Q:Can the DC welder be used as an argon arc welding machine?
The DC welder can not be used as an argon arc welding machine.DC welding machine, in broad sense, as long as the output is direct current, belong to DC welder.Including two welding electrodes, hand arc welding, DC TIG welding machine, etc..Narrow sense, DC welding machine is: welding rod hand arc welding machine.Only welding rod arc welding machine, using strike arc, can be used as simple tungsten argon arc welding, the disadvantage is that the need for external gas control system. The larger the short-circuit current is, the more serious the tungsten electrode burns. The weld is easy to clamp tungsten.
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:How does the argon arc welder overheat protection?
Let's have a rest when it's hot.Dust the welding machine.Change it to a larger welder.
Q:Can argon tungsten arc welding be regarded as manual arc welding machine?
Argon tungsten arc welding argon tungsten arc welding support dual function electrode arc welding, TIG welding can be welding rod arc welding stall switch arc welding position of electrode arc welding welding operation.Single tungsten argon arc welding machine can not be used for electrode arc welding. The two principles work differently.Tungsten arc welding usually uses high frequency arc ignition, lower working voltage to reduce electrode (tungsten) burning;The electrode hand welding adopts the short circuit arc striking (striking, striking or striking the arc), which needs relatively high welding voltage, melting electrode (welding rod) for welding.
Q:How can the ordinary invert direct current welding machine be changed into argon arc welding?
Hello. This problem is rather difficult. It costs too much to change the machine. Therefore. Now there's a gun. Mainly for you such users. This kind of gun is on the market now. You can buy the parts where the welder parts are purchased. We call this kind of gun called cross valve. A gun with a valve can switch to control the argon size.
Q:What about the current of argon arc welding machine is too small?
Argon arc welding welding current adjusting welding current of TIG welding is usually chosen according to the space position of the workpiece material, thickness and joint, when the welding current is added, the penetration depth increases, the weld bead width and height increased slightly, but little increase, the welding current is too large or too small will cause the poor weld shape or welding defects, the position of the welding current to 80 ~ 110A is better, the ideal current value is 90A, when the spot welding current to 150 ~ 180A is better, the ideal current value is 160A.
Q:Why does the argon arc welding machine burn the black stick?
The current selection is large, the tungsten needle is too close to the dissolution bath, and the suitable current is selected. The tungsten needle with suitable diameter is operated with an hour head and a proper distance from the dissolving bath, and the speed is right
Q:What brand of argon arc welding machine is of good quality?
To solder aluminum, the general welding machine or model is difficult to achieve good welding effect, technical requirements are higher. Still, this time choose Aotai welding quality and relatively high visibility. As for those small cards do not suggest that you buy, generally difficult to effect, but also delay the construction period. Our factory has encountered such a situation, then buy the okuta welding machine, the welding quality and reliability are also 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: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.
