The current waveforms are advanced square wave, soft square wave, sine wave, and triangle wave.
They all have slightly different looks, sounds and characteristics.
Some waveforms are supposed to be better for thin metals, others for thicker metals.
There is another advanced feature on a very few tig inverters and it is called advanced AC pulse.
Advanced AC pulse is when the current is alternated between DCEN and AC.
American Welding Society AWS D17.1 is the specification for Aerospace Fusion Welding Applications. This Specification provides details for welding certification as well as production welding.
A typical test required to certify a welder in aluminum is the 2f tee fillet weld test.
The awning was built inside a shop using mostly tig, but for installation, a spool gun running off a generator helped move things along
There is a lot to talk about.
things like tungsten electrodes..type and size ( i like 2% lanthanated for everything and 3/32 takes care of most of my daily welding)
shielding gases ...argon is best to start but if you begin to specialize in thicker aluminum, it might make sense to use a blend of ...
