Q:i have one traditional old mig welder with transformer and i would like to buy one inverter mig wilder because its lighter weight,so which is better in working and less trouble?: Inverter Mig Welder

Q:How do I choose a transformer? The: According to the nature and size of the load to determine the capacity of the transformer. The ratio is selected according to the supply voltage and the voltage required for the load.

Q:Usually the life of the transformer is called 20 years, is there any GB requirements? If there is a specific in that standard inside. Thank you for your thanks: I can only give you in the transformer industry, we all agree that the argument: 1, before the transformer, the oil inside the transformer and air direct contact. As the transformer in the thermal expansion and contraction, the oil up and down fluctuations, we called the transformer in the breath, an increase of oil and air contact opportunities. The moisture enters the inside of the transformer. So that insulation is reduced. Under normal operation and maintenance, the transformer is guaranteed to have a life span of 20 years. 2, the current transformer, to take a fully sealed structure, oil pillow with sealed pocket, so that the transformer oil is not in direct contact with the air. Under normal operation and maintenance, the transformer life is 30 years

Q:How do I select a transformer connection group?: Connection group can not be arbitrarily selected, depending on the primary transformer connection group. If the higher-level transformer for the star angle, the next level on the election star angle

Q:By applying ohms law in the secondary circuit, IV(stepped up)/R , a stepped up voltage would result in an increase of current, i am aware that the step up transformer steps down current, but it is the secondary circuit that determines the current draws (ohm's law), and the primary current is multiples of itSo ?!!!!: Transformer coils are electrically isolated, the voltage in the secondary being induced by that in the primary. There is therefore no constant current between. The POWER (WAV) in the primary has to have an an induced equal counterpart in the secondary. In this case, as the voltage in the secondary is larger, the current drops proportionally. At the end of the transmission line it's stepped down again, and then you get a current.

Q:Transformer short-circuit impedance is big good, or small good? The same capacity, voltage ... solution: Can not simply say big or small good because of the big, in the normal operation of the loss of certain size, in the short circuit. Short-circuit current will be great, less investment protection equipment corresponding to the requirements of the money so much to be more economic comparison Caixing! Can not be generalized, the choice of different transformers, impedance voltage is not the same; national transformer standard series, the general 10KV distribution transformer impedance of more than 5%, 35KV transformer impedance of more than 8%, 110KV transformer impedance In the 10% or so, the greater the capacity, the greater the impedance; transformer impedance increases, you can effectively reduce the size of short-circuit current, so in high voltage, high-capacity transformers, multi-purpose high-impedance or series reactor To reduce the short-circuit current, or some equipment is not a good choice; but the transformer impedance increases, the transformer will increase the volume, material consumption increases, the transformer running loss increases, but also to reduce the transformer secondary voltage, Is the transformer overload, the voltage will quickly decline, in case of short circuit conditions, may cause other equipment, low voltage action; under normal circumstances, or use the standard design of the transformer products, unless the special needs, do not use non-standard products, or in the Transformer side by side, selection, testing, maintenance, replacement will cause additional trouble.

Q:I have 3 transformers that for some reason burned-out . I say burned- out because that's what it smelled like when they stopped working. If you have a reason why this is happening please include with your instructions on how to repair them if it's possible. These transformers are 120v input ,12v output. Thank You RE: If you put the wrong bulb in they can burn out. You say it's a 12 volt system. There are different wattages, and if you put too high a wattage you will cook the transformer. No, you can't repair them. Not unless you have the machinery to delaminate the metal core, unwind and rewind new copper coils. You COULD do it by hand, but by the time you've gotten it done, the time you wasted could have been spent working and earning a buck to replace the lamps. Make sure you're not going OVER the wattage specified. Here's some numbers: 12 (volts) times X (amps) equals W (wattage). If the transformer tells you it puts out 12 volts at 3300 ma (mili-amps) (or 3.3 amps) then 12 X 3.3 equals 40 (Watts). If your transformer is designed to operate a 40 watt bulb then it must be capable of putting out 3.3 amps. If it's half the wattage, say - 20 watts: 20 / 12 1.67 (amps). Knowing the capabilities of the supply and not demanding more of it than it's rated for will prevent it from smoking (burning out). Hope this helped. '')

Q:What is the main purpose of the transformer?: If the secondary connected to the load, the secondary coil to generate current I2, and thus produce magnetic flux ф2, ф2 and ф1 opposite the direction, played a mutual offset effect, so that the total magnetic flux in the core has been reduced, so that the primary Self-induced voltage E1 reduced, the result is I1 increase, showing the primary current and secondary load are closely related. When the secondary load current increases when I1 increases, ф1 also increases, and ф1 increase part of the part is just to be replaced by ф2 that part of the magnetic flux to keep the total magnetic flux in the core unchanged. If you do not consider the loss of the transformer, you can think of an ideal transformer secondary load power consumption is the primary power from the power supply. The transformer can change the secondary voltage by changing the number of turns of the secondary coil as needed, but can not change the power that allows the load to be consumed.

Q:As a small project I wish to wire a microwave transformer to create arcs in air via use of a wand (and yes I will be taking the necessary precautions but that's step 2) first I need to know a couple things: 1 on the high voltage secondary is it really as simple as take the two leads and put them anywhere near eachother? Would that not create a MASSIVE short circuit? Most of the tutorials I've seen use in series so perhaps that negates it in some way? Or am I reading it wrong? Is there some sort of safe load used? Or does it really arc to itself? And 2 what is a good way of preventing it from overheating (if that is a problem). This will probably be used as a Jacob's ladder or old motherboard destroyer. Thanks so much for the help!: Don't.

Q:I love the Transformers movies and games to death, but I've never ever been able to like the cartoons.I know they were somewhat popular, especially as the first Transformers game was a huge successplease add why you like/dislike it.thanks in advance: I loved the original Transformers' cartoon. Optimus Prime was the ultimate good guy and Megatron the paramount bad guy. No matter the odds the Autobots never gave up. Some of the coolest characters were Autobots and Decepticons. The Dinobots were just freaking cool and I always like Soundwave. The only reason the movies even had a chance of success was that they brought back the original voice of Optimus Prime. Optimus dying was a shock to be sure, but they still did a good job without him for awhile. I have happily introduced my son and daughter to the original series and they both liked it more than the new movies. It is okay you don't like the original cartoons. They aren't everyone's cup of tea.
