EQUIPMENT DESCRIPTION (FIG-1)
The machines provide Inverter welding current designed for electrode wedling (MMA & TIG) in direct current (DC).
The MMA process allows to weld all types of electrodes : rutile, basic, stainless and cellulosic.
TIG welding requires gas shield protection of pure gas (Argon).
These products can be fitted with a remote control (ref. 045675) or a foot pedal (ref. 045682).

POWER SWITCH
The IMS FLEX 280A CEL is supplied without a plug and equipped with «Flexible voltage» technology and as such needs
to be connected to an electrical earthed installation supplying between 110V and 480V single-phase or three-phase
current (50-60Hz). This machine must only be used with a three phase electricity supply system with four wires and
one earthed neutral.

* WARNING ! If connected via a single-phase plug, the unused wire must be insulated to make sure it never makes contact with the other ones.
The absorbed effective current (I1eff) is displayed on the machine, for optimal use. Check that the power supply used
and its protection (fuse and/or circuit breaker) are compatible with the current required by the machine. In some
countries, it may be necessary to change the plug to allow the use at maximum settings. The user has to make sure
that the plug can be reached.
The devices turn into protection mode if the power supply tension is below or above the 15%. When this is the case,
the screen displays an error code.
• Turn the main switch (5) to the «I» position to turn the machine on and to «0» to turn it off. The device is switched
on by pressing the «
is in operation.
Fan :
- In MMA mode, the fan is always running.
- In TIG mode, the fan works only during welding, then stops after the machine has cooled down.
CONNECTION TO A GENERATOR
These machines can work on generators as long as the auxiliary power matches the requirements below:
- The voltage must be AC, always set as specified, and the peak voltage below 400V,
- The frequency must be between 50 and 60 Hz.
It is imperative to check these requirements as certain generators can create high voltage peaks that can damage these
machines.
