I need some help with an issue

PR, as you know I earn a living with a welding hood and I would not spool gun that. I would heli arc it. Remember regardless of your skills you are going to grind it down and polish it a bit so no worries on your skill set! Grinders were invented to hide sin. Great practice on a part you literally can’t tear up. Use 1/16 -4043 alum rod and pre heat it a bit and you will be fine.
