Q:Difference between inverter, pulse and Fang Bo argon arc welding machine
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:What are the causes of arcing in argon arc welding machines without arcing?
The torch cable breaking is not completely broken, the high-frequency pathway is a high voltage low current, but the welding current is larger than the high-frequency current and the arc voltage is much lower when the welding voltage, welding torch cable problems when welding arc voltage is too low, so not arc.
Q:Should the DC arc welding machine be equipped with electricity saving, shock proof and leakage protector?
In principle, all electrical appliances need to install anti electric leakage switches (especially metal shells, electrical equipment) at the power input terminals, and the same with the welder.If the anti welding output of electric shock, you don't have to worry about this, on the market in the sale of the DC welder basically has the electric shock prevention function (VRD), the anti shock function after opening, the welding output load is generally not higher than 20V, two hands and two are positive and negative contact welding output terminal, there will not be any shock feel very safe. You can buy Welding machines with this function.As far as energy saving is concerned, it is only when the electric welding machine does not work for a long time, turn off the power supply to save electricity. Now with the inverter DC welding machine, transformer AC welding machine compared to old-fashioned, no-load loss is much smaller, if only a short period of time without welding, no need to put what sort of economizer, if it is a long time without welding, mind you directly off the welding machine.
Q:How can argon arc welding machine be changed into plasma cutting machine?
First. PowerSecond. Transformer voltageThird. Line class featuresFourth. If you don't do it well, it's easy to be bad
Q:What is an inverter argon arc welding machine?
AC into DC, called rectification, DC into AC, called inverter. The work process is the first inverter fifty Hz AC rectified DC to DC, mud into thousands of Hz to tens of kHz AC, and then use the transformer, then rectified a stable welding power supply. The advantages of inverter welding are light weight, small size, convenient welding flow regulation, stable welding flow, etc.
Q:What do you mean by "ground arc" of argon arc welding machine? Is it because it doesn't arc or is it connected directly to the ground to prevent electric shock?
In order to form a loop, not a safety problem, the welding gun is an electrode and the ground wire is an electrode, so as to form a welding arc
Q:What is the cause of the no ignition in the DC argon arc welding machine?
As you say, the machine should be all right! Here's a way. You can try: the tungsten electrode is close to the weldment, and the wire is rapidly crossed to make the weldment short circuited with the tungsten electrode in a very short time, which can well ignite the arc!! Have a try!
Q:PLC received high frequency interference from argon arc welding machine,
1, do power isolation, control circuit power supply, servo motor power supply must go through the isolation transformer;2, at the same time, the input signal of the PLC (especially from the welder) must be isolated;3, PLC output to the welding machine parts have to be isolated by relay;4, select the appropriate PLC, design and installation wiring should be standardized.
Q:Why does the argon arc welding machine burn the black stick?
Why does the argon arc welding machine burn the black stick?:1: gas has problems. Impurity, air, air leak.2: there is a problem with tungsten bar. The quality is poor and the diameter is too small.The 3: machine has problems. The rectifier is burned and has a reverse discharge.4: earthing wire is connected.5 、 large current selection,6, tungsten needle from the dissolution pool too close to the loss,7, select the appropriate current, suitable diameter tungsten needle, the operation of the tip of the hour from the dissolution pool position.
Q:Inverter type argon arc welding machine can not be welded without squeaking sound
The ground line is broken or the inside of the torch is broken
