WOYO 900W Rusty Nut Screw Remover Ductor Magnetic Induction Heater Kit Automotive Flameless Heat
A part of the review has been auto-translated.
Never had one of these before so I wasn't totally sure what I was getting into. I picked a medium size coil and a piece of random 3/8 all thread I had laying around, and in about 90 seconds or so, it was glowing red. I didn't stay on it too much longer, but it proved a point. How well will this work a year or 5 years from now, no idea. But it's half the price of the competition. If I were to make a change to it, I would reverse the air flow so instead of blowing it at you, it comes in the back where the air should theoretically cleaner, and blow it out the front to help move smoke from the glowing metal away vs sucking it into the gun. It has 3 preformed coils, and one flexible one for getting around objects with no break points, like a water pipe. Overall I am happy.
Super!! This one kills problems of rusty nuts and treads!
