Thanks Bill. I think I may have seen one of those in an add, and thought it was a saw blade!
Thanks Blow by. We live in a breezy area. Fortunately it's calm in the a.m. and then windy in the afternoon. Although the wind chimes are ringing right now. I guess I'll have to weld in the garage. Any dangers to breathing Argon/co2? Would the shop doors being open be good enough or do I need to take additional precautions!
