First off, I'm looking forward to learning how to TIG weld !!~80% of my welding will likely be on 0.040"-0.125" aluminum. The balance will be mostly stainless in the same thickness range.I have been advised to learn to TIG weld on steel though, so I will start there.Since the Thermal Arc TIG line of machines are not currently sold in Canada, it makes the most sense for me to buy any accessories I'll be needing now to ship up with my welder.1) It already has #3, #5 and #7 nozzles (the pink ceramic type) - any other sizes I should be looking at?2) I've heard you guys talk about "glass lenses" - are these see-through versions of the ceramic ones? and are they something that would benefit a beginner?3) what type of tungsten and range of thicknesses should I be getting?4) any other Thermal Arc accessories you'd reccomend? Any "must haves" ?Thanks in advance....
Reply:I think you're meaning a GAS lens.It's a type of collet body that has screens inside (see picture).With a gas lens you get better gas coverage, and a more coherent, less turbulent gas flow. In other words, you wont draw oxygen into your weld zone which can contaminate your weld.as far as tungsten electrodes, the most common sizes are 1/16" , 3/32" and 1/8"I would recommend a multi purpose type of tungsten either a lanthanated, ceriated or something like our ArcTime or Weldcraft's Rare Earth blend, that way you can use one tungsten for everything.GOOD LUCK! and have fun.-----------------------Carmen Electrodewww.CarmenElectrode.comand the boss blogs at www.JoeWelder.comall powered by www.Arc-Zone.com
Reply:So , you went with the TA eh ? Good choice You might want to consider picking up a few gas lenses to fit the collets and tungstensizes that you plan to use ( 1/16 and 3/32 are the most common ) .I find that they really do help when trying to get the tungsten into a tight place . Your LWSshould have these right on the shelf .Personally , I've had the best success with 1.5% lanthanated tungsten . It holds the pointed tip much better than ceriated or thoriated ( for me anyway ) and I would not goback . I now use lanthanted for both AC ( aluminum ) and DC- ( steel ) and they work great .
Reply:Are the gas lenses "generic" or interchangeable? My LWS is stricly Miller and Lincoln -- they haven't even heard of Thermal Arc The machine comes with some 3/32" 2% thoriated tungstens. Looks like I definitely need to pick up some 1/16" with the thin stuff I'm working on.My thinking is they should all be the same, except for thickness to remove one more "variable" from the learning curve.Last edited by turboguy; 08-05-2008 at 02:11 PM.
Reply:I'm suprised that your LWS has not heard of Thermal Arc, where are you located in Canada?

Reply:I have one. I posted a test drive with it. Nice machine! I have had it for a year. Used it yesterday. I keep it by my workbench for the small jobs that come in. Yesterday I got a Rototiller handle that was broken. I tigged it. Came out nice. 10 minutes. I did get a water cooled torch as soon as I realized how much I was using it.Here is a reviewhttp://weldingweb.com/vbb/showthread.php?t=13076David Last edited by David R; 08-05-2008 at 07:08 PM.Real world weldin.

Reply:Depending on the kind of plug... you should be able to hook up a Weldcraft TIG torch, no problem... or any other industry standard TIG torch your LWS (or online supplier :-) ) carries. I am not sure who makes the TIG torches for ThermalArcYour only consideration should be if you need a large DINSE plug or a small DINSE plug, or if your torch simply bolts onto the machine. Obviously one benefit of using, say a Weldcraft torch, would be that your LWS should either stock or have easy access to replacement parts (since as you say they carry Miller)-----------------------Carmen Electrodewww.CarmenElectrode.comand the boss blogs at www.JoeWelder.comall powered by www.Arc-Zone.com
Reply:Large dinse, Seperate gas line. The torch that comes with the machine is the best one I have used for air cooled.DavidReal world weldin. When I grow up I want to be a tig weldor.
Reply:Does anyone know if Weldcraft consumables fit the TIG torches that Thermal Arc TIG welders come with as standard?I'm thinking I should be buying some gas lenses in a few different sizes.

Reply:Thanks David & littlefuzz!What's the general consensus on the see-through cups? Will it help a beginner learn or weld better? It seems to me like it could be easier to weld in multiple positions with them.On the flipside, though, perhaps the arc will throw a lot more light back at you making it harder to "see".
Reply:Never used one or seen anyone else using them, seems kinda like a novelty item. It might help though DewayneDixieland WeldingMM350PLincoln 100Some torchesOther misc. tools |
