Description given on Youtube:
this is a video I made on how I like to weld aluminum pipe. I simplify the process for anyone wanting to learn.
Hopefully this video will shed some light on how to get proper penetration on aluminum.
for this video I set my TIG up old school. I was running 60 htz for the frequency and 45% dcep cleaning.
I was running my Alphatig Ahp200x for all the welding. Its a good machine for home use.
