Q:What's the reason for this? Tell me about the trouble. I work in argon arc welding, the novice today, dry with a dry suddenly broken, the arc, I thought is a switch or circuit which is broken, later discovered, with tungsten tip with the welding surface contact, causes a spark. What are the reasons for seeking advice?.

First of all, to see if you hit the welding gear, try another gear,If not, check that the high frequency part is faulty,Arcing indicates that the main circuit is not broken

Q:Excuse me: how about the power of 315 DC arc welding machine?

315 welding machine general election 100A--250A, work voltage is 38V, three welding machine work at the same time the maximum power: 250*38*3=31 kW, select 35 kW generator enough.Welding machine is a kind of electric power supply which provides certain characteristic for welding. The common welding machine has three kinds of direct current, alternating current and pulse from welding current, but AC and DC inverter welding machine are often used. The main component of the electric welding machine is a step-down transformer. The two ends of the secondary coil are welded workpieces and welding electrodes. When the work is done, the arc is ignited, and the electrode is fused into the gap of the workpiece at the high temperature of the arc.

Q:There are several argon arc welding machines in our factory. There is a problem with it. To put it plainly, sometimes it can lead to arc. Sometimes it is very close and can not arc. Abnormal welding. Come on, master!

1: high frequency plate aging, high frequency ignition ability is reduced. Continuous welding does not require repeated arc striking, and arcing is difficult when arc welding is broken. The problem can only be solved by replacing the new high frequency board.2: high frequency plate put point electrode gap is not, or burning serious, with fine sandpaper or gauze lightly grinding discharge electrode, re installed. Severe burning and replacement of new electrode when necessary.3: continuous high current welding, argon flow is smaller. Tungsten oxide oxidation. The oxidized tungsten electrode affects the electrical conductivity, and the arc breaking spot welding also affects the arc initiation performance. Continuous arc welding does not require repeated arcing, and no arcing phenomenon can occur. Increase argon flow according to welding process.

Q:Welding aluminum parts by argon arc welding, I made a control cabinet, servo motor to drive the welding torch to move, and control welding current, control welding stop,There are 2 servo motors in the cabinet,.1 PLC. When I arc, the high frequency of the welding machine will affect my welding machine, and the servo motor will run around,PLC the first second inputs X1.X2 will flash. When the control panel is out of power, the welder will start arcing, and the alarm light on my Cabinet will flash (no power is on)The alarm beeps, too. Put awayA filter in front of my PLC with the servo driver, but the driver in front of hell no isolation transformer, alarm lamp in front of no isolation transformer, servo driver CN1 input port with no shielding line

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:What accessories does argon arc welding machine need?

An argon arc welding machine, with parts of the manual, wire, welding wire, welding torch mouth (copper mouth and porcelain mouth), tungsten pole, and the need to buy an argon gas pipe, a length of its own, argon meter, argon cylinder one.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:What kind of antifreeze is used in water-cooled argon arc welding machine in winter?

Anti freezing cooling fluid for automobile, it can be used in water cooled arc welding gun in winter.

Q:What kind of argon arc welding machine is used is manual welding and argon arc welding switch? What's the connection between direct current and pulse? The more detailed the better, for example, when to switch to manual welding, when the use of argon arc welding, when the use of DC or pulse, how they match, and so on. ThanksAlso, what are the main aspects of direct current argon arc welding? What's welding? What are the main uses of pulse argon arc welding? What's welding? Is manual welding direct current or pulse? What's the main weld? Manual welding is not the kind of electrode welding?

This is your welding machine DC welding machine, it has two kinds of manual welding and argon arc welding, manual welding is the welding, soldering or welding can, stainless steel, argon arc welding can also iron welding of stainless steel. A pulse is in the welding process, as is your pulse, jump when welding, when the jump is not welding, when you press the switch, it will fire pounding, in fact it is working in high current low current, high current work. Then, low current work, continuous circulation, circulation speed can be fast or slow, you should adjust current regulation of the highest and the lowest current switch, you let it stop. The general pulse is used to burn automatic welding, the welding effect scales with more. Here you don't actually mean DC pulse, you switch it by welding, it will not upset the meaning of welding switch.

Q:I can not ask TIG welding soldering iron?

Of course, the most popular is the dream of welding, soldering iron

Q:Pondering over this afternoon for a long time, that is, welding can not, and welding a little hard on the break, we set the 120-140A current, argon flow of about 1. We want to be the parameter is wrong, just don't know how to adjust, ask the welding master to answer,

You can adjust the use of welding needle is the problem, to sharpen, flat welding, face to face, welding needle and porcelain mouth flat or concave into a little,When the welding angle is included, the welding needle protrudes 1 millimeters of the porcelain mouth, grasps the degree, and also releases the stuck gas before releasing the welding by pressing the hand switchWelding the workpiece again, the current can be a little bit bigger, 160A, a little bit, you will do it

Q:My existing AC arc welding machine is 200 of the power is too small, I would like to put the home of a 400 AC welder with 200 AC arc welding machine together, do not know whether it is good to change, please experts advice, thank you!

Your question is a bit difficult ah, because the AC motor, no two tablets, you have another machine, but he can only use a machine work rate, even if you add, also can make the electric welder two burn out of your heart
