i want to know about welding transformer its working,constrution in text format?

A transformer style welding machine converts the high voltage and low current electricity from the utility into a high current and low voltage, typically between 17 to 45 volts and 190 to 590 amps. This type of machine typically allows the welder to select the output current by either moving the core of the transformer in and out of the magnetic field or by allowing the welder to select from a set of taps on the transformer. These machines are typically the least expensive to purchase for hobbyist use.

Well, this may not be an animation, but it is a pretty darn good online text covering introductory electrical engineering concepts.\n\nhttp://www.ibiblio.org/obp/electricCircuits/

The best publication and industry engineering guide is \n"The J&P Transformer Book" available through most on line bookstores. It is pricy by is the best text book on transformers\nSource: Electrical Engineer (ret) with 45+ yrs experience

For the text box that will contain the RTF data - select Format Field ... then on the Paragraph tab change the Text Interpretation to "RTF Text" - that should display the data as RTF ... good luck!

Attach the earth cable of the welding machine to the ship's hull, and attach the job you are welding also to the ship's hull. The current will flow through the steel structure of the hull.\nOtherwise you can attach the earth cable of the welding machine directly to the job you are welding, if they are close together.

Yupp... but unfortunately is a hardcopy on my desk. Perhaps you may straight to tell us what\n\n1. You are designing from HT to Transformer 11kV / 415V\n2. You are designinig from Transformer to LV ??\n3. What is the kVA of the transfomer?

It has been years since I have made transformers, but look up Stangenes Industries in Mountain View, California.  They may help directly or know who can.  I was building YaG laser power supplies with some custom trigger transformers.  They reverse engineered one for me and it worked great.  They are high integrity and really do a good job.

In simple terms a transformer basically consists of inductances and not resistances . Also due to the concept of magnetic flux linkage coming into picture , ohms law cannot be used in transformers

1 amp (1000 millamps) is the maximum rated operating conditions for the transformer.  You may be able to get more current than that from the transformer, but the rest of its specifications (such as output voltage, operating temperature, efficiency, etc) are no longer guaranteed to be accurate.\n\nIt would be a good idea not to exceed this current draw if you want the transformer to last, and not pose a fire danger.  Consider using a fuse in your circuit to prevent overcurrent conditions.

Arc welding electrodes are identified using the A.W.S, (American Welding Society) numbering system and are made in sizes from 1/16 to 5/16 . An example would be a welding rod identified as an 1/8" E6011 electrode. \nThe electrode is 1/8" in diameter \n\nThe "E" stands for arc welding electrode. \n\nNext will be either a 4 or 5 digit number stamped on the electrode. The first two numbers of a 4 digit number and the first 3 digits of a 5 digit number indicate the minimum tensile strength (in thousands of pounds per square inch) of the weld that the rod will produce, stress relieved. Examples would be as follows: \n\nE60xx would have a tensile strength of 60,000 psi E110XX would be 110,000 psi \n\nThe next to last digit indicates the position the electrode can be used in. \n\nEXX1X is for use in all positions \nEXX2X is for use in flat and horizontal positions \nEXX3X is for flat welding\nThe last two digits together, indicate the type of coating on the electrode and the welding current the electrode can be used with. Such as DC straight, (DC -) DC reverse (DC+) or A.C.\n\n\nWelding Electrodes are wires or rods of metals or their alloys which are mainly used in welding. The primary purpose of using an electrode in welding is to maintain the arc needed for welding as well as supply the filler material at the point where the welding is done. It actually serves as a conductor for the current required to form the welding arc. The electrode may be consumed during the welding operation or may be just acting as a conductor. The metal electrode is mostly used as a cathode in direct current welding, whereas in alternating current welding the electrode is neither a cathode nor an anode.\n\n\n\nWelding Process \n\n\nA welding arc is created between the two metal pieces to be welded, using an electric power supply which can be either DC or AC. The power supply is so high that the arc created by it can melt the metal parts which form a part of the arc. If the electrode is the filler type, the arc created between the electrode and the base metal melts the electrode. The molten electrode serves at the filler material, enduring additional bondage between the welded parts. Additional filler materials and flux are used along with the electrodes to provide enhanced properties of the weld. Sometimes, even a special environment of a shielding gas is also provided to enhance the welding process.\n\n\n\nTypes of Welding Electrodes \n\n\nFactors which influence the classification of  welding electrodes are\n\n\n        Consumed electrode\n\n        Non-consumed electrode

go to a local welding shop and tell them what you need ...you just might want to take the thing to them so they can get an idea of what you are looking to get ... dont be cheap about it get your money's worth... you cant put a price on saftey

Create an enclosure around it. There are plenty of acoustically dampening cloths. Use fireproof materials only. \nAlso make sure that the enclosure is vented.\n\nAs a precaution, leave an air gap of around three or four inches around all surfaces of the transformer's outside metal box. Lastly dont let the air inside ever get hot.
