Thanks for the tips, again ! My gas flow rate is 16 CFH and it seems good - no porosity on the weld. My tungsten is shaped at 30 degrees. I've heard that if you let your puddle go through to the other side of the surface, you can get porous weld, is it true?

Hmmm I tried bringing up the amps (from 60 to 70 amp) and traveling faster but I cannot avoid heat affecting. When I brush the weld it looks nice, but not sure whether it is good. Also, should weld penetrate and have those blobs on the other side or not?

Hi everyone, I recently purchased ESAB Caddy 2200i AC/DC welder and started practicing TIG welding only through online videos. I made my few welds now, but I am not sure whether is it ok - heat affected area seems to wide. I'm welding 50x50mm rectangular tubing, 1.8mm thick. Settings are following: ...
