With steel it's not such a big deal, but when welding aluminum on a wood surface, apart from the fire hazard, as the wood heats up it starts out-gassing all kinds of stuff that will get sucked into your argon stream and contaminate your weld. So you could end up chasing your tail trying to get good welds. The watch word for TIG is clean clean clean and with aluminum even more so.
Long arc, short arc, heliarc and in-the-dark!
