I played around with the tig again tonight..
Here are my first tig welds with aluminum.. oddly enough i am finding aluminum easier to weld than mild steel which i guess isnt a bad thing.. i tried all settings tonight on the tig machine including different pulsing, and different size filler welds. you can see from the top down, i was working on getting my settings right and by the bottom everything wasnt too bad.. i would still love some pointers from people who do this everyday to point me in the right direction...i might actually try to stick two pieces together tomorrow.. i cant wait !!

i am getting a few big sheets of stainless on Monday to play around with as well.. freebee's are good.. Wink

I moved the tig holder to the other side. Makes hanging it way easier and doesn't interfere with the drawer...

Blasted and ready for some stainless steel tig work. Not sure if I am going to leave it blasted or polish it up. Have I told you I love this tig stuff?

Top and bottom of my filler rod holder for the side of my machine. I am going to weld in some dividers and ends on the lower piece. I also need to drill a few holes to let the dirt fall through.

after drilling out those holes I think one was enough. SS is hard compared to mild steel. Or at least these scraps are! I don't like how high the bottom sits so I am going to move it down onto the cart. These shots are using existing holes.

Not quite done, test fit:

we should go together on buying one more pvc tube and all the ends so we can make 4 more complete tig rod tubes and then split them so we can both have 6 in total..

My recommendation for TIG welding aluminum vs mild steel, is that when starting a weld you need to bring the amperage up quick on AL, once you get a nice shiny puddle then get moving! I find you can't "sit around" like you can with welding steel, SS is the same as AL in this regard.

Also in regards to pulsing, don't when you're first learning. Just get used to making a strong bead, then you can begin playing with pulsing (not sure if the Lincolns have an automated pulser?). The pulser or pulsing the pedal is just one more variable that might slow the initial learning process.

FYI my old chart that I created as a guideline:

www.aceengineering.ca/Temp/TIGWeldingChart.pdf

I usually set it to 10-20% above the max and then have enough resolution with the pedal and enough juice in reserve if needed.

That is a GREAT chart Conrad! I was searching for one last night and none of them seemed as complete as yours. Saved and printed out.

Our machines do have the pulse feature. I found it very handy last night with my SS.

I forget where I pulled all that data from, Miller being one source and somewhere else...that was 5-6 years ago. It will get you in the ballpark the majority of the time, the rest is just experience and usually you'll just fall back on the 0.001" = 1 amp and add another 10-20%. The most interesting part of the chart is the frequency for the aluminum welding, higher frequency focuses the arc, while as a lower frequency makes a less focused arc.

I would have posted it up earlier but I forgot I still had that on the old site!

Pulsing is nice as it freezes the puddle when it drops to the background current. Looking good guys!

I lowered the bottom of the filler rod holder and like it much better:



I also made a little holder on the other side for my consumables:





Now I just need to practice PRACTICE PRACTICE

I got nothing but the tags on the front with mine.

I sent an email off to Lincoln to get a manual (available on line) and the rest of the literature that comes with the unit.
