WELD PROCESS = TIG, GTAW, GAS TUNGSTEN ARC WELDING,
METAL TYPE = 304 STAINLESS STEEL
THICKNESS = 2 INCH
WELD TYPE = BUILD UP PASSES
JOINT TYPE = BUILD UP PASSES
POSITION = FLAT
AMPERAGE = 120-150 AMPS CONTROLLED WITH FOOT PEDAL
TUNGSTEN = 2% LANTHANATED, 3/32"
FILLER WIRE = 3/32” ER308L
POLARITY = DCEN
GAS FLOW = 20 CFH argon
CUP SIZE = 8
ADDITIONAL SETTINGS =
PRE FLOW = .2 SEC
POST FLOW = 11 SEC
TIPS: GET THE PUDDLE MOVING WITHIN 3 SECONDS.
LET COOL TO BELOW 250F BETWEEN PASSES TO MAINTAIN STAINLESS PROPERTIES
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.
Whether you are a student working on passing a welding test, hobbyist, or a working welder who wants to sharpen up, I want to encourage you to take the free 7 day test drive and get access to all the courses and over 700 videos.
Get in there and lets all get better together.
Its easy to sign up…and even easier to cancel with no hoops to jump thru.
Invest in yourself,
See you in there.
