First pic is a practice box where the shielding didn’t hold up—still working on getting consistently clean results. Second pic? Just a fun practice die I liked.
These are the different setups I used:
Torch Cup: Jazzy 10
Tungsten: 2% Lanthanated & 2% Thoriated (both tested)
Stickout: 1/4” - 3/8”
Gas Flow: 25-35 CFH (tested different settings)
Torch Angle: 0-15°
Post-Flow: 7-10 sec
Material: 18ga mild steel
Amperage: 30-45 with and without 1-2hz pulse
Even with adjustments, still getting oxidation on mild steel. Does anybody have any words of recommendation or changes you'de recommend?
