Welding Tips and Tricks

I came by a wall mounted 3/4 HP Dayton Flume system with a snorkel arm and it pulls about 80% of the smoke out. I just came by a 1 HP Lincoln Mobiflex® 100-NF that I'm thinking of using under my table to pull smoke away too. I like to weld outside when ever I can. All ideals welcome.

Don't have any hands on advice but here is a deal on the unit you mentioned. Its used but who cares at that price.
