GYS NEOPULSE 400 G Pulsed MIG/MAG Welding Power Source
Pulsed MIG/MAG power source with a separate wire feeder
The GYS NEOPULSE 400 G, reference 014497 is a digital pulsed MIG/MAG power source built to work with a separate wire feeder. GYS designed it for heavy and demanding industrial applications, with more than 100 synergic curves and a rated 400 A at 60% duty cycle. It is supplied without accessories; the NEOFEED-4W wire feeder, cooling unit and trolley are separate references.
Besides MIG/MAG it covers MMA DC and pulsed MMA with basic, rutile and cellulosic electrodes up to 6 mm, TIG DC with lift ignition and pulse, and gouging up to 6.5 mm.

The optional NEOFEED 4W feeder, reference 014527 is rated 500 A at 60% and 460 A at 100%, feeds wire at 1 to 22 m/min with four driven 37 mm rolls and takes spools from 5 kg / 200 mm up to 18 kg / 300 mm.
Welding modes and traceability
The datasheet lists six MIG/MAG modes: Standard Dynamic, Standard Impact, Standard Root, Pulsed, Modularc and Manual, plus SPOT and DELAY tack modes and 2T/4T trigger control. In synergic mode the welder selects material, gas and wire diameter and the machine sets the starting parameters, which remain adjustable.
For quality documentation the machine calculates arc energy according to EN 1011-1, ISO/TR 18491 and QW-409, records welding steps for traceability under EN ISO 3834, and stores 500 programs that can be saved to a USB key. Calibration of the welding accessories corrects the displayed voltage and the energy calculation. An optional SAM interface connects it to a robot or automated system.
Building a complete NEOPULSE set
The datasheet also lists the practical details that matter on a shop floor: a reinforced metal case with non-slip rubber pads, four rings or brackets for lifting and positioning, intelligent fan management to cut power consumption and dust intake, internal lighting of the drive roll and wire reel, and a window for checking how much filler wire is left. Two optional remote controls, digital or analog, allow the settings to be changed away from the feeder. Machine and synergic updates are loaded by USB key.
Because the 400 G comes as a bare power source, a working set needs the NEOFEED 4W feeder, an interconnection cable, a torch, earth cable and, for liquid-cooled torches, the NEOCOOL cooling unit (ref. 032750). GYS lists air- and liquid-cooled interconnection cables from 1.8 m to 20 m. The power source needs a three-phase 400 V supply with 32 A delayed protection.
