Thread: MIG welding - gas or flux core?

Tweet

My local welding shop rents tanks for 6 bucks a month+ gas refills. Its a good way to go if you do not have the upfront cash to buy a bottle and gas. Once i had the cash i bought the tanks, i think it was 140 a tank filled, not a bad price! but you are in the land of spending, so your price might be higher.

You know that might be just the ticket for now. Rent gas for the body jobs, save money for engine, and get a tank down the line when it is more affordable!

.....this is the sheet metal gauge that you were referring to. Most welding supply stores have them..... Bill

Gas is the way to go by far,but also remember that if you are welding outside a lot gas won't cut in any type of breeze.

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!

.....LOL, a saw blade!!! good one....

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!
