TIG Cup Size

admin

My TIG cups are numbered. I.E. 4, 5, 6 etc.  My TIG calculator uses a fractional reference.  I.E. 3/8, 1/2 etc.  Do the numbered cups have a correlation?For example:  Number '4' cup = 1/4" cup. Ironheart...Beat it to fit, paint it to match
Reply:beats me...i just use what i feel is needed for the job......zap!I am not completely insane..Some parts are missing Professional Driver on a closed course....Do not attempt.Just because I'm a  dumbass don't mean that you can be too.So DON'T try any of this **** l do at home.

Reply:And the zapster posts another ego fueled answer....How about coming down off of your lofty perch zap and answering the mans question....or maybe you don't know the answer..??Some of us like to know the "why" of things, i.e. cup designations, angle of a grind on a tungsten rod, etc.
Reply:Originally Posted by IronheartDo you think the cup number goes over 16?For example:  Number 4 = (4/16) = 1/4                   Number 8 = (8/16) = (2/4) = 1/2Sounds good to me.  Thanks for your help.

Reply:Sixteenths.....The number represents the size of the cup in sixteenths of an inch.....Like Ironheart said.Patrick

Reply:LOL...well zap you've already "proved" to me all I need to or care to know about you.....Oh and it's called intellectual curiosity...the asking of why certain things are used or done a particular way....us beginners tend to ask lots of questions and we ask them of people who are "supposed" to know the why, the what, and the how-to.  A simple explaination would have sufficed.Have a nice day....
Reply:GAS NOZZLES (Cups)They are used to direct the shielding gas over the tungsten electrode and to cover the weld area with shielding gas.  Nozzles are made from different materials.  The most commonly are:•Ceramics•Metal-Jacked Ceramics•Metal•Fused-QuartzNozzles are identified by the size of the orifice (opening) by given number measured in 1/16” (1.6 mm) increments and by the length of the nozzle.  Example:  A number 6 nozzle thus has a diameter of 3/8” (6 x 1/16 = 6/16” = 3/8” or 6 x 1.6 = 9.6mm).  Nozzle’s opening is selected according to:•Amount of gas flow•Weld joint type•Accessibility of the weld area•Welding position•Tungsten electrode diameterIn general, a nozzle opening is about four times the electrode diameter.
Reply:i have a few sizes and was going to offer to mesher them but it seems the anwser is already coverd, thanks good info to know when ordering. especily for the new to TIG guys.although its almost a lost art to use the standerd cup's any more as the gas lenses are comming way down in $$ and do a much better job, as well as saving gas. although they can also be used with standerd cup types if you use that type. summer is here, plant a tree for mother earth. if you dont have time or space, sponcer some one else to plant one for you.feel free to shoot me a PM or e-mail me at [email][email protected] i got lots of time.
Reply:On the subject of nozzles, wanted to point out that there are two common types, the Alumina (pink) and Lava (cream).  I was taught that the Lava type is recommended for AC TIG aluminum, not sure, but I think they stand up better to the high heat, maybe don't break as easily as the Alumina.  But I don't think the Lava is made to fit a gas lens.Another nozzle type is the Pyrex clear glass, like those from http://www.ckworldwide.com
Reply:i have both the clear and the pink setup for the gas lense, not enough tine on the tig to make a preferance but its nice to be able to see threw the clear when lerning. i read an artical about the different types of cups just a lil bit ago i'll see if i can did it up and post it for you all. summer is here, plant a tree for mother earth. if you dont have time or space, sponcer some one else to plant one for you.feel free to shoot me a PM or e-mail me at [email][email protected] i got lots of time.

Reply:some times its best to just let it go and if possible, give better advice.personaly i have never understood why on a forem for asking questions people get upset if you ask a question that has already been asked true there is a serch function but some that are not so good at computers or wording the serch corectly have verry little luck with them, i happen to be one of thouse that are realy bad at serches, weather it be here on a forem or on ask jeevs or whatever the internet serches are. wile most will try to give good and helpfull advice some will always speuw out "thats been asked befor why dont you do a serch" odds are prety good he wasent here when it was coverd befor and may not be too good at serches, could have even tryed the serch already??or maybee he is looking for a diferent opinion than the ones given befor as perhaps some one new will have some thing new to ad to the answer?so when you get a not so polite responce its always best to just let it go and move on as if it were never there, makes them look a lil silly when you dont resond to there lack of usefull input.     sorry just wanted to see what the alien looked like. summer is here, plant a tree for mother earth. if you dont have time or space, sponcer some one else to plant one for you.feel free to shoot me a PM or e-mail me at [email][email protected] i got lots of time.
Reply:Hello,WOW...... all this high anxiety everybody take a chill pill!!! If I understand the query it was regarding the relationship of the cup number designation relative to fractions or what ever the numbers on the cup relate to. As you have already read they relate to the ID of the cup in 1/16" increments. IE : 4=1/4",6=3/8", 8=1/2" etc. up to 16 that =1". Numbers 4-16 are the industry standard designation for the standard ID nozzles. Sizes smaller than 4 are used primarily for Micro Welding with .020 and .040 tungstens. Anything larger than 16 are typically identified by their actual ID size such as Monster nozzles that for example measure 1.250"ID X 1.00" long. In my opinion contrary to what we read, I prefer Alumina (pink) for almost all the welding I do regardless of the statements that would have us believe that Lava (tan) is better suited for working in confined and enclosed areas. I weld  automotive heads and blocks made of aluminum and cast iron daily and use Alumina nozzles, normally 5&6 sizes by anything from 7/8ths long to #795XXXL  which is 5/16"X3.500 long and all lengths in between and I weld inside cylinders and ports with the torch inside the cavity's with no problems such as cracking or melting. I have nozzles in both Alumina and Lava  and have found over the past twenty five years that the Lava nozzles will melt at the tip when used inside a very restricted port or hole at high amperage. I would be happy to send you a free sample of any nozzle you may want to try in both materials and let you decide which suits you best. Just send me a message. And don't be put off by Zaps answer, he is a very qualified respondent and perhaps he, like I at times, forget what we didn't know when we were still trying to weld things together with a battery charger and a paper clip. And for what it's worth his answer was truthful and correct it just didn't answer your question. Many times more experienced welders do just what he suggested, choose the one that works best for you. Many times the textbook answer just doesn't work as well in the world we weld in or with the girls we dance with. Hope this helps.Good Luck,ric  There is still the matter of what the P/N on the box of nozzles means  such as A796F70 or 796F73 or 13N14 or 13N19 or 53N58 or 53N61 understanding this number designation will allow you to know WHATS IN THE BOX.Maybe some of the ill tempered respondents just saw the ELECTION RESULTS!!!  Hello Zap

Reply:Holy sh**  Do we need to organize like a big group hug or something.  OK  at exactly 7:00 pm Central Time everyone reach around and hug their monitor so that we can all feel better and get back to business.IT Welder sometimes it's better to be the better man and let some things roll off your back.  Offer what help you can and let everyone digest the answers as they see fit.  I am a hobby welder that is starting to make money with my equipment but I am a CTO by day so I can relate to needing to know the "why" because it is necessary in my position.Zap is just Zap, sometimes you get pearls that you can use and other times it might be a grain of sand.....but either way it's Zap and he does help out a lot.  I look forward to seeing his projects that he posts because the pictures of what he is doing is better than any rant on this board.  You need to remember it takes a bit of effort to constantly stop, photo, and upload it for someone elses benefit later in the day.  I appreciate that very much.  I don't always appreciate his short 1 liners but that's why they invented the scroll mouse.
