Can a microwave transformer be used for other purposes?

Click For Summary
SUMMARY

Microwave transformers (MoT) can be repurposed for various applications, including car battery chargers and arc welders. However, they pose significant safety risks due to their ability to output medium voltage (approximately 2000 volts) and high current (around 550 mA), which can be lethal at levels above 50 mA. Users must exercise extreme caution and possess a strong understanding of electrical systems before attempting to utilize MoTs for alternative purposes.

PREREQUISITES
  • Understanding of electrical safety protocols
  • Familiarity with transformer operation and specifications
  • Knowledge of AC voltage applications
  • Experience with high-voltage equipment handling
NEXT STEPS
  • Research safety measures for working with high-voltage transformers
  • Learn about the design and functionality of arc welders
  • Explore the process of converting microwave transformers for battery charging
  • Investigate forums and discussions on microwave transformer applications
USEFUL FOR

This discussion is beneficial for electrical engineers, hobbyists interested in DIY electronics, and anyone considering repurposing microwave transformers for practical applications while prioritizing safety.

I have the transformer from a microwave that has the few turns and big windings on one side and the other side must have smaller turns I was just wondering if you apply 115 volt ac to the larger number of windings what would come out the heavier windings? I am just wondering if this can be used as a car battery charger or arc welder or any other use before I take it apart?

MoT can be used for a number of things but I must caution you, they are dangerous. You can kill yourself playing around with them so I always suggest people that are not extremely familiar with electricity to stay away from them.

To clarify, MoT are dangerous because they put out medium voltage (~2000 volts or so, depending on the model) with high current (~550 mA or so, depending on the model.)

The number of mA it takes to kill you depends on a number of things, but if I recall correctly 50 mA or higher can be lethal.

Another edit to link you to a thread I just found by using google. It's a 3 page discussion of MoT.
