"Coat hangers even come with varnish "flux" coating to "enhance" the gas shielding."
Thanks for pointing that out Carl. With that new information I'll leave the argon cylinder off when I'm doing tig work and save on consumables. I've tried using coat hangers when welding aluminum, but for some reason I haven't quite perfected the technique yet even with the argon turned on. Do you have any idea what the problem might be?
Maybe Dean could ask his welding instructor. Dean?
