How do I get proper penetration on thinwall 0.7-1.6mm T-joints or coped tube?
I keep getting burn through away from the corner itself and barely any penetration in the root itself. If I try to increase the heat, I get burn through where the electrode is closest to each of the 2 parts, about 1-2mm from the actual joint, as if you drew a perpendicular line from the electrode to each piece of metal. I know it's because that's the shortest distance from the electrode to the work, but I don't know what to do about it.
If youre talking about stick then it sounds like too much arc length. hold the electrode closer to the metal. The further the rod is away from what youre welding the more the arc spreads out, if its nice and close it focuses the arc into the root. for t-joints I usually just drag the electrode along the metal.
my point about arc length applies even more to TIG. hold the tungsten close to the weld. your arc length can never be too short, the closer the more concentrated that arc is straight into the root. a longer arc length forces your welding plant to increase the voltage and it spreads the arc over a wider radius so you wont penetrate into the centre.
another reason could be youre using too big of a filler rod. If youre not pentrating into the root it means youre probably laying the filler on the metal and welding over it, try dipping the filler into the puddle. dip the filler, move torch forward and watch the puddle go into the root, then dip agian and repeat.

Worth as a first welder?
I got certified in mig, tig, and arc welding about a decade ago, but just bought a house and installed a 60 amp breaker so I can actually get my own welder finally.
I've seen worse
Eh, I've done worse. That's what an angle grinder + gap filler are for before hiding my shame with a coat of paint
Black person your weld isn't that impressive to justify posting it second time
Yes.
Looks like the shit I took this morning.
If you enjoy looking at shit welding, check out the Facebook group "I see you don't know shit about welding".
I see you're a man of class and sophistication like me...
still sucks as bad as the last time you posted it
Yeah that weld is ass, but not as much ass as the inside of my cannon safe.

Tig it, or put the majority of the heat into the thicker material (IE not the corner)
It's TIG, I'm just shit at welding

It should hold up fine.
excellent work

Picked it up for $300
good buy, anon. INE wire on Amazon is excellent and cheap. that machine will run .030 wire awesome

keeping the pool too hot and for too long, its not TERRIBLE but it aint good
