OA welding help!!

Didn't know about them. It has been most of ten years since I last used a Henrob torch, and this must have happened since then. Wonderful! Forget about drilling the small one, then.

Seems the #.5 is the number 1 option these days. You weren't alone.
I just started with the Henrob though after using a Victor 315 for 10 yrs. I guess that is why the Henrob doesn't feel heavy to me like others state :)

OK, got my Meco Midget from the tinman a coule of days ago and have been trying it out. I've only welded with the one (mystery) torch, so I only have it to compare it to. Firt, it's light. Really light and really small. The hose is very light too. Doesn't quite obviate the need for me to wrap it over my shoulder and around my arm, but it makes the burden almost nonexistant. Because it's so small your hand is quite close to the work. Even using a number two could get a little uncomfortable with no glove on, especially as the heat was coming up a tube pointed at my hand at one point! Anyhow, that;'s the only disadvantage I've seen so far. The precision of the valves is at least ten times finer than my previous torch. You have to crank them like mad to get the flame set just right and then it stays there. IOW flame control is really precise and very easy. I've also noticed that the required pressures at the regulator are about half of what i needed for my other torch, particularly for the acet. I'm finding control of the puddle quite a bit easier with this. In spite of it's size the flame is plenty to get a puddle going. I'm still adjusting to it, so my welds aren't much better yet, but they are beter already after only about two hours of practice with thing. I'd say when I've gotten used to the contraption they'll come on even more quickly. I'll let oyu know in a week or so!
Many thanks again to everyone who's helped!

Yeah, those Meco Midgets are great. Be sure to get the lightweight hoses, extra tips, and "fish mouth" wrench too, if you can afford them.

OK, got an experienced welder to look over my shoulder, fianlly, and tell me what I was doing wrong (local shop teacher who is also building an airplane) You're absolutely right. Not feeding the rod in aggresively enough. Couldn't really back off onthe heat coming formthe torch as I had it set to the minimum to get the puddle started in the "V" of the tube joint, but once I was out of it the heat was a bit too much and unless I wanted to stop and readjust the flame, the est way to control it was to add more rod, something I was shy on doing. So instead of dabbing it in the puddle every now and again, I'm very nearly making a constant feed of rod to keep the bead proud of the joint. My welds aren't perfect, but they're a hell of a lot better and the undercutting problem is almost completely gone.
And the Meco torch is just brilliant..
