Thank you for choosing our product! In order to take the most of your welder, please read the following instructions
carefully:
These Inverter’s machines are portable, air cooled and made to weld electrode and TIG Lift in direct current (DC). It
allows welding with rutiles, basic, stainless steel, cast iron electrodes and Cellulosic. In TIG, it allows to weld most of
metals except aluminium and alloys. It is protected for a use on electric generators (230V /+- 15% or 400V/+-15
%).
POWER SUPPLY – START UP
•
The machines delivered with a 230V socket /16A plug type EEC7/7
must
be plugged on a 230 V (50-60Hz) with
earth. The machines delivered with a 400V/16A three-phase type EN 60309-1
must
be plugged on a 400V three-
phase with earth. The machines equipped with a “Flexible Voltage system” must be plugged between 110V and
240V (50-60Hz)
with
earth. The absorbed effective current (I1eff) is shown on the machine, for maximal using
conditions. Check that the power supply and its protection (fuse and/or circuit-breaker) is compatible with the
necessary current during use. In some countries, the change of plug can be necessary to allow a use at maximal
conditions. For intensive use, preferably select a 20 A plug for the single phase products from 160A. The welder
must be installed so that the mains plug is accessible.
•
The start-up is done by pressing the ON / STAND BY.
•
The device turns into protection mode if the power supply tension is over 265V for the single phase models (the
screen displays ) or 460V for the three phases models (the screen displays ). Once in protection mode,
you have to unplug the device and plug it back on a socket delivering the correct tension.
•
These are A-class 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.
•
Do not use the machine in an area containing metallic conducting dust
ELECTRODE WELDING (MMA MODE)
•
Apply the usual welding rules.
•
Leave the machine connected to the supply after welding in order to let it cool down.
•
Thermal protection : thermal protection indicator turns on and the cooling time is about 2 to 5 min according to
external temperature.
•
Your machine is equipped with 3 specific functions to Inverters :
The Hot Start
(adjustable mode, see below) increases the current at the beginning of the welding.
The Arc Force
(adjustable mode, see below) increases the current in order to avoid the sticking when
electrode enters in melted metal.
The Anti Sticking
allows you to easily withdraw your electrode without damaging it in case of sticking.
Selection of MMA Mode and intensity setting :
- Select the MMA position with the selector.
- Adjust the wished current (display ) using the key .

Advice : low Hot Start : for thin metal sheets – high Hot Start for metals that are difficult to weld
(dirty or oxidized parts)
