The welding unit is designed exclusively for MMA welding, tungsten-arc inert- gas (TIG) welding, as well as metal-arc inert-gas welding/metal active gas welding (MIG/MAG). Other use of the machine is considered undue. The manufacturer is not responsible for damage cause by undue use of the machine. Intended use of the machine implies adherence to instructions of this operating manual.

INSTALLATION REQUIREMENTS
The machine must be placed so as to ensure free inlet and outlet of cooling air through vent holes on the front and the rear panels. Take care that metal dust (for example, during emery grinding) does drawn directly into the machine by the cooling fan.

POWER CONNECTION
The standard welding machine is rated for:

Mains voltage is 220V (-27% +18%) – for MultiPRO-250 model;
Three-phase mains voltage is 3x380V or 3x400V (for MultiPRO-270 and MultiPRO-350-15-4-400V models), three wires are dedicated for this. Safety rules when working with welding equipment require grounding of the unit housing. There are two ways to do this: 1) by using the fourth wire in the mains yellow-green cable (international marking standard); 2) by using a bolted terminal on the rear wall of the unit (a stricter grounding standard, used in the CIS countries).

Caution! When the unit is connected to a mains voltage higher than 270V (for MultiPRO-250) or 450V (for MultiPRO-270/350-15-4-400V models), all manufacturer’s warranty obligations become invalid! The manufacturer’s warranty obligations also become invalid in case of an erroneous connection of the mains phase to the source ground.
The mains connector, the cross-sections of the mains cables, as well as the mains fuses need to be selected based on the unit technical data.

SELECTING THE DEVICE MENU LANGUAGE
To select/change the menu language of the device, hold down button 3 and turn on the device. After that, the language selection menu will be displayed on the screen. You can select the desired language using the buttons 2. 2 seconds after selection, the machine will continue working in the corresponding language.

SELECTING AND SETTING THE FUNCTIONS OF THE MACHINE

If you do not press the buttons on the front panel, the unit displays the value of the main parameter of the current welding mode on the digital indicator on the left:

in the MMA mode – welding current;
in the TIG mode – welding current;
in the MIG/MAG mode – welding voltage.

During the MIG/MAG welding, the left display shows the current value of the current resulting from the following factors: used wire diameter, set voltage value at the source, set wire feed speed on the feeder, gas used, material and the thickness of the workpiece to be welded, etc. The value is shown within 8 seconds after the end of welding, this is necessary for the welder to be able to double-check the current value, without any outside help. In the MIG/MAG mode, the digital indicator on the right side shows the value of the wire feed speed in “m/min”. Button 3 on the front panel of the unit is responsible for selecting the source function in the current welding mode, and button 9 is responsible for selecting the function of the feeder in MIG/MAG mode. Button 4 on the front panel of the unit is responsible for selecting the welding mode. Buttons 2 on the front panel of the source are responsible for changing the current value on the digital indicator on the left.Buttons 11 on the front panel of the feeder are responsible for changing the current value on the digital indicator on the right.

SWITCHING TO THE REQUIRED FUNCTION
If the unit has a system of protection against unauthorized access to the function menu, then if you press button 3 on the source, no changes are made on the left indicator, i.e., this button is locked. To unlock, hold it down for more than 3.5 seconds. When unlocking, the indicator displays an image of opening locks, indicating the process of unlocking the function menu. After successful unlocking, by pressing button 3, the current name of the function and its value are displayed on the digital display.

Caution! After releasing button 3 after 2 seconds, the screen will return to the main parameter of the current welding mode. While the display is showing the current function, its value can be changed up or down using buttons 2. Alternatively, by quickly pressing and releasing button 3, you can switch to the next function, in a circle.
Caution! If you hold down button 3 for more than 10 seconds, then the countdown will appear on the display 333… 222… 111 …; release the button before this time expires, so as not to reset all the settings of this mode to the standard factory settings.
Similarly, by pressing button 9, the digital indicator on the right displays the graphic name of the current function of the wire feeder, and immediately after releasing it, the current value of this function is displayed for 2 seconds. You can change the value up or down with buttons 11.

SWITCHING TO THE REQUIRED WELDING MODE
Pressing button 4 leads to switching to the next welding mode in a circle, this can be seen on display 1 on the front panel.

RESET ALL FUNCTIONS OF THE WELDING MODE USED
Situations may occur when the unit’s settings have somewhat confused the user. In order to reset their values to the factory default, use the same button 3, used to enter the function menu. To reset the settings, simply hold down button 3 for more than 10 seconds (ignore the animation of locks). The scoreboard will start counting down 333…222…111 and when “000” is reached, all settings of the current welding mode will be updated to factory settings. Resetting parameters for each welding mode is performed separately! This is provided for convenience, so as not to accidentally reset individual settings in the other two modes.
Similarly, you can reset the parameters on the wire feeder using button 9.

CHANGE PROGRAM NUMBER IN CURRENT WELDING MODE
In each MMA, TIG, and MIG / MAG welding mode, it is possible for the user to save up to 16 different presets. The current preset (program) number is displayed in the upper right corner of the LCD of the source on the front panel. At the moment of the first switching on of the machine, the program is always under No. 1 for each welding mode. All changes in the setting of the machine in this welding mode and the current program number are saved. To switch to another program number and start setting again from the basic parameters, just press button 3 and if the function selection menu is locked, then the LCD displays the current program number, which can be changed up or down using buttons 2. If the function selection menu is not locked, for example, the user just before that changed the additional parameters of the functions, then it is necessary to lock the function selection menu by holding button 3 for more than 3.5 seconds, in the same way as when unlocking, when the LCD will show closing locks, after this operation the menu will be locked and now you can try again to change the program number using button 3. In this case, all the parameters of the previous program will be saved and you can always return to it again.
