The work that looks hardest to me here is the sheet metal. The shelves and the curved tank retainers were cut by hand with a plasma torch, using both straight and circle-cutting guides. Freehanding curves in thin sheet rarely goes well, so in my view leaning on those two guide types is a smart way to keep the shapes clean and true.
The frame itself came together in a tidy order. Square tubing was measured, marked and cut on a chop saw plus a portable band saw mounted on a stand, then wiped down with naphtha before anything was joined. Pieces were aligned on a modular fixture table, the frame was MIG welded, and the seams were smoothed with an angle grinder. The dark green paint went on with an air spray gun, and all four casters were welded straight to the base.
Plenty of small details stand out. The top tier carries the Power MIG 210 MP and the Square Wave TIG 200 side by side, the middle tier holds coiled cables, the foot pedal and a helmet, and storage tubes keep filler wire close. At the back, a rack carries two cylinders fitted with flowmeter regulators, their restraint bars held by threaded thumb bolts, with one bottle clearly labeled ARGON, COMPRESSED UN1006.
One open question for me: loaded with two machines and two bottles, how manageable is it to steer on four swivel casters? I would also love to see how the maker's week-long TIG course in Cleveland, Ohio shows up in the finish work.
