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!:eek:

you should be fine in a shop with the doors open, just dont huff it out of the bottle! im not sure about co2, but argon displaces oxygen, and it can build up in your lungs. if you get the feeling like your lungs are getting kinda heavy, then stand up and bend over to get the excess argon out, kinda breath out real hard to push it out of your lungs. This is what they told us in welding school. i wear a special welding resperator when i am welding, it helps with the burning metal fumes too!

Thanks Hotroddaddy! One great thing about this place is all the help for people like me, new to welding, etc.
It's funny, because a few months ago I was fretting about how to get the truck to an exhaust place, running it with straight headers, and not getting a noise ticket! Now I can do it myself, and with the savings, put it right back into the engine! Some bodytold me, once you get one you'll find all sorts of things to use it on. Now I see why!:D

You can use a 2 % oxygen 98 % argon for a spray arc. Works great on steel as the spatter is almost nonexistant. It's a very quiet arc when done correctly. We use it at work all the time on up to 1 inch thick. Also lots of heavy TIG wielding 200-300 amps.
