http://www.weldingtipsandtricks.com/welding-tubing.html http://weldmongerstore.com/ In this weeks video we are using tig pulse settings of 33 pulses per second to weld .032" (0.8mm) thick steel tubing for a bike frame. The manufacturer of the steel tubing recommends using weldmold 880 filler so in this video some of it is welded using weldmold 880 and some is welded with er70s-2 tig filler rod. http://welding-tv.com/the-store/
In this video I talk briefly about what TIG settings worked for me to butt weld thin walled aluminum tube. The tube is 0.375" od and 0.035" wall.
