Technical Parameters

Q: (reallink authentic) inverter DC TIG / arc welder WS-300A how to use the reallink dual-purpose welding?: The red knob is a current size adjustment, is a function of manual welding when thrust regulation (welding current welding at large strengthening efforts) switch alone know how to use it?

Q: What's the reason for this? Tell me about the trouble. I work in argon arc welding, the novice today, dry with a dry suddenly broken, the arc, I thought is a switch or circuit which is broken, later discovered, with tungsten tip with the welding surface contact, causes a spark. What are the reasons for seeking advice?.: Striking, arc striking, welding can be normal, that is, high pressure arc part of the fault.Generally high voltage capacitor aging.

Q: Used welding machine welder, argon arc welding machine for sale: You can register on the home of the welding website and publish the second-hand information, which is very convenient and quick!

Q: Can argon arc welding machine be cut?: Argon arc welding machine can be cut.Argon arc welding uses argon to protect the weld from oxidation.The cut does not require argon and requires compressed air to blow the molten metal.Just emphasize one point: change the handle with plasma cutting.The gas path is connected with the air outlet, and the other is welded by the argon arc welding method, and then an air compressor is needed to receive the air inlet end of the welding machine air inlet.The internal gas off gas and is composed of an electromagnetic valve control, when the handle switch is pressed, can automatically achieve the breakdown of air arc and gas, timely blow molten metal, to achieve the purpose of cutting metal.

Q: Argon arc welding machine arc arc is not how ah?: 1: switch damage, (replacement) 2: welding machine delay settings (check, delay setting and recovery), there are two possibilities.

Q: Why argon arc welding only fires without current?: There may be a high pressure package will be bad, but generally not high voltage package failure. Argon arc welding machine is not a simple welder with argon gas protection. On the one hand, the no-load voltage is low; on the other hand, it is possible to reduce the capacitive capacity of the high voltage arc ignition circuit.Argon arc welding machine slow ignition, this normal. After pressing the switch of the welding torch, the electromagnetic valve in the welder is started.Argon arc welding machine, are ahead of its protection role of gas welding. Argon is used to blow air around the weld line of the workpiece to be welded so as to avoid penetration of the weld through the air. The arc then starts and enters the normal welding process.Each brand of each model of argon arc welding machine, the delay time is different, some welding machine can be adjusted.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: Can argon arc welding machine be welded directly with electrode?: Yes, if you have a manual welding converter switch on argon arc welding.

Q: ZX7 inverter type DC arc welding machine, when the welding current is 150A, how much power can it have?: Probably can only be calculated when welding in general, because of the arc, the arc of that moment consumption is relatively large, the arc voltage of 70V welding voltage is about 30V, according to Ohm's law 30 multiplied by 150 ampere voltage =4500W is 4.5 kW and its loss is less than 100W and the total power should not arc to 5KW, the welder should also consider the sustained load, generally less than 60% of the whole ZX7 is saving than at least half exchange

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 earth is not grounded, instructions should have positive ground requirements, if the ground, to see whether the welding poor insulation, ignition by high voltage pulse breakdown voltage protection gas ignition, about three thousand, is the General Electric will be pitted, not life-threatening

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.
