Tungsten Recommendation

by George

The machine is a Lincoln Precision Tig 225,primary use is for 4130 tubing. What tungsten do you recommend, Ceriated or Lanthanated? 1.5% or 2%? Thanks George


I like to use 2% lanthanated for everything.

but for 4130 only, you wont see much difference on ceriated, thoriated, lanthanated, etc.
