Well, now I convinced myself that I can do it next time I'll need to do some welding work on my car parts. All I have learnt will have to wait until then, and also then I will be thinking about getting my own equipment. This is more difficult than the welding itself. the choice is basically between a good used one or a new chinese but decent one (considering the amount of welding I can forsee, the cheap-product-factor should not be an issue). I like the machine that I have rented (Rehm Tiger DC) for what it can do weld-wise, but I do not like its one-knob control system. In any case even a used one is in the range of 1000 Euros, this is twice as much as I would consider spending.
Another things is of course learning the AC welding on aluminium, but this somehow does not yet excite me so much, I still have so much to learn about DC welding.

Have a search for MIGTIG Italia they have ACDC sets going on ebay for little money. I've a Plasma by them, works a treat.
No wonder really, they look remarkably like R-techs

So my final weld turned out to be two. I made one with 45/20 amp split at 100Hz, it came out nice on the outside (first pic) on one half (the other half I somehow could not tune myself in), then I cut the pipe to see the inside (second pic) - not so good, penetration lacking in some places and I also forgot to turn on the back purge for one of the sections. But since I just had the pipe cut, I welded it again now at 50/20. This came out way better (third pic, the weld to the right), although it seems a bit more erratic on the pic, in reality it is much more uniform than the first one. Also I can see from the distance that the inside came out much better, but I am too lazy to cut the pipe again to check, perhaps on Friday.
So the inside of my last weld, better than the previous one, but still missing it in places. I guess I could have welded it with more juice still.
Anyhow, I got rid of the welder, one thing that I did not try, but wanted and forgot, is to see how the lift-arc starting works. Just to get an overview.

So I have one post-fact (as in I do not have access to the welder anymore) question. A while back I read here on this forum somwhere that the visual of the weld puddle gives a hint of whether the weld is penetrating through. I cannot find the post on that. Any insights on this? Instruction picture or video?
