Power Supply - GYS NEOPULSE 400 G Mode D'emploi

ASSEMBLY AND ADVICE
The connection between the welding machine and the wire feeder must be done while the power supply is off.
Open the access panel and pass the intercon-
nection cable through the circular opening at
the back of the wire feeder.
Pass the interconnection cable through the
trolley.

POWER SUPPLY

• This machine is fitted with a 32 A socket type EN 60309-1 which must only be used on a three-phase 400 V (50 - 60 Hz) power supply fitted with
four wires and one earthed neutral.
The absorbed effective current (I1eff) is displayed on the machine, for optimal use. Check that the power supply and its protections (fuse and/or
circuit breaker) are compatible with the current needed by the machine. In some countries, it may be necessary to change the plug to allow the use
at maximum settings.
• The machine is designed to work on a 400V +/- 15% power supply. It switches to protection mode if the power supply voltage is below 330V RMS
or over 490V RMS. (To indicate this default, the wire feeder's screen displays an error code, check the instruction manual).
• Power up the machine by switching the on / off switch (4 - FIG 1) to the I position, and stop it by switching it to the 0 position. Warning! Never
disconnect the power supply while the machine is charging.
• Cooling fan management : This welding machine features an intellingent cooling fan system, in order to minimise noise. The fans will adjust their
speed depending on the current use and ambient temperature. They may be switched off in MIG mode.
CONNECTION TO A GENERATOR
The machine can work with generators as long as the auxiliary power meets the following requirements:
- The voltage must be AC, with a 400V ±15% RMS value and a peak voltage below 700V,
- The frequency must be between 50 and 60 Hz.
It is imperative to check these requirements, as many generators generate high voltage peaks that can damage these machines.
USE OF EXTENSION LEADS
All extension leads must have an adequate size and section, relative to the voltage of the machine.
Use an extension lead that complies with national safety regulations.
