In this video, we are TIG welding 11 ga cold rolled steel and using different diameters of filler rod.
The first joint was welded using 3/32" filler rod at approximately 120 amps.
A second lap joint was also shown using 1/16" at slightly lower amperage.
In Brad Goodman's video on full penetration aluminum he used a Miller Dynasty that has all the features like waveforms and amplitude settings.
A member commented that he would like to see a similar video using a much simpler machine like the CK MT200.
I used a #5 clear cup (they film better) with...
This video deals with some of the most common mistakes when welding aluminum Tee joints and other aluminum fillet welds.
The Electrode Positive part of the AC arc is what breaks up the aluminum oxide layer on aluminum and allows the puddle to be clean and flow out well.
so let that cleaning action work for you before puddling dirty aluminum.
In other words...Dont puddle too quickly
