oxy/acet or turbo

You might need to cut some steel someday.

Yeah I am kind of leaning that way too. Don't have a lot of money to throw around righ now. I always seem to break something on my tractor and have to cut a chunk of steel to fix it. I have been at work all weekend, 12hr cateye and didn't get to the computer. I am in the middle of putting in a straight A/C 3ton colman for a fellow that he bought used. Got the coil in Friday. You have to know this guy, he wants to spend little to no money on it. Someone did a really good job on his duct work. After setting the coil I wanted to have a friend of mine make another transition for him but he didn't want to spend the money so he helped me cut down the existing duct.
I got it in there and it looks fine just does not have all the nice connections that it originally did.
While at R.E. Micheals I was looking at the torch sets and the salesman asked me which one I wanted. I told him I was right now setting a 3ton R-22 unit and he told me to just use 6% soft solder and Mapp gas. I didnn't think this was a good idea but he said it will work. I have always seen people use the 15% sil-foss.
I think I will borrow a air/acet torch from the instructor that gave me tha EPA exam.

Do not braze with mapp gas. Whether using 6% or 15%, use either turbo-torch air-acetylene system or oxy-actylene. As mentioned previously on this thread, if you can only afford one, get the oxy-acetylene. Turbos are nice and light, but you cannot get by with only that...

oxy/acetylene with a rose bud tip.In and out fast.

Do you wear a mask when welding?

Do you wear a mask when welding?

When welding, yes.

When brazing or soldering, no need, really.

Mask,mask I don't need no stinking mask.

I use the Turbo for soft silver (mostly water lines). For gas lines, most all local codes require hard silver brazing. For this and anything bigger than 1/2 inch, an ocy-acetylene is easier and faster. Try a turbo torch on a cold, breezy morning on a rooftop working on a 1 1/8 inch line! Good luck! I pay the extra money and use 15% silver rods. I use 45% silver on steel-to-copper with flux. Of course, this depends if you know HOW to braise. Just look at some units that have been installed sometime. Lots of piss-poor braising that lead to lots of refrigerant leaks.

why would someone buy a torch, employer should provide this

[Pascone10]

i bought both my oxy/acet and turbo torch. what size tanks do you use for the oxy/acty

[Tool-Slinger]

I use the smaller tank for the turbo, same size as the oxy kit. Johnstone sells an adapter.
