2. Rigorous process design, regardless of harsh environments or reload will operate properly

3. End voltage and current adjustable, regulate that help to make up the crater defects at the end of welding

4. With voltage and current adjusted separately/simple synergic function, whether newbies or skilled welders can easily operate.

Tips: If welding cable is longer than 5m, dual-driven wire feeder will be a better choice to reach better welding performance.

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!: 1, can be directly connected to the argon arc welding torch, of course, have to connect the gas road, the current to the desired position, the line of arc (that is, contact short circuit, arc), direct welding can be2, note: welding torch negative electrode

Q: What are the well-known automatic argon arc welding machines in the world?: They are all foreigners. Funes. Issa, Ken, Miller. Lincoln. Mega Nick. And has made the sun. Times. Wtl. Welding research and technology, Hua Heng, huayuan. Wait

Q: There are several kinds of arc welding machine, argon arc welding machine and several kinds. What are their occupational hazards?: Manual arc weldingArgon tungsten arc weldingCarbon dioxide gas shielded arc weldingsubmerged arc weldingmetal inert-gas welding

Q: What brand of portable argon arc welding machine is good?: Of course, imported Panasonic, Lincoln, Miller, OTC, and Issa are good.Domestic sales of the largest civilian reallink minicomputer.One of the best industrial machine era, okuta.The rest of the welding machines are basically imitating the above ones.

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: Which is good for mould argon arc welding machine Ws and TIG?: WS easy to useTIG refers to low-power tungsten arc welding such as TIG-160, TIG180, TIG-200 and so on. Civil small batch work can be used.WS refers to the power of non consumable (Wu Ji) inert gas shielded arc welding, argon can be used, you can also use other inert gas, power, multi-function, used for pipeline backing welding, pressure vessel welding backing, non-ferrous metal welding, or other important structures..

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 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: What argon arc welding machine is used in the circulating water tank of the welding truck? Copper and aluminum water tanks: WSME-250 welder is enough.Select welding process according to metal material of water tank.The copper water tank can be welded by Direct Current TIG welding.The aluminium alloy water tank is welded with a pulsed AC TIG welder.Because the water tank material is thin, the use of pulse gear can not only ensure adequate input, such as avoiding welding current is too small, welding seam and base metal fusion is bad, porosity, cracks, not fusion, welding and other defects. It can also prevent burning due to excessive welding current.Pulse welding of the entire bath after stirring, not only weld forming beautiful, but the weld strength is much higher than the ordinary constant current welding

Q: Do you have argon arc welding machine without cylinders? I welded stainless steel pots and basins: Argon arc welding machine can't do without argon, but you can make a larger rubber bag with valve, and pour some argon into the bottleSon, when used in the bag: something, you can use Zhang time.Argon is an inert gas, and there is no danger.
