Technical Parameters

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!: Just to be brief with you: WS ordinary argon arc welding, you welding is suitable. WSM: argon arc welding with many pulsed functions, which can be soldered to an automatic arm (pulse). Wsme: the argon arc welding of 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:Can argon arc welding machine weld copper?: Can. But the cost is high. It is difficult to weld brass (including zinc) by argon arc welding.

Q:What causes the DC argon arc welding machine to interfere with the automatic step motor?: Argon arc welding has high arc impulse

Q:What does the 315 argon arc welder cool with water?: 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.

Q:I would like to ask the next ZX7-400 inverter DC welder quite a number of watts of power, thank you: ZX7-400 type inverter direct current welding machine works normally, equivalent to 16.9 kilowatts of power. This is the rated power, the specific use may vary slightly.

Q:What's wrong with argon arc welding machines without high voltage output?: The induction coil doesn't know where it is, it's only for professionals to fix it.

Q:How much is the used argon arc welder now? How much is the cheapest argon arc welder? (welded stainless steel burglarproof window): For your application, single phase 200A is enough, about 1000 new ones;Second-hand hard to say, depends on the specific circumstances. But I still suggest you buy a new one, reallink better, stable quality.

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:What is the optimum distance between the arc striking of argon arc welding machine?: Two discharge points per discharge point 0.1~0.3mm, isoelectric point 0.2~0.5mm is suitable for delivery.

Q:Two can welding machine be used as argon arc welding machine?: Carbon dioxide welding is a manual welding a good process, but its performance can not be completely argon arc welding and similar welding compared.In contrast, argon arc welding is easier to control the size of the weld pool, welding metal molding, heat energy is very small, the most suitable welding thin plate.Carbon dioxide welding can only weld more than 1mm of sheet metal, argon arc welding can be welded to about 0.2mm of the sheet. Cannot compare
