Re: Micro TIG welders
18-22 GA 1008 cold rolled as first choice or A36 pickled and oiled.
I should have some scrap suitable for cutting a weld to see penetration. Try and get some results over the weekend.

Re: Micro TIG welders

Re: Micro TIG welders
Drawing down what I have is interesting. Would at least let me see if I have a wire size issue or an alloy issue. I found some small wire from Gesswein in the diameters ddmckee mentioned.

Re: Micro TIG welders
1mm .040" 6061 aluminum. No filler since I cant find 6061 wire small enough. Tried Er4043 .030" MiG filler, but it's a bit too big to melt evenly. Best results have a crack across the weld which is...

Re: Micro TIG welders
As a side note:
carbon steel welds turn out great and are super easy. 18ga at 75 Watt-seconds is pretty strong and looks nice. A little bit more penetration would be nice.
Brass is very sooty/ugly...

Re: Micro TIG welders
Sunstone says the default ignition retracts the electrode at the same time the arc fires. There is an option to have the arc fire after the electrode has retracted. The final setting is "pre heat"...

Re: Micro TIG welders
They recently went up in price a bit so a system is 3-5k or so. Lampert is more.
That's the model I was planning on. It was out of stock for most of the year. With the recent price increases I...

Re: Micro TIG welders
Pulled the trigger on a sunstone. The Lampert is too expensive and hard to acquire.
The reps there were responsive and future support should be good. They recommended the microscope system which...

Re: Build an Excavator from Scratch
This is looking great. The beauty panels pulled it all together so well. The metalwork shows your high standards.
The hard pipes on the boom are a great detail.
