| Hello Jim - If I simply reduce the O2 at the handle, I'll get a

|
| This group has had many good descriptions of how to get the proper
flame;
| you might want to look it up. Yes, it should be neutral.
|
| To give the short version, the inner flame should have a soft,
feathered
| edge, not a sharp, defined edge, and it should be a "quiet" flame.
|
| If it makes soot, there is not enough O. If it burns the metal,
(sparkles)
| there is too much O.
|
| You might need to move faster, take the flame further from the work,
get the
| filler metal in there faster, so it will get to the business of
melting, or
| even take the flame away for a second, every few seconds.

| Jim - I know how to make a neutral flame. I was just trying to figure
| how reducing O2 would help since if that's all I did, the flame would
| no longer be neutral. So I guess I need to follow your last para.

Just curious! Are you using the J-57 aircraft torch?
