Ive been browsing here for a bit and decided to register. I just got around to using the spool gun that came with my Esab MM 250 and need to weld some cracks on an aluminum boat. I was wondering if anyone here has the same spool gun and welder and could give me some initial settings for spraying .030 aluminum wire. The tips I have are 045 and they came with the welder.I believe the boat im working on is around 14 gauge but Im not sure the type of aluminum yet. Thanks for any help.
