        i’m curious why my Miller CST 280 has weak arc start on tig with 1/16-inch tig electrode and 15 CFH argon, Can you give me a solution to this?

          Bump amps to 140 on your Miller CST 280, use 2% lanthanated tungsten, boosts arc start.

            Check gas flow on your Miller CST 280, use 20 CFH argon, improves arc start.
