I get what your saying and what I mean is this...get some plate..clean it...cut it up in to sections like in picture. ...then just practice laying flat beads until you can maintain consistency then start joining. ....we are all different in the way we pick things up and learn. ..this method is working for me and might help you....

You've got a good foundation to build on there but you need to sort a few things before they become bad habits that are hard to get out of.
The welds are unbroken runs of a fairly consistent profile but they have a weld face that is far too wide for the material thickness you are welding, you are also getting undercut on the vertical material face, so your next step needs to be reduce the weld size and get the heat input down considerably.
You now need to concentrate on travelling faster, do not weave the torch and add more filler.

Since I'm in front of the machine I thought I'd do in quick. Tbh I haven't got a 2.4mm gas lens body so done this at 100amps with a 1.6mm electrode, #7 gas lens, WP9 TorchTorch.
Mild steel, ground on linisher then wire wheel . pipe is 3mm ish and plate 4mm ish so well under on the amps really but this will suffice for example. In the photo is a 2.4mm electrode for reference.

That's how I feel. It's just getting my eye and hand into it. I need more practice and time. Fortunately I know enough theory to see what's bad. Nice to have someone back up my own thoughts.
Something I need to seriously crack is the muscle memory and being smooth not jerky its all time. And experience I think I've ran less than 40beads it will come Im pleased with my steady progression though. .
Cheers.

Thats not bad. But would suggest you saw test piece in half across the weld, and check the penetration. You need to aim for a narrower weld, with full penetration if at all possible. Best to spend time on simply running bead on plate, which will provide better understanding of controlling heat, that should make joints much easier to do.

40 beads would be far more benificial if they were performed trying to perfect the basics. As I've said a few times now you need to pefect technique in the easiest position (PA)(1G) on a plate before moving on. The pic above I did by showing a certain member some basic techniques of controlling hand movements and maintaining arc length, angle, filler while in the flat position. He's now IMO very competent with a Tig torch performing more complex joints as he's nailed the basics. (No prizes for guessing the member)

Running before you can walk, is something which I think means getting to a reasonably good standard takes much longer in any form of welding.

--EXAMPLE FOR OP-- Not perfect just an idea since i was sat in front of my machine with some scrap.Sorry my pics were not working yesterday
2.4mm tungsten for comparison. 3mm tube 4mm ish plate.
100 amps 1.6 electrode and filler
Needed more amps and 2.4 electrode but haven't got a collet for this Torch in 2.4 yet.
On the cleaning front that plate was seriously rusty and although ground and wire wheeled still pulled in contaminants, so you really need to go to town on your scrap you are using to practice with.

Bit of an improvement but the weld is still too concave, you can tell by the ripples you are not adding the wire regularly enough. I think you have hit the stage where any improvement is going to come slowly but stick with it, you will find it will fall into place all of a sudden.
To be honest I would forget about putting runs around pipe and concentrate on getting decent, consistent beads on plate first before moving on to actual joints

Practice, practice, practice, bead on plate, and always make sure material and rods are clean before starting. Its also not going to help technique much trying to weld joints using the wrong size tungsten. If you have AC/DC set you will find practice on thin aluminium sheet will be good for controlling heat, as well as torch angle and feeding rod properly.

Hi guys, think you've got the wrong end of the stick I put those photos up just as an idea on what sort of size the OP's beads should be on that pipe. I know its not great, but not much you can do when you've only got 1.6mm gas lens bodies and can't keep enough heat in the pool at 100A to flow enough filler.
Here is some of my work, at work, welded with Synchrowave 250dx

Thank you Richard I'm still learning if you see the thread I just posted I'm trying to get some proper tuition to move toward qualification and coding. Just a shame the place I've gone to is working out as it is, but its free seat time, I'm not paying for any materials or gas and I'm getting paid to be there.
