I just started off in the tig welding world, and need a used grinder to start off with. I don't want to jump into a new one yet due to the fact I may not be any good at tig. Thanks in advance for your time. Any info please contact me at [email protected]
Reply:get a bench grinder and have one dedicated grinder wheel for your tungstons so you dont contaimante the tungston,sears, home depot or northern catolog is a good place to start..brian
Reply:what about exact angles on the tips? do I need a dimond stone to grind the tough material? I did think of this but didn't think it would work.
Reply:FIRST, you're not making replacement heart valves, you're grinding a point on a tungsten, and that can be done with a cutting torch.Second, look at Fla Jim's device. It's far more accurate than you'll ever need and can be made for a few bucks.http://www.weldingweb.com/vbb/showthread...ngsten+grinderAppreciation Gains You Recognition-
Reply:you devolop a feel for it, and after a while you will wear a groove in the wheel it self.. always point the tungston up so you dont kill your self .i believe that you want your POINT twice the lenght of the diamiter of the tungston, so if you have a 1/16 tungston it would have a 1/8 in tip ..do a search for tungston sharpener on this site FLA JIM built a nice fixture for his bench grinder ''brian
Reply:Thanks for the tips (no pun intended) guys. like I said, I'm just starting out with Tig. So naturaly I am a little nervous about doing everything 100% by the books. But like said I'm not grinding heart valves.
Reply:There is some good basic info on grinding tungsten in the welding 101 section of the HoFart site.Let up a bit on the technicle part and relax a little, it will make the learning a lot easier and more fun.Appreciation Gains You Recognition-
Reply:majorboost, you in Plainfield NJ by any chance? I could not dedicate a wheel on my main bench grinder, so I got the small plasplug grinder and dedicated that to Tungstens. Works great. I recently saw Sears had a small grinder for like $20 that would also work well.If you were going to tig all day, every day, and on stuff like the space shuttle, maybe then a tungsten sharperner would make sense.BTW, I asked a similiar question when I first got my tig.
Reply:I am in Plainfield Il.I'm glad I'm not the only one that asked that question, it makes me feel a little better.I picked up a welder from Harbor Freight for $20, so here we go onto the learning process. I will have to read up a little more on (close to ) propor angles.Thanks for all the help
Reply:You picked up a tig machine for $20? Uh, like is that a typo?Asked about Plainfield cause Plainfield here in NJ is only a few mins from my shack. Tig takes some practice to learn, but hang in there. I'm struggling with it, but it's getting a little bit better.
Reply:Sorry grinder not welder(typing to fast for my own good). Everything I read says "if you can oxy weld you can tig weld" I have been oxy welding for years with great results so I thought I would try my hand at it. I just picked up a Thermal Arc 185 TSW. I used to mig weld mild steel roll cages and frames on performance cars and now want the high quality welds of Tig. I know it will take practice, but so did learnig to lay a strait weld upside down with the mig(with sparks going down your pants!).
Reply:That's the same tig machine I have and will eventually be doing some cages for offroading. My welds need to improve though first.
Reply:How do you like the machine? I was suprised with how small the thing was compared to the units they made only a couple years ago. It kind of freaked me out when I only saw one dial (the size of a quarter) and a bunch of push buttons! I'm grew up seeing huge machines with that looked like they came out of the movie "Frankenstein".I bought it for the amprage and duty cycle great ratings compared to other machines. Also the low amp draw out of the wall is nice. |
