Q:What is the problem of inverter type hand arc welding machine without arcing?
Check the following possible: diode bad, circuit board bad, power supply phase missing, power supply insurance burned, the template is bad.
Q:Can argon arc welding machine be cut?
Hello! Argon arc welding machine, namely 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. Argon arc welding machine is divided into two kinds of argon arc welding machine and non melting argon arc welding machine according to the different electrodes. The working principle of argon arc welding machine in the main circuit, auxiliary power supply, drive circuit and protection circuit is the same as that of the hand arc welding machine. No further description is given here, but the special control function and arc starting circuit function of argon arc welding machine are emphatically introduced.
Q:The length of wire on the two side of arc welding machine shall not be more than several meters
The longer the fever rises. So it's better to lengthen the side.
Q:Argon arc welding machine starting indicator light is not bright, fan turn is how, can not welding
Check the circuit
Q:How can common argon arc welding machine weld aluminum?
If there is no requirement for the welding seam, it is better to use AC argon arc welding machine instead of direct current reverse welding.
Q:Why does the argon arc welding machine burn the black stick?
There are many reasons for tungsten burning:1, check and between tungsten argon arc welding torch position: clearance clamping with the clamping seat or between the gun body is too large, if it leads to poor conductivity, when in lighting, too close to the metal, the instantaneous current greatly, concentrated heat, not only will stick the needle, and will lead to loss; in addition, position is not correct, will lead to poor cooling, can also cause damage. So try to tighten the cap and check whether the tungsten electrode is reliably fixed. When purchasing, it is necessary to choose a closer clamping and clamping seat.2, check whether the standard AR (four 9 standard, namely the purity of argon must reach 99.99% or above), if the argon impure, cause of tungsten inadequate protection, easy burning; in addition to check whether the leak; one of the factors also affect the quality of tungsten.3, according to the welding machine AC and DC to correct wiring.(1) if it is a direct current welding machine, the ground wire is connected to the positive pole, the welding torch is connected to the negative pole; if the connection is reversed, the tungsten electrode is burnt out;(2) if AC and DC welding machines are used, the burning of tungsten will be more serious in the case of ac;
Q:Argon arc welding machine automatic leakage, how to repair?
Could you explain in detail where the leak is?
Q:What is the principle of using gas in argon arc welding machine fast?
First of all, your gas cylinder does not change too much. Whether the gas discharge welding machine controls or not depends on the size of the gas bottle. When welding, the argon gas transmission does not need to be too large, and a little bit of air will do;Check each section of the trachea is broken, the general welding torch of the two joints, as well as the middle often bent, or often foot of the place, easy to break, leak;If there is a delay gas switch, to extend the air. Had a little effect on the air.There's nothing else to look for!!!
Q:Can the inverter DC argon arc welding machine be used without argon?
Be sure to use argon. If you don't use the seam, there will be air holes
Q:The difference and characteristics of AC arc welding machine and DC arc welding machine
Inverter DC argon arc welding machine is a non welding gas shielded welding machine. It uses argon as protective gas and tungsten needle as electrode welding machine. It mainly welds stainless steel, copper, magnesium and other insoluble metals. Inverter DC arc welding machine, welding machine DC welding by manual welding machine, it is not an ordinary DC welding machine AC arc welding machine. The price is more expensive.
