Quick video showing walking the cup using a turntable.
This was a short production run of 50 carbon steel parts and the turntable really sped things up
WELD PROCESS = TIG, GTAW, GAS TUNGSTEN ARC WELDING
METAL TYPE = CARBON STEEL
THICKNESS = 1/4” WALL THICKNESS TUBE TO END FITTING
WELD TYPE = FILLET
JOINT TYPE = FITTING INSERTED INSIDE TUBE
POSITION = ROLLED ON TURNTABLE
AMPERAGE = 180-190 AMPS
TUNGSTEN = 2% LANTHANATED, 3/32"
FILLER WIRE = 3/32” E70S2
POLARITY = DCEN
GAS FLOW = 20 CFH argon
CUP SIZE = 8
ADDITIONAL SETTINGS =
PRE FLOW = .2 SEC
POST FLOW = 7 SEC
TIPS: KEEP A TIGHT ARC AND MAKE SURE THAT ELECTRODE EXTENSION IS CORRECT TO ALLOW FOR WALKING THE CUP OR FREEHAND TECHNIQUE
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
