Q:I have a household type 200 inverter manual welding machine. I want to weld stainless steel. Can you change it into argon arc welding machine?: Hard。。 With high frequency circuit, argon welding to hand welding can be very simple

Q:There are several kinds of arc welding machine, argon arc welding machine and several kinds. What are their occupational hazards?: Answer: We specialize in the production of electric welding machine: this should be a detailed classification, very complicated. I'll give you a brief description of several types of fusion welding:Manual arc weldingArgon tungsten arc weldingCarbon dioxide gas shielded arc weldingsubmerged arc weldingmetal inert-gas weldingThe common characteristics of occupational hazards are:1. smoke and harmful gases produced by welding2. arc damage to human skin3. electromagnetic field harm to human body4. noise effects on hearing, etc..

Q:What is the power of this argon arc welding machine?: Three hundred and eighty welding machine capacity, no-load current multiplied by five. The single-phase AC welding transformer is actually a special step-down transformer. Compared with the common transformer, its basic working principle is approximately the same. In order to meet the requirements of welding process, the welding transformer works in short circuit and requires certain arc striking voltage during welding. When the welding current is increased, a sharp decline in output voltage, when the voltage drops to zero (i.e. two short side), two side current is not too big, and so on, the welding transformer has a steep drop in the external characteristics of the welding transformer, dropping characteristic is the pressure generated by the obtained reactance coil. No load, because there is no welding current through, the reactance coil does not produce pressure drop, at this time the no-load voltage is equal to the two voltage, that is to say, when the welding transformer is no-load, the same as the ordinary transformer no-load. The no-load current of the transformer is generally about 6%~8% of the rated current (the State shall not exceed 10% of the rated current). This is the theoretical basis of formulas and the.

Q:What is the straight line mark on an argon arc welding machine?: A straight line is an ordinary DC output gear. The the Great Wall icon is the AC square pulse output chart. 2T is the switch on the welding torch, manual control welding machine switch. 4T is automatic welding without welding gun switch control.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: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,: Argon is an inert gas that blocks air and protects the workpiece from oxidation at high temperatures. The nitrogen reacts with the air after the arc is electrically shocked, producing nitric oxide and starting to act as a protective agent.

Q:Can argon arc welding machine be equipped with automatic wire feeding device?: Argon arc welding machine can be equipped with automatic wire feeding device. The working process of the automatic wire feeding device is as follows:1. The wire feeding machine main body, the wire feed nozzle is connected by the feeding pipe, and the suitable silk disk is installed.2, such as the use of the foot switch control wire and spinning, only the foot switch and the control panel on the wire drawing interface; such as the use of the torch high frequency switch synchronous control wire is spinning, high frequency interface control panel on the outgoing interface and high frequency argon arc welding on the connection, then the high frequency control high frequency on the panel into line with the torch of arc connection.3. If the upper computer needs to control the wire feeder, the internal control communication switch on the control panel should be placed on the communication side. If the upper feeder is not required to control the wire feeder, the internal control communication switch in the control panel shall be placed on the inner side of the control.4. According to the diameter of the selected wire, fit the wire feed wheel.5, the power plug is connected, turn on the power switch, and the wire feeding speed regulation to the fastest, pressing pressure rod, tread down pedal switch, or use the control wire drawing the switch on the panel, the wire feeding mouth to arrive as soon as possible. When the wire passes through the wire feed nozzle, the wire is stopped.6 、 adjust the wire feed nozzle to meet the demand of welding angle. Adjust the parameters of wire feed machine and select the appropriate feeding method to reach the proper speed.7. Turn on the welding machine and weld properly.8. After welding, turn off the power switch and unplug the power plug.

Q:The argon arc welding machine ground wire will leak, what's the matter, looking for a long time can not find the reason, have been it several times: Your welding gun is not insulated well

Q:I see the model number "IA-300ITPS". What does that mean?: Alternating or alternating pulses are possible. Because the aluminum alloy surface has oxide film.

Q:Argon arc welding machine is not gas ignition what happened?: Check the control switch and the circuit is short, if not, then look inside a gap is too large surface is clean. No problem, according to the line has been checked. Some welding machines are set up without air flow and arc free. If the arc striking device is striking the arc, check the gun belt.

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?: Yes, it can be used with an argon arc welding torch with a switching interface and a trachea, but the effect is not very good, or a special argon arc welder is recommended.Argon arc welding is a special welding machine, which needs argon and water cooling.
