Well I just spent some time playing with my 250 ex.
and realize I have a lot to learn.
I see now that I did not have to worry about becoming good at tungsten sharpening. as I will get all the practice I need. I can finally run the torch at least four to six inches (the length of my scrap) and not stick it so that's good, and I am starting to see the puddle better. I started to add filler and this process is what will help me get good at sharpening. I also like the neon green flare that alerts you to fire up the grinder.
I hope to do some more practice on both beads and sharpening tomorrow and will take and post some pictures then
