DESCRIPTION
Thank you for choosing this GYS machine! To get the most out of your purchase, please read the following
information before using the machine.
The TIG 207FV/208 is a portable, single phase, ventilated Inverter welding unit to be used with non-
consumable electrode (TIG) in direct (DC) or alternative (AC) current. TIG welding requires a gaseous
protection (Argon). In MMA mode, it allows you to weld with any kind of electrodes: rutile, basic, stainless
steel or cast iron. The TIG 208 has an integrated liquid cooling system. The TIG 207FV-208 can be equipped
with a remote control or foot pedal. (This is available separately as an option)They work with a single phase
230V input for the TIG 208, a single phase input spread between 85V to 265V for the TIG 207 FV. They are
protected for a use on electric generators.
POWER SUPPLY – STARTING UP
• This device is delivered with a plug 16A type CEE7/7. The 208 must be connected to a socket 230V (50-
60Hz) WITH earth. The 207FV integrates a « Flexible Voltage » system and can be used on a
power
supply variable between 85V and 265V (50 – 60 Hz) WITH earth. The absorbed current (I1eff) is
indicated on the device, for its maximum setting. 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 starting up is made by pushing on the standby button .
• The device turns into protection mode if the power supply tension is over 265V. To indicate this default,
the screen displays
. Once in protection mode, you have to unplug the device and plug it back on a
socket delivering the correct tension.
• Ventilator: in MMA mode, the ventilator operates permanently. In TIG mode, the ventilator only operates
during the welding phase, and then stops after cooling.
• These are Class A devices. They are designed to be used in an industrial or professional environment. In a
different environment, it can be difficult to ensure electromagnetic compatibility, due to conducted
disturbances as well as radiation. They comply with the norm IEC 61000-3-12.
WELDING WITH COVERED ELECTRODE (MMA MODE)
Getting Started
• Connect the electrode holder and earth clamp to the corresponding sockets.
• Ensure that the welding polarities and intensities indicated on the electrode packaging are observed.
• Remove the electrode from the electrode holder when the machine is not in use.
Integrated welding assistance
Your device is equipped with 3 specific functions :
Hot Start gives an adjustable* overcurrent at the beginning of welding.
Arc Force delivers an overcurrent which avoids sticking when the electrode enters the welding pool.
Anti-Sticking allows easy removal of the electrode in case of sticking.
Selection of process and current setting
1- Select MMA mode 2- Select the wanted current thanks to the potentiometer.
Adjustable* Hot Start
The Hot Start is adjustable (between 0 and 60%) within the limit of 160A.
1- Press and hold the “Hot Start” button.
2- Select the required setting.
N.B. : the display "HI" indicates that the Hot Start is at maximum.
