PEARL 190.2 PEARL 190.4 XL
DESCRIPTION
Thank you for chosing this machine. To get the best use from your machine, please read the following carefully :
The PEARL 190.2 / PEARL 190.4 XL is a semi-automatic welding unit; it is ventilated for semi-automatic welding (MIG
or MAG) It is capable of welding steel, stainless steel and aluminium, and with it’s « synergic wire speed » function
adjustment is easy and fast.
ELECTRICITY SUPPLY
The absorbed current (I1eff) is indicated on the device at maximum usage. Check that the power supply and its
protection (fuse and/or circuit breaker) are compatible with the current needed for use. In some countries, it might be
necessary to change the plug to allow maximum performance. The device must be installed so that the mains socket
is accessible.
Do not use an extension cable with a diameter of less than 1.5mm². PEARL 190.2/PEARL 190.4 XL is delivered with a
16amp plug (TYPE CEE7-7), and the machine features a highly efcient PFC and Flexible Voltage technology.
This machine must be connected to an EARTHED power supply between 110V and 230V, 50/60 Hz, and protected by
a 16A circuit breaker (32A on 110V 30mA trip)
- When using on a voltage below 165vEFF this will limit the current draw to 16A
- If the voltage is <85V or >265V, the machine will not start
- Protected against surges - PEARL will shut off automatically in case of overvoltage

DEVICE PRESENTATION (FIG I)
1 : Push-button setting for welding mode (Manual or
Synergic).
2 : Wire Reel holder - Ø 100/200 mm (PEARL 190.2) or
200/300mm (PEARL XL 190.4)
3 : European standard torch connection.
SEMI-AUTOMATIC WELDING FOR STEEL / STAINLESS STEEL (MAG MODE)
PEARL 190.2 & PEARL 190.4 XL can weld Steel wire 0.6/0.8/1.0mm, and Stainless Steel of 0.8/1.0mm
The machine is originally equipped to function with Ø 0.8mm Steel, or Stainless Steel wire. The contact tube, the
groove of the roller and the sleeve of the torch are all compatible with 0.8mm wire. Should you wish to weld 0,6
wire, use a torch of maximum 3m long. You will also need to change the contact tip (Fig II A). The wire reel is reversable (0.6 / 0.8mm) and will need to be inserted so that the gure 0.6 is visible.
For use with Steel, the gas requirement is argon + CO2. (Ar+CO2).. The proportion of CO2 required will vary depending on the use. For Stainless Steel, use the combination of 2% CO2 For specic gas requirements, please contact
your gas distributor. The gas ow in steel is between 8 and 12 Litres/minute depending on the environment.
SEMI-AUTOMATIC WELDING FOR ALUMINIUM (MIG MODE)
This machine is capable of welding Aluminium wire of 0.8 and 1.0mm
For use with aluminium, the gas requirement is pure argon (Ar). For the specic gas requirements please contact
your distributor. The gas ow in Aluminium is between 15 and 25 Litres/minute depending on the environment, and
the experience of the welder.
The differences between use with Steel and Aluminium are :
- Rollers : Use specic rollers for Aluminium welding.
- Pressure : Adjust the pressure of the drive rolls to prevent the wire being crushed.
- Capillary Tube : Only use a capilliary tube for welding with Steel or Stainless Steel.
- Torch : Use a special Aluminium Torch with a teon sheath to reduce friction. DO NOT cut the sheath close to the
joint, it is used to guide the wire from the the rollers.
- Contact tube : Use a special aluminium contact tube specic to the diameter of wire being used.
4 : Earth clamp socket.
5 : On/Off switch.
6 : Solenoid Valve.
7 : Power Cable (2.10 m)
GASLESS WIRE WELDING
PEARL 190.2 & PEARL 190.4 XL is capable of gasless wire welding up to 0.9mm, provided that the polarity is reversed (g C) respecting a maximum pressure of 5Nm. For parameters of use, please refer to the instructions indicated
on page 7. Welding gasless wire with a standard nozzle can lead to overheating and deterioration of the torch. It is
recommended to use a “No Gas” nozzle (ref. 041868), or remove the genuine nozzle (Fig. III D).

Advices
This mode allows quick and easy welding and has been optimised for welding angled pieces.
To obtain an identical butt weld, it is recommended to slightly reduce the setting of metal thickness.
The arc length: Lengthens (0 -> +9) or shorter (0 -> -9) to allow more or less penetration of the
metal. The display will show the changes to allow more comprehensive setting. If you are welding
for the rst time, we recommend you set the arc length to 0.
Choice of welding angle : only on SYNERGIC mode
