Reply:A very simple, cheap and easy to use sharpener can be bought from..............I hate to say it...................Harbor Freight! http://www.harborfreight.com/catalog...lade+sharpenerRemove one guard that encloses the diamond wheel, chuck your tungsten in a drill and have at it. You can put any angle you want on very easily and can blunt the points if you want and use it to cut your tungsten to length.I've used one for about 2 years now and love it.

Reply:If you want something multipurpose. This is it. I have 2 of them. When the belt gets dull, flip it over and use it some more. I use this sander not only for sharpening my tungstens, I grind, radius, chamfer, and deburr parts with it also. The cost about $400 bucks. Bought mine about 20 years ago and other than having to reskin the backing plate they are holding up like a champ. I still believe they are made in USA.Weld like a "WELDOR", not a wel-"DERR" MillerDynasty700DX,Dynasty350DX4ea,Dynasty200DX,Li ncolnSW200-2ea.,MillerMatic350P,MillerMatic200w/spoolgun,MKCobraMig260,Lincoln SP-170T,PlasmaCam/Hypertherm1250,HFProTig2ea,MigMax1ea.

Reply:this is not a home item but i guess it could be; i keep it in my gang box on the truck. you can rest it on a flat surface upside down and lock the trigger to the on position and grind away. it's a little expensive but i see them on CL sometimes. beats the 7 in milwaukee grinder.[ame]http://www.amazon.com/dp/B0000223HB/ref=asc_df_B0000223HB1691782?smid=ATVPDKIKX0DER&ta g=pg-900-95-20&linkCode=asn&creative=395097&creativeASIN=B0000 223HB[/ame]

Reply:I am getting ready to test the 2% lanthanated.I have free samples coming from various vendors. They are pre-ground with different tapered angles. Some fine point and some are blunt. I requested the standard 20RA smooth ground finish over the 10RA mirror polish.Can't wait to test out the different included angle per taper to find out how they hold up to the different amperage.Edit: I just use a 6" sanding pad on a grinder, 80 grit on it at the moment. Also have a StiloTig enroute also.Last edited by skelley521; 09-06-2011 at 02:26 PM.Semper FiJesus may have been a Carpenter, but his dad was a Millwright" A grinder and a can of paint, will make a welder what he aint' "I've done so much, with so little, for so long, that now I can do anything with nothing!
Reply:I normally just use a belt sander as well. You can chuck your tungsten in a drill if desired. I have a little home-made gizmo that another welder turned me onto years ago, made out of a piece of small SS tubing and a bent piece of TIG wire...looks like a slide whistle....the tungsten rotates from the friction of the sander or grinder...
Reply:Hey Bob, I've been eyeballin' the blade sharpener out for some time now.How much of the wheel face has a diamond surface and how many time can you sharpen before replacing?Semper FiJesus may have been a Carpenter, but his dad was a Millwright" A grinder and a can of paint, will make a welder what he aint' "I've done so much, with so little, for so long, that now I can do anything with nothing!
Reply:Mine has a band of fine diamond coating that is 9/16" wide on a 4" diameter wheel. I bought an extra wheel with mine (about $10 IIRCC) but have not had to replace mine yet. I have turned it around and have started using the other side. If you touch up your tungsten before it gets all messed up it will last quite a long time. It does just as good as our $1000 dollar sharpener at the union hall and way better than using a sanding belt or a tiger paw on an angle grinder. Plus it's pretty darn quite. I've been using mine for a couple of years (not that much welding at home but I do sharpen my tungsten for work a lot of the time). Can't hardly go wrong for around $50-$60. Overall, I'm VERY happy with mine."The man of great wealth owes a peculiar obligation to the State, because he derives special advantages from the mere existence of government."

Reply:Regular 'ol bench grinder on a pedstal base with the guard removed is what I use..Stand behind it and use the top of the wheel..Cordless drill works great as a spinner.....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:Usually sharpen to about 2 or 2 1/2 times the diameter. My TIG welding is at about 70 to 100 amps.

Reply:I flatten the tip ever so slightly unless Im doing real thin stuff at low ampsI used to use an old wheel in my skate sharpener ( most important tool in the shop) I'd wait tillI had lots to sharpen then put on a worn wheel and chuck Em in my cordless. Now I have a triad. ( thanks josey) and use that. Down side is the the wheels are $60 each and don't last forever, but it does save humping the skate sharpener in the truck. LolG

Reply:How bout this idea guys? I have just been tinkering with the idea and i would like to have some support around the diamond wheel, but im not sure about the ring. Just a single piece of flatbar horizontally in front of the wheel, notched for different angles may be a better solution. Open to any and all criticism/suggestions.Cost, not including scrap steel for the box:12V generic AC fan blower: $17Diamond faced cutting wheel: $7 (harbor freight)I know 12V is not ideal, but I have a 20A bench power supply in the garage. The motor will be switched, so i suppose a small car battery would last for quite a while on a charge as well.Brad Attached Images----------MM180Lincoln PrecisionTig 225Hypertherm PM45Dyn 200dx
Reply:Wow this tungsten sharpening thing sounds strange to me. After grinding my tungston on almost anything that grinds for 40 years and shaping it for the job I haven't even thought about it for ages. I think right now I like using my belt grinder best. I just hold it in my hands and spin it with my fingers and it comes out fine. I will say you have better control if your grinding scratches run the length of the tungsten and not around it. And if you sharpen it very sharp you can always ball the tip at any time that you want to while welding. Mac

Reply:It will be interesting to see what these pre-ground tungsten's will do.Especially since they will be ground to specs w/ the flat tip dia. put on each for a specific amperage.They say with the mirror polish finished ones that you can't see a arc?Who watches the arc? We all know that tungsten is very forgiving, I just wanted to see what they do when done to a certain spec. and since they were free, what the hell Now I may call them back and get some of the mirror finish, I wanna see this Houdini arc....lolSemper FiJesus may have been a Carpenter, but his dad was a Millwright" A grinder and a can of paint, will make a welder what he aint' "I've done so much, with so little, for so long, that now I can do anything with nothing!
Reply:Here is some info they sent me via email:Electrode Tip/Flat: The shape of the tungsten electrode tip is an important process variable in precision arc welding. A good selection of tip/flat size will balance the need for several advantages. The bigger the flat, the more likely arc wander will occur and the more difficult it will be to arc start. However, increasing the flat to the maximum level that still allows arc start and eliminates arc wonder will improve the weld penetration and increase the electrode life. Some welders still grind electrodes to a sharp point, which makes arc starting easier. However, they risk decreased welding performance from melting at the tip and the possibility of the point falling off in the weld pool. In situations where very low amperage is used or short weld cycles are used (i.e., one second or less), a pointed electrode is desirable; however, for other situations it would be beneficial to prepare a flat at the end of the electrode. Guidelines for testing can be found in Table 6; also refer to the welding equipment manufacturers recommendations. During the welding operation, the accurately ground tip of a tungsten electrode is at a temperature in excess of 3000° C (5500° F). Incorrect or inconsistent diameter flat at the tip of the tungsten electrode can lead to the following problems: Pointed electrode tip drops into weld pool creating weld defect Reduction in electrode life Arc instability Change in arc voltage from one electrode to another due to inconsistent tip shapeIn AC welding, pure or zirconiated tungsten electrodes melt to form a hemispherical balled end. For DC welding, thoriated, ceriated, or lanthanated tungsten electrodes are usually used. For the latter, the end is typically ground to a specific included angle, often with a truncated end. Various electrode tip geometries affect the weld bead shape and size. In general, as the included angle increases, the weld penetration increases and the width of the weld bead decreases. Although small diameter electrodes may be used with a square end preparation for DCEN (Direct Current Electrode Negative) welding, conical tips provide improved welding performance.It's too early for me to read it, gotta sheet; shower & shave then I'm out the door,LatersSemper FiJesus may have been a Carpenter, but his dad was a Millwright" A grinder and a can of paint, will make a welder what he aint' "I've done so much, with so little, for so long, that now I can do anything with nothing!

Reply:By shovelon;I am surprised they don't give you a box of presharpened tungstens to hang off your belt. If you blow thru them, you can grind them on that nifty blade sharpener on your break. THEY DO GIVE YOU A BREAK I HOPE!
Reply:By Welding_Swede;So, it looks to me like you would be grinding the tungsten laterally with striations at a right angle to the electrode. |
