The Volta precision crimping tool covers cable sizes from 2.5mm² to 10mm² and is built for MC4 and MC4-compatible solar connectors. A ratchet mechanism delivers 1.2 tonnes of crimping force and will not release until the crimp cycle is complete, so every connection is finished to the same depth.

Key features

• Cable range, 2.5mm², 4mm², 6mm² and 10mm² (AWG 14/12/10/8)
• Ratchet action, releases only once the crimp is fully complete
• Crimping force, 1.2 tonnes with minimal hand effort
• Magnetic locator, holds the terminal in position in the die before crimping
• Emergency release, lets you free the tool if it jams mid-cycle
• Handle, ergonomic anti-slip grip
• Size and weight, 215mm long, 0.70kg

Product overview

A ratchet mechanism is what separates a reliable crimping tool from a basic one. It locks the handles together and only opens once the die has travelled its full distance, so the crimp depth stays consistent no matter how tired your hands are by the end of a rooftop. Partial crimps are a common cause of MC4 connection failure, especially on 10mm² cable where more force is needed to seat the terminal properly.

The magnetic locator keeps the terminal aligned in the die before you squeeze the handles, which matters when you are working at height or in an awkward position.

Applications

Use this tool for assembling MC4 and MC4-compatible connectors, terminating solar PV cable on residential and commercial installs, and building extension leads in the field from 2.5mm² up to 10mm² cable.
