Cup size

admin

Hello, greatly appreciate tips ....What cup size is recommended for tig welding 20 gauge 316L or 308L using .040 tungsten? What about a gas lens? Thank you!
Reply:Depends on allot of things,  joint type, travel speed, amperage... What colors are allowable? Going to have a heat sink?  I would use a #6 cup,  prefer a gas lens but it may not be required.Airco Ac/Dc 300 HeliwelderMillerMatic 200 (stolen)Miller Maxstar 150STLMiller AEAD200LE (welding and generating power) Hobart MIG

Reply:Thanks Dave. At least I'm not disappointed that someone didn't post up picts with a title like that. .No government ever voluntarily reduces itself in size.

Reply:You sexist pig.It doesn't matter what cup size she has. If she can lay a bead, she can lay a bead. TIG is not gender specific.

Reply:OK back to tig welding ............I like a larger cup for AC  with higher amps than 150  1/8 in. tungsten....Unless there is a reason to extend the tungsten I can't see a reason for Gas Lens.....Since I run a lot of Helium with my parts I have found running a higher flow rate is necessary to get good coverage......Most of my aluminum stuff is done with a 6 std cup....2% Lanthanated Last edited by B_C; 01-01-2015 at 10:13 PM.  Miller Dynasty 350Twenty Six HammersThree Crow BarsBig Rock
