WELD PROCESS = TIG, GTAW, GAS TUNGSTEN ARC WELDING,  

METAL TYPE = carbon steel PIPE

THICKNESS = 2 inch schedule 80 pipe wall thickness .220"

WELD TYPE = groove   

JOINT TYPE = BUTT WELD

POSITION = 6G pipe OPEN ROOT WITH 1/8” GAP AND ZERO LAND

AMPERAGE = 80-90

TUNGSTEN = 2% LANTHANATED, 3/32"

FILLER WIRE = 3/32” ER70S2

POLARITY = DCEN

GAS FLOW = 20 CFH argon

CUP SIZE =  8

PRE FLOW =  MANUAL

POST FLOW =  10

ADDITIONAL SETTINGS =   

TIPS: EXTEND ELECTRODE ENOUGH TO GET A DECENT ANGLE SO THAT WALKING THE CUP OR FREEHAND WELDING BOTH WORK WELL

 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

Snip oxidized tip of filler metal before a restart
