    No black soot? Well, I guess there’s something else I’ve been doing wrong for over a decade.

    Yep. I bet you always wondered why your torch tip got hot. We learn something new every day.

    Not so sure the soot method works, maybe I'll pay attention and see it how proper it is. In fact, I can say without trying it that that is not a good rule. Because for some jobs, we need less heat and/or a carburizing flame.

    More importantly is with the acetylene only, the max pressure is when the flame begins to leave the tip.
    If you were a real tech, you'd solder a relay on that board and call it good to go.

    I do a triple evac with nitro to remove non condensables.

    I use 56% silver on everything except steel.

    Did you really need the " If you were a real tech " ??

    It works. It's what instructors teach in schools... It's also correlates directly to the psi the manufacture recommends on their tip size chart. So... Try it out

    I actually laughed out loud when I read that. I stopped using my rosebud because it would get the handle hot. And I’ve had a few jobs where I had to clean soot off of appliances near the furnace in a laundry room.

    Good god. I just fired up my rosebud on 10 psi and I don’t think I have the nuts to turn it high enough to get rid of the smoke. Jesus that’s a lot of flame.

    Sorry, doesn't make sense. Sometimes we need to use a low flame. So we use less acetylene. Pressure at the regulator is essentially meaningless so long as there is enough pressure to throttle back.

    I've only got three tips on my work rig. One is a rose bud. Everything else is done with pressure.

    In a perfect world, I guess you'd have a dozen tips. I've never lived in a perfect world.

    Acetylene at 5, oxy at 20.

    When you're done, open up the oxy to blow the flame out. Then close the acetylene.

    When you use the correct PSI to manufacturer recommends you don't get that flash back unless you bump your tip into something. Likely is never going to happen at recommended manufacturer pressure. I have a rosebud that's number three the flame shoots out with acetylene about 15 in. That's when all the is out then I turn on the oxygen till I get needle points.

    Yeah, you'd need a couple of dozen tips to follow that rule !!
