To Much Tongue

Getting into the sharp angle of the tongue with the standard mig gun nozzle didn't work all that well, so after some searching on the internet I determined that I would buy a couple spare nozzles and take the old one and grind it so that it could fit closer to the seam that I wanted to weld.  This will be a lesson, don't design parts that have very deep corners if you can avoid them.


Here is the modified nozzle.  Initially I started with both ends sharp but found that it fit too well and I couldn't see around it to the weld puddle, so I shortened one leg so that it obstructed the view less.


This could have been completely avoided by making the straight portion of the tongue flush or nearly so with the A-Frame, it would have been easier to weld, and I would have only had to make one large gusset instead of the two small ones.  This is what I should have done, but not being an experianced fabricator, didn't.
