START-UP
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 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.

On the digital display in the MIG/MAG welding mode, the actual welding current value is shown during the welding process. It is worth noting that the actual welding current value is influenced by several factors, including the wire diameter used, the set welding voltage on the power source, the wire feed speed set on the feeder mechanism, the shielding gas used, the material and thickness of the welded workpiece, among others. After the welding process is completed, the actual welding current value remains displayed on the machine’s screen for 8 seconds, allowing the welder to view the current value.

Regulator 3 on the front panel is multifunctional and is responsible for:

selecting any function in the current welding mode (turning left and right);
setting the value of the selected parameter (press the regulator and turning left or right);
reset all functions to factory settings of the current program of the current welding mode (press the regulator and hold for more than 12 sec.).

Button 2 on the front panel of the unit is responsible for selecting the welding mode.

SWITCHING TO THE REQUIRED FUNCTION

If the machine has an active protection system against unauthorized access to the function menu, then when turning the regula tor 3, adjustment of the value of the main parameter of the current welding mode occurs, also this means that the function menu is locked. To unlock it, press and hold down regulator 3 for more than 3.5 seconds. When unlocking, the indicator displays an image of opening lock, indicating the process of unlocking the function menu. After successful unlocking, when turning the regulator 3 to the right or left, the current name of the function and its value will be displayed on the digital display.

Similarly, by pressing and holding the regulator knob 7 on the wire feed unit for more than 3.5 seconds, the menu is unlocked, and the name and value of the function for the current welding mode are displayed on the digital screen 8. By pressing the regulator knob 8 and turning it left or right, you can switch between functions and parameters of the mode and also adjust their values.

SWITCHING TO THE REQUIRED WELDING MODE
Pressing button 2 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 them to the standard factory settings, it is enough to press and hold down regulator 3 for more than 10 seconds (ignore the animation of the lock symbol). The scoreboard will start counting down 333…222…111 and when “000” is reached, all settings of the selected program of the current welding mode will be updated to factory settings. Reset parameters for each program each welding mode are made separately. This is provided for convenience, so as not to reset individual settings in the other programs and welding modes.
Similarly, you can reset the parameters of current welding mode on the wire feeder by using the regulator 7.

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 4 on the welding current source (or button 9 on the wire feeder).
Then the LCD displays the current program number, which can be changed up or down by turning the regulator 3 (or the regulator 7 on the wire feeder) to the right or left. It is necessary to confirm the program selection by pressing the corresponding regulator knob 3 or 7.
