The crafting grid is obvious, the box with the transparent ingot is for iron ingots only, and the furthest right box if for placing items that require use of the soldering station, at that point, the recipe will appear on the crafting grid, and only those items may be placed to duplicate the item.

So for coding purposes, I see no reason to include that, though I will include a picture on the soldering Station page.
