Thanks for the suggestion. I'm looking into it right now. But it looks as though those buck converter products can't handle over 2 amps, pic related. Seems some can do higher but they cost multiple times more. I found a forum and someone said they used a PWM to control their diy hot wire cutter. So I looked and I found this https://www.amazon.com/PEMENOL-Controller-Adjustable-Regulator-Generator/dp/B07WR4KBMF/ref=mp_s_a_1_4?keywords=12v+pwm&qid=1654764966&sr=8-4
Would this work? It says it's rated current is 5 amps. Not sure if that means input, output or both. Would my psu (14 amp max) kill it or would it just draw (not the max) 5 amps? (Idk how that works)
Do I just have to buy a 12v 5A power supply for it instead?
Also I'm assuming the negative terminal connects to ground since it's not ac right?
