WELD PROCESS = TIG, GTAW, GAS TUNGSTEN ARC WELDING
METAL TYPE = CARBON STEEL
THICKNESS = 1/4”
WELD TYPE = Fillet weld
JOINT TYPE = TEE JOINT
POSITION = 2F HORIZONTAL
AMPERAGE = MACHINE SET TO 177 AMPS CONTROLLED WITH PEDAL BUT MAXED OUT SOMETIMES
TUNGSTEN = 2% LANTHANATED, 3/32"
FILLER WIRE = 1/8” ER309
POLARITY = DCEN
GAS FLOW = 20 CFH argon
CUP SIZE = 8
ADDITIONAL SETTINGS =
PRE FLOW = .5 SEC
POST FLOW = 7 SEC
TIPS: KEEP A TIGHT ARC and adjust electrode extension to same as cup diameter so in this case that would be 1/2"
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
