3 questions I get asked a lot are:
I first learned about the primeweld Tig225x on 6061 youtube channel.
That guy is a very talented welder and he did a review where he gave it some high marks.
So when PrimeWeld ordered some TIG fingers from me, I asked them to send over a demo unit for me to try out. These are the videos I shot with that unit and more are on the way to make sure each setting is explained.
The video below explains and demonstrates what the AC balance setting does on aluminum and what happens when you have too much cleaning or not enough
The video below shows a simple example of using AC frequency settings
Brad Goodman aka @deepsouthdimestacker shows how he welds aluminum lap joints using the pedal pumping method.
Pretty much all aluminum tig welders do a fine job on DC for welding steels.
It is AC where they seem to differ so that is why all these videos are focussing on the AC function....to show that this welder is a great value and welds aluminum really well.
