I wanted to share a very advanced technique I have been working on since I started tig welding.
Not everyone can do it, takes alot of focus to perfect.
I was working on a $1500 Gearbox and snapped a hex bit off flush in a fastener. Rather than scrap it.
Light up on it, let it heat cycle. About heat cycle number 3 let it start to puddle nice tight arc. Here's where things get real. Slam the pedal to the floor and simultaneously bury your tungsten in the bit. Immediately let off. Even if this doesn't work trust me you will find satisfaction. It just feels so right.
Loosen the collet body leaving the tungsten behind. Let things cool off and pull her out.
It's taken years of practice, lots of tungsten, trust me you too can do it!
I like to call this hail mary, sink or swim.

I have experienced worm tracks in the past using this process. I need to try these settings as I was a bit hotter 27.5 /285. Lincoln ultra core .045. I have been told worm tracks is known challenge with Lincoln wire. No idea this is my first roll of DS.
As a general rule how do you go about diagnosing this problem? I increased gas, decreased gas. I increased and decreased stick out which helped only mildly.
