weld bead width and height increased slightly, but little increase, the welding current is too large or too small will cause the poor weld shape or welding defects, the position of the welding current to 80 ~ 110A is better, the ideal current value is 90A, when the spot welding current to 150 ~ 180A is better, the ideal current value is 160A.

Q: I want to weld pressure 3.52MPa pipe, argon arc welding, manual welding cover surface. In the online search WS WSM, argon arc welding and WSME three models, it is not clear which is suitable for professionals to give guidance, please, thanks in advance!

Inverter: ordinary argon arc welding, you welding is suitable.Pulse: argon arc welding with many pulsed functions, which can be soldered to an automatic arm (pulse).Square wave TIG welder: argon arc square wave function, using square wave welding aluminum oxide layer on the surface of the square wave (open aluminum oxide layer with high melting temperature, need to open the square wave, the internal aluminum low melting temperature).

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: I purchased a reallink WS-200S argon arc welding machine, sometimes want to burn the common hand arc welding, ask how to modify it with?

Why not buy WS-200A, argon arc and manual welding dual-use, and also not expensive, you arc so troublesome, and the effect is not so good...

Q: Argon arc welding machine why arc small, current is small, how can I solve?

The general welding process are taken in low voltage, high current process parameters for welding, argon arc welding machine has two kinds of welding methods, one is set to normal welding, a special set for the four step, but as said above two kinds of welding methods in local parameters of arc greater than the normal welding parameters, this is because the workpiece started when welding workpiece is cold heat output slightly, but this also prone to crack, so usually at the start of an arc increase an arc plate to prevent the generation of cracks in weld normal. Hope to be of help to you!

Q: Reallink Christie and argon arc welding machine which is good, what are the advantages

The two are produced by a factory. Now called Christie.

Q: Can argon arc welding machine be used as cutting machine?

No, it can be used as an electric welder. You want to make a cutting machine. Buy a plasma bar with that!
