Which tool is recommended for removing insulation from electric wire?

Wire strippers are specifically designed for the purpose of removing insulation from electric wire safely and effectively. This tool features sharp blades that can cleanly cut through the outer insulation while preserving the integrity of the copper or other conductive materials inside. The design often includes different sized notches to accommodate various gauges of wire, ensuring that the right amount of insulation is removed without damaging the wire itself.

When using wire strippers, the technician can precisely control the amount of insulation removed, which is critical for making secure electrical connections. This precision helps to prevent shorts and ensures that the wiring maintains its proper electrical properties.

Other tools listed do not have the specific functionality for this action. A wheel puller is intended for removing gears or wheels; a welding helmet is protective gear used during welding, and a wood chisel is primarily for carving or shaping wood. None of these serve the purpose of stripping insulation from electric wires, making wire strippers the clear and appropriate choice.
