Ever put a new blade on and then broke it on the first or second cut for some reason? Do not throw it away!! All you need is a tig, some copper plate, brazing tip on your torch and some mig wire. Remove any coatings from the break area, clamp it down on the copper plate, set the tig low DC neg and weld it up with your er70-s. let it cool down a bit and then anneal it gently with the brazing tip. Get a sanding pad and grind your weld flush. If you do it right it will be good as new except for a tooth or two where you welded it up. If you want to buy blades in rolls you can sure save some money this way.
