I did some checking at the local welding shop and learned that my 40 cubic ft actelyne tanks can not be drawn down at a rate high enough to support a tip for 1/4" steel, without exceeding the 1/7 draw down rule. So now what? I have the occasional need to weld 1/4" stock and would still like to use this rig for that. Would using MAPP gas instead of actelyne gas work OK? I don't think the 1/7 rule applies to MAPP, but what are the pro and cons of using MAPP (or for that matter any other fuel gas).

I believe that the standard solution is to either go to a bigger tank or to manifold two tanks together.

Pete,
Some of the more common fuel gases besides C2H2 are Hydrogen, LP, natural gas and MAPP to name a few. Hydrogen does not produce as high a temp as C2H2. It is very clean though and is recommended for welding aluminum and magnesium. It's used underwater because it can be used at higher pressure.

Natural gas and LP probably need no explanation.

MAPP (methylacetylene propadiene) has the same safety and ease of handling as LP gas. Heating values approach C2H2. You can use your C2H2 regulator with it. The threads are the same also. You should use MAPP tips though. They are available for all common torch outfits.

Since MAPP gas is not derived from calcium carbide, there is no acetone needed to stabilize at pressure. MAPP pressures can be as high as 90 PSIG. MAPP cylinders also contain more cubic feet of gas than C2H2 cylinders of equal size. Mapp will cut faster than C2H2 but the flame cannot be adjusted narrow enough for fine, pinpoint welding as with C2H2. Hope that sheds some light on it for you.
Steve
