METAL TYPE = CARBON STEEL TO STAINLESS

THICKNESS = WALL THICKNESS 1/4” 

WELD TYPE = Fillet weld  SOCKET WELD SECOND PASS 

JOINT TYPE = SOCKET WELD

POSITION = TURNTABLE

AMPERAGE = 140 amps  

TUNGSTEN = 2% LANTHANATED, 3/32"

TIPS: KEEP A TIGHT ARC

 Aim for an arc length that is equal or less than the diameter of your tungsten electrode.Torch angle can be forgiving provided your arc length is tight.Keep the hot tip of the filler wire shielded by the argon envelope from the tig cup
