what is the best way to tig weld 1 mm 304 s/s and at what amp ?

---------------------------------------------------

A rule of thumb for welding sheet metal steels and stainless steels is one amp per one thousands of thickness.

1mm is about .040" = 40 thousandths

so 40 amps is in the ball park.

2% thoriated tungsten or 2% lanthanated tungsten in the .063" or 1.5 mm diameter will be the best choices for electrodes.

sharpen it like a needle with a fine grinding stone or sanding disc

use a #7 tig cup with a gas lens

308 L ss filler metal 1mm or 1.5 mm
