- Protection against acess to dangerous parts from solid bodies of a ≥12.5mm diameter and,
- Protection against the rain inclined at 60% towards the vertical.
These devices can be used outside in accordance with the IP23 protection index.
The manufacturer does not incur any responsability regarding damages to both objects and persons that result from an incorrect
and/or dangerous use of the machine.
MAINTENANCE / RECOMMENDATIONS
• Maintenance should only be carried out by a qualified person.
• Ensure the machine is unplugged, and that the inside fan has stopped before carrying out maintenance work. High Voltage
and Currents inside the machine.
• Remove the casing 2 or 3 times a year to remove any excess dust. Take this opportunity to have the electrical connections checked by a qualified
person, with an insulated tool.
• Regularly check the condition of the power supply cable. If the power cable is damaged, it must be replaced by the manufacturer, its after sales
service or an equally qualified person to prevent danger.
• Ensure the ventilation holes of the device are not blocked to allow adequate air circulation.
Do not use these machines to unfreeze pipes.
INSTALLATION – PRODUCT OPERATION
Only qualified personnel authorized by the manufacturer should perform the installation of the welding equipment. During set up, the operator must
ensure that the machine is unplugged. Connecting generators in a series or a parallel circuit is forbidden.
HARDWARE DESCRIPTION (FIG-1)
The TIG 300 DC is a three phase inverter welding unit to be used with refractory electrodes (TIG) in direct current (DC) and electrode welding (MMA). .
TIG welding requires gas shield protection of pure gas (Argon).
The MMA process can wel all types of electrodes : rutile, basic, stainless and cast iron.
The TIG 300 DC can be equipped with a remote control (ref. 045675) or a foot pedal (ref. 045682).
The TIG 300 DC can be equipped with an automatic command (CONNECT-5).

POWER SUPPLY – STARTING UP
• This machine is delivered with a 5 pin three phase plug (3P+N+PE) 400V 16A type EN 60309-1.
The TIG 300 DC is powered by a 400V (50 - 60 Hz) three phased earthed power supply. This hardware must only be used with a three phase electricity
supply system 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 protection (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 user has to make sure that the plug can be reached.
• The machine ie designed to work on a 400V +/- 15% power supply. • The device turns into protection mode if the power supply tension below
340V RMS or over 460V RMS. To indicate this default, the screen displays an error code.
• The start is done via an on / off switch (7) set to I, and the stop is done by switiching it to O. Attention ! Never disconnect the power supply
when the machine is on.
• Fan: in MMA mode, the fan works nonstop. In TIG mode, the fan works only when welding, then stops after cooling.
CONNECTION ON A GENERATOR
The machine can work with generators as logn as the auxiliary power matches these requirements :
- The voltage must be AC, always superior to 400Vac ±15%, and the peak voltage below 700V,
- The frequency must be between 50 and 60 Hz.
It is imperative to check these requirements as several generators generate high voltage peaks that can damage these machines.
