How can I get my power supply to stop blowing fuses? Answered
I built a power supply using a 25.2 volt 2 amp transformer to use for etching projects. It worked on my test plate but then started blowing the 1 amp fuses I was using with it. I switched to 2 amp fuses and it works but my transformer is getting too hot. I have experimented with different amounts of solvent and different size plates, which definitely makes a difference, though my 1 amp fuses are at most lasting about 10 seconds. I have read about building a control box with a halogen light and a variable resistor to control the amperage, but would it allow me to take some of the load off of the transformer? And if it would work, how would I connect it to my power supply?
