It truly amazes me on who can post something on-line and act like they know what they are doing. I've been welding for 10 years and that was literally the worst example of how to weld anything that I've ever seen. I'm pretty sure you could grab the square tubing with one hand and beat the end on the table. The two pieces would fall apart. The "helmet" was pretty bad, heat was wrong, and he even managed to call a tack a "Spotweld". I've spotwelded too and that's not what it is.
