Q:Argon arc welding machine does not arc, what is the reason ah?
Argon arc welding arc is largely because of there is an internal arc electrode gap caused by the machine shell, open can see, generally in the high voltage side, you can first use fine sandpaper, if not put the gap down, then the internal dust too much, need to clean up. No longer is the original problem, direct repair
Q:Can the WS series inverter argon arc welding machine be cut?
Can not. Cutting requires LGK or CUT series air plasma cutting machine.W: (tungsten) tungsten, the initial letter of tungsten. Representative: tungsten pole (Ya Huhan).S: (hand) worker, the first letter of the hand. Representative: hand welding (hand arc welding, welding rod arc welding).WS welding machine is: TIG welding arc welding welding machine. Only for hand arc welding of electrode, TIG welding.
Q:Reallink Christie and argon arc welding machine which is good, what are the advantages
Reallink, Christie, which is a company of the two brands, as well as dacentrurus.Later the brothers go out, put out the brand christie.I especially love Christie, Christie treasure series.
Q:What brand of argon arc welding machine is better?
Lincoln's argon arc welding is the best in the world. The model is based on the material and thickness of the material to be welded, as well as the size of the welding and the quality requirements of the welding.If you can tell me exactly what you weld, I can recommend the right model to you.
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
Reason:High frequency electricity, pay attention to cleaning the dirt at the interface, arc when the tungsten is not too far away from the workpiece.High frequency electricity:The high frequency current is the current relative to the power frequency 50HZ alternating current. For example, the carrier current in a communication signal is a high frequency current. In some cases, in order to change the speed of the motor, it is necessary to use a converter to change the power frequency current into a relatively high frequency current, also called a high-frequency current. High frequency currents sometimes have an obvious radiation effect and can even cause harm to humans. Of course, some less powerful high-frequency currents do no harm to the human body. One important characteristic of high frequency currents is the skin effect, such as a solid conductor, which usually runs on its surface instead of the entire conductor. In comparison with the power frequency current, a characteristic of the high-frequency current is that the fatality rate will decrease after the electric shock, and the higher the frequency, the lower the fatality rate. The alternating current above 20000 Hz is a high frequency current.
Q:Argon arc welding machine on the ignition, note: switch is not bad, what is the matter?
The high frequency part bad is not possible. You see there is no short circuit switch line. If not. You find the switch line socket next to a four relay. On the circuit board. Try to tap off. Whether arc. Trouble is the two. This is actually a little problem. You switch control part caused by short circuit at normal arcs. The current size adjustment. To prove that the machine main parts and high frequency parts are good.
Q:Argon arc welding fan cooling fan does not turn
The ship type switch is connected directly to a fan to supply power to the fan.
Q:Can ordinary argon arc welding machine not weld aluminum alloy? Why?
Ordinary argon arc welding machine can not be welded Aluminum Alloy, because Aluminum Alloy welding is the need to have a function of the cathode is broken, but the common DC argon arc welding machine is the function, does not have the function of communication so I do not have the function of broken cathode.The theory of ordinary argon arc welding of DCRP welding can be Aluminum Alloy, but the effect is very poor, easy to collapse and forming oxide matrix, are more difficult to forming good.
Q:Argon arc welding machine does not arc, protection lamp is bright
When the machine is turned on, protect the light, or press the gun to protect the light. Boot protection light, MOS pipe may be broken. Just above the board. Turn on the gun and protect it. Maybe the rectifier diode is out of order. It is also possible that the transient diode is out of order. There is also the protection caused by leakage of high frequency. Take the place where the welder is repaired. It's not expensive to fix it in a small machine
Q:I want to buy Christie Bao WSE200P AC DC pulse argon arc welding machine, but do not know how about the quality?
Christie, no treasure.Christie's treasure is a dedicated machine, is the electrode.The price is OK, it's a pity for 220 volts.This kind of tall, low, low, not low, very uncomfortable.Only suitable for small factories, less welding, less capital, more than one machine.Remember to pull a single power line 4 square, open 32.
