Problems with tiging tube
Big tube 83mm x 5mm small 50mm x 1.5mm
104\ 112 Amps pulse at 20hz 2.4 tungsten No7 cup 10 \ 12Lpm 1.6 filer in workshop with low volume\speed air extraction
Am getting blow holes as pic's
Mill scale ground off on both pieces internal of 50mm cleaned.
Also the tungsten burns this is not just on this job
There are a couple of blows on the cap (was hand cut & not round) of the 83mm but a lot worse on the 83 to 50mm
I know it is not tidy but my joints seizing up don't help.
