I contacted Lincoln Electric regarding the AC Output Frequency of the Precision TIG 225, it is 60 Hz.

I contacted Lincoln Electric and asked them to provide a description of the AC Balance and Pulse Frequency demarcations as shown on the front panel of this welder (see front panel closeup posted previously), including the fine resolution of these controls. I also asked them to provide the AC Output ...

To whomever is interested: Lincoln Precision TIG 225, AC Balance, balanced EP vs EN Vernier Control, in the time domain. Rotary Scale to Linear Scale in percent, for the EP Time On to the EN Time On, of the square wave. 1 | 2 | 3 | 4 | 5 | 6 20 30 40 50 60 80 70 60 50 40 30 25 EP, Electrode Positive...

Steve, Thanks for the positive feedback. Sorry for not posting a follow up table for steel and aluminum, had a stroke in 2015. Recently I returned to the forum with a few more bits of information for the PT225. Update, November 2019 Regarding the Lincoln Precision TIG 225 (PT225) Duty Cycle, one sho...

DeepSouthWelder & MosquitoMoto: DeepSouthWelder, I have used quite a few different types of saws, for your application (and I don't have much to go by) I believe the portaband type saw might be the best choice. Pick up a Milwaukee 6230N Variable Speed (5 specific speeds: 1 - 5; 1=84, 2=168, 3=25...

On an Ethanol plant, I was doing a lot of structural with 7018, and building conveyor transitions with 308 MIG. We naturally had to cover all the wire trays with fire blanket to protect them, and were careful and thorough about it. A young "first field job" electrical engineer assaulted m...

I don't know about that Otto Nobedder guy, seems a little shady. LOL Wob :lol: PS The first time I watched a man forge tools and other items was in Williamsburg,VA. The second time I watched a man forge tools was at the San Francisco Exploratorium, I was fascinated, what a fulfilling job to perform....

Thanks Len & Steve,
Blue Gold goes on my list of things to get, as well as a black-light.
Since this cleaner is for promoting good TIG welds, does that mean I have TIG C-OCD?

Hello folks, My skills with TIG welding aluminum have been improving, slowly but improving. I've used up a lot of filler rod and all the scrap 1/16" to 3/16" pieces of aluminum I could get. I am having a terrible time welding the inside corner of a 90 degree joint. Outside joints are goin...

Len,
You mentioned Magnesium, how about Aluminum?
Is the cleaning sequence: clean with Blue Gold; then Stainless Steel Wire Brush?

Bruce

HI NYWELDERJim, When I purchased my first TIG welder, I also chose to use AL (6061-T6, 1/2"x30"x72") as my working surface. This very flat plate sits on a 12 ga. all steel work bench with adjustable height legs. For steel, I use a moveable work table with steel casters, a 3/4"x36...

Len, That's allot of great information Len, thank you for describing the torches and models, this really helps me make a decision on the entire water system. I will not be welding anywhere near 300 Amps with my current machine, but having the capability available for a future TIG welder purchase wit...

Thanks Len, I do remember seeing a picture or add for a Binzel and it, except for color, looked identical to a Miller Coolmate 3. What torch do you connect to it? What TIG welder is used in your water cooled system? Is the spinning paddle wheel helpful for viewing flow? Do you have to get very close...

To anyone with experience on the Miller Coolmate 3,

I am preparing to purchase a Miller Coolmate 3 to support a cooling system for my Lincoln PT-225.
Are there any users with advise on this TIG torch cooler?

Thanks in advance for your reply,
WOB

To all, I checked out the Lagesse Products website, the square Jody is offering is the standard graduation model (LAS-12S), there is also a machinist blade that is ground, and has increments down to 1/64. The lines and numbers of the machinist blade are colored in black. In addition to the finer gra...

xwrench, Very nice implementation, it looks like they are both well made and ready for use. I to have a 2x72 belt grinder (not sander). As you say they are beasts, able to decimate a very hard file in minutes. I wired mine for 230. I did not have the time to build it as I was still working at that t...

Bugel, Very nice cart, welding table, and numerous other stands and equipment support racks. I can see you strive to pay attention to the details. Do you draw/document your designs as well? Do you have access to some CAD programs to make drawings? I can see a modification to your cart will be requir...

Great job Dave, I enjoyed the pictures and shots of your welds. Did you build a fixture to assemble the main panels ? Regards, Wobulate (Bruce) P.S.: Looking at your drawings, thats how I start my projects. When I was working I had to use Microsoft Visio Professional, so now that is what I use to fi...

I changed the way that I prepare tungsten, lately I have been using my Belt Grinder with a Norton Zirconia belt. This method worked, but I used one $9 belt in one 4 hour welding session. Tungsten is hard!!!!!! I decided to grind with a hand held tungsten grinder. I purchased a Sharpie from Arc-Zone....

Jattus, Are you creating an arbitrary waveform generator? It has been on the commercial market for about 30 years. Is your modulation occurring before the high current output generator? I have researched many welders for this feature, some with pulse frequency of 0.1 to 20 Hz, others from 1.0 to 2,0...

Otto The biggest benefit I found for a gas lens was when welding outside, where I had limited ability to control the draft near my weld. It was a big help with gas coverage. I prefer a gas lens now, but simply because I'm used to it, and it affords me more stick-out for difficult to reach welds, inc...

plain ol Bill,

What is the brand name of your plasma cutter X-Y table?Self made

SELF MADE!!! , now you have really peaked my interest, can you elaborate ? How about a few pictures ?

Wobulate

plain ol Bill, Nice sign ! : What is the thickness of the metal, and what type of metal did you use? What is the brand name of your plasma cutter X-Y table? What is the brand name and model number of your plasma cutter? How do you like the user interface of the plasma cutter X-Y table software progr...

I am going to edit this Thread to include data/info/opinions from other sources: I learned to TIG weld in 1974 on a Heli-Arc welder, no pulse, no AC balance, no square wave just AC or DC. Since this thread talked about the Precision TIG 225 I thought I would comment as I am an owner of this welder (...

Congratulations Jody, I found you when I was researching to purchase a new TIG welder. I soon became the proud owner of a few TIG Fingers. Someday it would be great to meet you face-to-face and talk welding for a few hours. Thanks for all that you do, the welding world is truly a better place becaus...
