it think i got it going now frosty- new video

[armymedic.2]

I swapped the .025 mig tip for a .035 like you said, instantly a ton more blue flame, but it seemed to still not be getting enough air. 

I put four more aspiration holes in a ring below the ones that i had already, in effect setting the tip back amongst the holes (like you said to), also giving it more places to suck air in from,

 

it now runs on a wide range of pressures, has some dragons breath, and is hotter than i have ever had it before.   it was a pleasure to hit the steel.   i was able to achieve a lighter orange than ever before on bigger stock, and hit a pure yellow on smaller and tapered stock, but i never got to a white heat.  i deliberately did try to burn some metal.   no dice.   i think painiting some plastix might help.  

 

 

and of course,

    is it running optimal now or is it still too much blue or something else im missing?

 

thankyou for all of your help, it is making such a difference!

 

best,
