Inert welding gas. So oxygen is not in the weld or on it while cooling. Oxygen makes welds brittle and weak.
Pffft, we did contractor 55 gallon bags with rocket fuses stuffed inside and ran the wire back to the igniter. Wear ear protection hide behind a blast berm. lol. So much fun blowing out every window for blocks!! lol

We set #10 can on edge of table at shop class and had the torch dialed in snuffed out the flame and filled the can and touched it off... The can hit the ceiling and crushed up flat... 2 months later it came down on the teacher.... Then someone else did it but over did it and blew all the windows out... The top of the can took off .. Dude just stood there stunned wit the torch going...
