A welder requires high current at the expense of voltage, The transformer reduces the voltage allowing a higher current to operate the welsing machine.

What is rectifier welding machine?

A welding rectifier takes in the a/c output of a welding transformer, and the output is d/c. Used with old school welding transformers which were all a/c, in order to get d/c for use with low hydrogen rods etc.


When to use dc welding machine and ac welding machine?

Dc welding can be used for non consumable electrodes with consumable electrode heat is transferred from electrode to work by molten metal. Ac welding is desirable for aluminum and magnesium, because it helps break up oxides AC is more stable than Dc.


Can you use transformer for DC supply?

No. Only Transformer could not be used for DC supply.If yoy need to have DC out put,then rectifier unit required .


What is the application of pluse transformer?

why should we use pulse transformer rather than ordinary transformer


Why is a transformer necessary?

A transformer is not 'necessary'. The human race evolved, and developed cultures, societies, disease resistance, and technology, without ever seeing a transformer. But there are specific situations in which desirable things can be accomplished much more effectively and efficiently with a transformer than with any other device or method. Here are a couple of examples: -- If the voltage you have available is not the voltage you need, then you can use a transformer to make the change. (But that only works for AC.) -- You can use a transformer to change the output impedance of an amplifier to the impedance of the speaker or earbuds you want to use with it.

Can you use Stick Welding machine for Spot Welding if yes how?

They sell a spot welding gun that plugs into a DC arc welder. If you have an AC225 or some other AC-only machine, this won't work. In general, tho, spot welders have their own power supplies so you don't need to reconfigure your stick welding machine for this.

What is the purpose of a transformer?

It steps down voltage by moving the iron core spacing. Mostly using on high current welding transformer. Easy to achieve changing output voltageand does not need to use high power selector to switch voltage

How do you use my US washing machine 120 Volts 12 A 60 Hz in the Philippines?

You would need a transformer - to change the Philippines voltage to that of your washing machine.


What type of welding machine use in spot welding or resistance welding?

Mainly In spot welding & resistance welding two type welding machines are used :- 1. Air Cooled & 2. water Cooled.


What is the material of the transformer of stationary spot welding machine?

The core of of the transformer is either iron or some special alloys of mild steel - the primary and secondary windings are normally copper although some vendors use aluminum - the latter normally results in transformers that are larger in physical size, but lighter.


how does laser welding machine work๏ผŸ?

The welding process of laser welding is very similar to the traditional MIG TIG (arc welding) welding process. However, in contrast to MIG, TIG welding, Laser welding is much cleaner than conventional arc or Tig welding, and thus helping to reduce the risk of contamination. It's also more precise, easier to automate, and provides for bonding of much thinner metals, and provides for much greater tensile and bending strength. Laser welding is a process that uses a laser beam to join metals or thermoplastics together to form a weld seam. As such a concentrated heat source, laser welding can be performed at ultra-fast welding speeds in thin materials, while narrow, deep welds can be produced between square-edged parts in thicker materials. Often one would use a wire feeder from a laser welding machine supplier to fill the weld seam. how to use laser welding machine Since laser welding machine is different from MIG and TIG, the operation of laser welding machine is the simplest. Usually, MIG, TIG, and other welding processes require a welder who is very familiar with the welding technique to operate. Unlike laser welding machines, you only need to set the parameters needed for the laser to penetrate the surface, and you can use the parameters set at that time without changing the thickness of the material in the future. There are almost no consumables for laser welding machines, but the more common ones are gases, lenses, and copper nozzles. Lenses and copper nozzles are usually included by the laser welding machine supplier when the machine is packaged. These are enough to last for many years. Laser welding machine production methods and costs, accessories. The laser welding machine is basically composed of optical components ( There are galvanometer, beam expander, field lense and other important optical devices in the optical path system of the laser welding machine.), laser welding head, automatic wire feeder, control board (laser welding machine control system), laser generator and so on. The YAG laser welding machine will also include the YAG laser generator (yttrium aluminum garnet crystal).


Can a US sewing machine be used in UK?

The voltage in a UK outlet is about twice that of a US outlet, which means you could ruin your sewing machine trying to plug it in. In order to use your US sewing machine in the UK, you'll need to purchase a voltage converter (transformer), and then you'll need to buy a UK adapter (since the transformer plug doesn't match UK outlets).
