    What is the best method to Mig weld 1/8" metal to 1/4" metal without blowing a hole in the 1/8"?
    Thanks

    My trick is to keep the wire spends twice the time arcing against the thicker sheet than the thinner sheet. That way you can get decent penetration in the thick stuff but not blow holes in the thinner stuff.

    I tend to establish a weld pool on the thicker sheet then dip into the thinner sheet and back in to the thicker sheet again.
