re: Anyone know anything about Airgas?

I thought airgas was mostly in the welding industry. I know they are buying up a ton of local welding supply shops. Only experience I have of them is a family friend who owns a large welding outfit paid a bill about the time airgas was taking over and the payment wasn't entered by the old company so airgas continues to pursue collections despite him providing proof he already paid it. He just found another supply shop.

This probably isn't helpful but at least you know my story.
