I used my Thermal Arc 185TSW to practice weld some .095-ish aluminum sheet
today. This is the first time I've used this (or any TIG) machine to weld
aluminum and I'm wondering if it should be making the noise it is.
It's considerable noisier than when I'm welding steel, with a "stuttering"
type of noise that changes when I change the wave frequency. I'm assuming
this is normal, but I figured I'd better ask... Is it normal?
