Available evidence
A public robotic-cell family page may list robot payload, positioner kilograms, span and swing beside a photograph of a guarded bay. Use that information to write questions about construction. Require the manufacturer to confirm whether the kilogram rating includes fixture mass and center-of-gravity offset, and to say whether the quote is an integrated cell or a robot arm plus a power source sold as loose items. Catalog cycle time without load, clamp, weld and unload steps is not first-article evidence. Connected load in kilowatts, supply frequency in hertz and compressed-air demand for torch cleaning belong in the same reply if those utilities are in scope.
What does the source not establish?
Public ranges do not establish that a particular cell has been taught on your tank seams, that a brand-appointed reseller relationship exists, or that installation, training and commissioning are included. They also do not fix the single-station loading side or the light-curtain layout against your floor plan. Fume extraction listed as an option on a family page is not an included line until the offer names it.
