I can attest to woods flamablity. I was welding on a piece last night [before I here the choir, it was because I needed a square jig, and I was watching what I was doing, quickly snuffing out the flames] and every single time I pressed the trigger, a new flame popped up. I nearly grabbed for the extinguisher once or twice.. I have wood in my welding area, but I am extremely careful to cover everything, with multiple lays of plastic, hanging infront of it, so everything bounces back at me, rather than the wood.
A welding cart of wood= BAD idea.. I am an excelent carpenter... but I save it for making COFFEE TABLEs.. and not things around intense heat. The only way I was able to weld on my wooden bench, is because I know how to properly treat the wood, to perserve moisture. Even then I had a small flame pop up.. but the glove quickly snuffed it.
Also, if you ever decide to add a gas tank to the welder(can be done by adding a different gun, and using different wire.. probably more than its worth, but still possible) you DO NOT want fire to be near compresseed cylinders, ranging from 1-3000psi... lets put it this way... enough to go through a cinderblock wall... and still rip your leg off on the other side..
If you want to ignore our advice, then so be it, we won't offer any more, leave you to your own devices... but if you were smart, you would heed our advice.. maybe I am preaching to the choir, or a brick, but our advice IS VALID...
I can see the headlines too: "Family Dead, Freshman Puke failed to heed warnings"
