Hi there!
Been doing hobby welding since about 2014, with an HTP Mig200 welder, and just very recently started with TIG, with an used HTP Invertig 201 - their first gen 
My first project way back 2014 was of course a welding table: Two slabs of 36" long, 12" wide, 1/2" thick hot rolled, which gave me a working size of 2’ by 3’. Of course the top warped since I didn’t know back then much yet (I claim I only know a “little” more now) but it served its purpose for many projects for me and my close friends.
Now with Tig, I am tired of the warped/non flat surface of my welding table so decided to start shopping around, and after a month or so of reviewing, watching videos, etc., just ordered the ArcFlat welding table
I know there is a long wait, but I am looking forward to finally having a nice and flat welding surface
