Weldability Range, What does this value mean?

[winter39]

I curently have a material specification sheet that has some parameters for Resistnace Spot Welding USIBOR 1500P material. It states the minimum current (12.3 kA), maximum current (13.7 kA) and weldability range (1.9 kA). What does the weldability range value mean?

Does anyone have any insight on the term "weldability range"?
Thanks

Did some research on this, and the closest match I could find in resistance welding terminology is a brochure on a Miller Aerowave Hybrid AC/DC Constant Current Squarewave Arc Welding Power Source. In their description, they refer to Welding Amperage Range. In the context of weldability, this may be the same definition used by another manufacturer. Weldability refers to the ability to produce a sound weld deposit.
