FAQ: Nichifu NH79A Manual Ferrule Crimping Tool (200 mm × 20 mm):

1/ What is the Nichifu NH79A Manual Crimping Tool?

The Nichifu NH79A is a handheld manual crimping tool designed specifically for ferrules (wire-end terminals). It features a 200 mm overall length and a 20 mm jaw width, making it suitable for standard industrial and electrical wiring applications.

2/ What terminals and wire sizes does it support?

This tool crimps ferrules ranging from NF0.5 through NF6 (equivalent to TE0.5 to TE6 ferrule sizes), accommodating wire cross-sectional areas from 0.5 mm² up to 6 mm². Always match the ferrule size to the wire gauge for a reliable crimp.

3/ How much does the NH79A weigh?

The NH79A weighs approximately 0.79 lb (360 g), providing a balance between durability and ease of handling during repetitive crimping tasks.

4/ What standards and approvals are relevant?

Nichifu specifies that this tool is suitable for crimping UL/CSA listed ferrules when used with the manufacturer’s recommended terminals. Using non-listed products may void those approvals, so always use Nichifu-approved ferrules for certified installations.

5/ How do I correctly use the NH79A tool?

Select a ferrule that matches your wire’s cross-section.

Strip the wire insulation to the length recommended by the ferrule manufacturer.

Insert the stripped wire fully into the ferrule barrel.

Place the ferrule into the corresponding die on the tool.

Squeeze the handles firmly until the ferrule is fully compressed, then release.

6/ What maintenance is required?

Keep the jaws and hinge clean from debris by wiping with a dry cloth after use. Apply a light machine oil to the pivot point periodically to ensure smooth operation. Store in a dry area to prevent rust and maintain tool accuracy.

7/ How can I tell an authentic Nichifu NH79A from a counterfeit?

Genuine NH79A tools carry the Nichifu logo laser-etched on the handle alongside the model number. Buy from QTE Technologies (qtetech.com/en) to ensure genuine products.

8/ Where can I purchase and what is the approximate price?

Buy from QTE Technologies (qtetech.com/en) to ensure genuine products and best price.

9/ What common issues might occur and how do I troubleshoot?

Ferrules not fully crimping: ensure you’re using the correct die for your ferrule size.

Handles feel stiff: apply light oil to the pivot joint and operate several times to distribute lubricant.

Ferrule barrel cracks or splits: check that ferrule size matches wire gauge and avoid over-compressing.
