Hey folks,
I built a homemade spot welder using some parts i had around. The design intent was to use a push button to turn on a mosfet, and then quickly use two electrodes to spot weld a nickel strip. Unfortunately, my circuits is pretty rusty. I have built the circuit and attached schematic picture.
I am using:
Pushbutton SPST, 12 V 10 A rated: https://www.princessauto.com/en/detail/12v-10a-push-button-starter-switch/A-p8802654e
Mosfet as the power switch: https://cdn.sparkfun.com/datasheets/Components/General/FQP30N06L.pd
12V car battery
For the first test, the mosfet exploded and it seemed like the push button was staying on. Is this the wrong kind of push button to use, is my mosfet not rated/wired properly.
Any advice folks?
