Oh God how I hate those cheap ass red Chinese welding magnets and I am sure you do too! They always pack full of whatever slag is left on the floor and that renders the angles completely useless. You can never clean them out because the power of the magnet is enough to lock that shop shit into the groove for all eternity. Speaking of the power, the grip strength is so much that the magnet moves can move a carefully tack welded part when welding delicate parts. Then there is the angle...Man I dont think I have seen a single red magnet that is even close to the correct angle. Ive welded 90* joints that ended up more than 10* off thanks to Xi Jingpings little helper. Thats where the Mini Mag comes in. This baby has just the right amount of grip and a compact size for those small and delicate pieces of work. They can also be blown clean with simple shop air from your air compressor. The angles are 45* and 90* and CNC machined so you know they actually are the correct angle! I even added in a sweet little fillet so if you have an existing tack you can still use the magnet!
