If I've inspired you to get an angle grinder , I hope I can inspire you to use it safely :
-#1 rule with all power tools : safety glasses !! even better :a face shield.
-Grinders are 2 handed tools ! never , never ,never use it with one hand.I ain't kidding , I've fired people for this.
-Be very careful about getting the correct speed wheels for your grinder...I've seen what happens when you put a wheel not rated for the correct RPM onto a grinder : It explodes.....I've also seen the ambulance taking the guy to the hospital for said mistake...
-Wear gloves , and not just crappy gardening gloves , a grinder will go through those like it aint there.Best to invest in some 2 layer welding gloves.
-You might notice the 'guard' has been removed from my grinder.This is only because the wire brush doesnt work with it on.Don't remove the guards.

Good luck , play safe !

I'll probably burn a few more of those welding rods today just to experiment with em...See what kinda welds I can get....I'f I had known these rods worked so well , I'd have done the other stainless welding myself.
