The die pattern is what forms the crimp and it belongs to the terminal rather than to the conductor. A four-mandrel die closes a ferrule from four sides into a square section. A hexagonal die closes it into six. A terminal crimped in the wrong pattern looks finished and has less contact area than it should. The pattern is stated per plier rather than being judged from a photograph of the jaw.
Capacity is quoted as a conductor cross section rather than a wire gauge, and the plier covers a range rather than one size. A conductor below the range is not gripped by the crimp; one above it is not fully closed, and both fail as a connection rather than visibly. Reading the conductor size before the plier is what avoids a crimp that passes inspection by eye.
Action decides whether the crimp is complete. A PreciForce plier will not release until the full pressure has been reached, which removes the operator judgement that causes most poor crimps on a hand-squeezed tool. MultiCrimp forms carry more than one die on the same jaw for mixed terminal work.
Solar connectors have their own tooling because the connector and the current both differ. MC4 crimping pliers at 220mm to 250mm work to that specification rather than being a general crimper used on a solar terminal.
