Full Digital CO2/MAG/MIG Welding Machine



ネクストフルデジタル溶接機 YD-400NE1


Catalog coming soon
* In addition to this product (welding power source), a wire feeder, remote control unit, torch, and gas regulator are required for welding.

Key functions

  • Significantly reduced spatter
  • Easy access to the necessary information

  • Wire feeder meticulously designed for ease of use


Achieving a high-quality finish like an expert

This model significantly reduces the amount of spatter compared to conventional models. High-quality welding is now possible in a wide current range.

Knowing when to perform maintenance

The Welding Concierge function displays operation instructions as well as points to check before welding operation on the LCD. Users can rest assured since they will be notified when they have to carry out maintenance.

Making the welding process visible

Welding Navigation selects the recommended welding conditions when parameters are input, including the workpiece material, plate thickness, and joint type. Even inexperienced users and those who have been away for a long time can set optimal welding conditions.

Strengths and Features

400NE1 welding performance

Significantly reduced spatter and stabilized welding performance

With its 100 kHz inverter, even lower spatter welding can be achieved compared to conventional models. Especially for aluminum welding, this model demonstrates high performance in response to requests, such as the need to achieve a beautiful bead appearance and increase the amount of penetration at the start of welding.

<Welding conditions>
Welding current: 220 A, Welding voltage: 21.6 V, Welding speed: 50 cm/min

Welding Concierge allows users to easily access the necessary information

This function prompts workers to input frontline conditions and their requests such as the improvement of weld start quality on the LCD, facilitating welding parameter adjustments that require experience and expertise.
Since the configuration of the required devices and the specific procedures for wiring before starting welding are displayed on the LCD, even inexperienced users can safely operate this product.

More information on Welding Navigation


The touch panel type color LCD monitor can display a wealth of information, thereby allowing users to check the configuration of the required devices and the specific procedures for wiring before starting welding.

Welding Navigation facilitates the setting of welding conditions

The main unit is equipped with Welding Navigation. The welding conditions are automatically determined by setting various conditions such as a joint shape and plate thickness on the LCD. Furthermore, the use of the Plate Thickness Command will enable users to set the welding conditions simply by entering the plate thickness.*
Even individuals who are not regularly engaged in welding or have limited experience can easily set welding conditions.
* Available for fillet welding of workpieces of the same thickness.


The new wire feeder combines safety and easy-to-use features

With a full cover structure that protects the drive and live parts, users can install the feed roller or replace the pressure roller without using any tools.


A lightweight aluminum frame (16 kg*) and a large handle for enhanced portability have been adopted. The new digital remote control unit can be operated even while wearing gloves.

* Air-cooled type
