  • Wire filler size?

    Hi, I am MIG welding 1/8" 3003 aluminum with 4043 filler wire. What size filler wire should I use?

    I have Millermatic 212 with spool mate 200 spool gun.

    I am building a motorcycle pull behind trailer with aluminum diamond plate and angle.

    Any help appreciated. Thanks

    .030 would be perfect but its hard to find in some places like my neighborhood so i always used .035. Then i talked my dealer into ordering some .030...Bob
