This could be dangerous if you aren't very careful. Take the transformer out of the welding machine. Put it on a wooden bench. Apply 12 volts to the input side with a car battery. Measure the input volts with a volt meter and write down the value. Then use your volt meter to measure the output voltage. If you have no output voltage then your transformer is obviously blown. You should read an output voltage that is higher than the input voltage based on the number of winding in the coil and/or the manufacturers specifications. According to Faraday's law the only output voltage you will read is at the exact time power is applied to or taken away from the input when using dc power. Otherwise you will have to apply ac power which is much more powerful ( and more dangerous ) than the 12v dc. Your volt meter may not be designed to read high enough voltage for the output you would see with 110 v ac.

What kind of experience do I need to be a welder?
According to my research in order to become a Welder you will need to take a test to receive your Welder's certificate. Once you get the certificate you can apply for jobs.
Why the open and short ckt test of transformer is needed?
The open/short-circuit test on a transformer isn't 'needed'. It's only used if you want to find out the efficiency of a transformer.
What type of test is required for welder performance qualification?
bend test visual examination radiographic test all of the above
What is the use of back to back test in transformer?
Back to back test give data for finding the regulation , efficiency and heating under load condition. Back to back test is performed in the presence of two identical transformer. In this test one transformer remains open and other remains loaded. Hence sumpner's back to back test is generalised form of o/c test and s/c test which is performed within one test only. Hence from this test we find core loss and full load copper loss simultaneously at a time.
Can a high voltage transformer be megged with a megger meter?
No. A megger's output voltage is not high enough to test the insulation of a high-voltage transformer if, by 'high-voltage transformer ', you mean a distribution transformer or power transformer. Instead, a high-voltage test set or 'pressure tester' (e.g. a 'HiPot' tester) must be used, as these produce far higher voltages.
What is dielectric test in transformer?
why need dielectric test for transformer
How you can use your 110v arc welder on 220v country?
You will need a 'step up transformer' but it is important to provide the details on the information panel of the welder before ordering
How will be conduct test on transformer?
Short circuit test and open circuit test are widely used to test the efficiency of the transformer.
What is the difference between an arc welder and a stick welder?
Stick welding is also more difficult to learn and use, particularly the ability to strike and maintain an arc. Arc welders are available in AC, DC or AC/DC, with AC being the most economical. It's used for welding thicker metals of 1/16 inch or greater.
What are the purposes of performing no load test for the transformer?
These two tests are performed on a transformer to determine (i) equivalent circuit of transformer(ii)voltage regulation of transformer(iii) efficiency of transformer. The power required for theseOpen Circuit test and Short Circuit test on transformeris equal to the power loss occurring in the transformer.
Why do we need a transformer if we use a welding machine?
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 kind of experience do I need to be a welder?
According to my research in order to become a Welder you will need to take a test to receive your Welder's certificate. Once you get the certificate you can apply for jobs.
What is the difference betweenTig wire stick welder?
a stick welder needs to replace his electrode regularly and the flux coating is on the outside while a tig machine constantly feeds the wire and the flux is produced by a filler gas
If Three welder's are welding on one test coupon different filler wire and different welding processes after radiography one welder has failed.what about other welder he also will fails or not?
The other welder will also fail.
Why the open and short ckt test of transformer is needed?
The open/short-circuit test on a transformer isn't 'needed'. It's only used if you want to find out the efficiency of a transformer.
What type of test is required for welder performance qualification?
bend test visual examination radiographic test all of the above
What is the purpose of conducting sc and oc test of single phase transformer?
to determine the transformer characteristics...
