WM BLITZ VIDEO #16 How to TIG Weld Cold Rolled Steel - Corner and Lap Joints

There is nothing special or difficult about tig welding 11ga cold rolled steel but I enjoy using it for videos because its readily available from jflf.org in kits for the boy scout merit badge. Even amazon has some 11ga cold rolled welding practice pieces for sale but the last kit I ordered from amazon was thinner than 11ga is supposed to be. 

11ga makes for some good practice and is more forgiving than thinner metal.

I used the CK worldwide mt200 AC DC tig welder and the smooth foot pedal along with super flex hoses on the 17 style torch make it fun to use.

I used a clear jazzy 10 cup for the corner joints and a ceramic 12 furick cup for the lap joints.  

The jazzy 10 would have been fine for all of it, but I like to experiment sometimes so I used a 12 for the laps.

Settings are listed in the video but I am listing here too...
