I'll be the first to admit I am not a professional welder.
I do a few hours a week of mig w/steel with good results, in my past life I was involved in large vessel fabrication
I've had a Precision tig 225 for 18 years and up until 6 years ago was using it a few hours a week for aluminum and stainless (air cooled torch)
Any work I do is considered non critical or has any safety implications if failed.
Absence to tig was due to a variety of issues, but in the mean time I had picked up a Square wave tig 350 with water cooled system for a good price.
Within the last month have needed to weld some 304 SS similar to what I've welded in the past, decided to try the "new to me" machine with the water cooled torch
Along with my experience level I have 66 year old eyes. I seemed to have more of a problem seeing the puddle.
Not wanting to screw up the part, I decided to practice more.
I had bent up some aluminum trays 1/8" center sections with 1/2" end caps and decided instead of mechanically fastening I'd weld them to build up practice .
I see a huge difference with my seeing the puddle and surrounding area
using pure tungsten (green) with the aluminum
using 2% lanthanated tungsten (blue) with the SS
So should I see a difference in the puddle with the different metals, different tungsten and DC vs AC?
