Hey guys - crazy question. Trying to figure out a quicker easier way to de-magnteize some parts that I had machined. They were machined on a magnetic base table so they have become magnetized. I read that you can de-magnetize with heat (very hot, too hot for these parts), hammering (out, I need to preserve the finish on these), or AC current. The only thing I could think of that had decent AC generation was my TIG welder lol.Could I hit my TIG welder to these steel pieces just to let it flail the arc around on the non critical surfaces to de-magnetize? Or, does it require the AC magnetic field of an AC source? Bah!Any ideas?Miller Diversion 180Hobart Handler 140 (Soon to be replaced with Miller 211?)Miller Spectrum 625 Extreme
Reply:Find or make a degaussing coil like the ones they used on CRT tv sets before the sets had the coil built in. Or, find a bulk magnetic tape eraser which does the same thing but was made for use on open reel tapes.PapaLincoln Idealarc 250 (circa 1962)Lincoln Weldpak 155 w/Mig KitLincoln Squarewave TIG 175
Reply:Several years ago I was able to degause a large CRT monitor with a Weller soldering gun. I just turned the gun on and passed it slowly around the monitor about an inch or two from the screen for 2-3 min. It worked like a charm.I don't know if it would work for your problem but its worth a try.Bob
Reply:They have de magnetizer's usually in the shop were the do surface grindingcause you do that right after your done grinding the partI always hated that thing because of the 60 cycle hum it gives off ...been shocked one to many timesBacked my CATMA over your CARMA oops clusmy me What would SATAN do ??
