1. GENERAL INFORMATION
The invertor-rectifier welding unit PATON®VDI MINI is designed for direct-current manual arc
welding (MMA). This welding unit’s series "MINI" is intended for exacting users who need a
portable fully functional welding unit with a rated current of up to 150 A. Such a current is sufficient
for welding by using any welding electrodes from Ф1.6 mm through Ф4.0 mm in diameter, at a load
factor not less than 40 percent, allowing welding works to be performed in household conditions, such
as at country sites, in small workshops, or in garages.
Due to the increased frequency of voltage at the input of the rectifier transformer of the welding unit,
the weight and overall dimensions of the transformer are significantly reduced as compared with other
welding units with similar output characteristics.
The basic advantages of the PATON®welding unit are the following:
1. The welding unit is protected against long-time fluctuations of power supply voltage and
ensures welding arc stabilization when the input voltage of the unit changes in the range of 170
V through 260 V. It should be noted that welding at a minimum voltage of 170 V is allowed only
by using an electrode not more than Ф3 mm in diameter;
2. The welding unit is rated for operation with a standard power supply system. Due to the higher
efficiency coefficient of the welding unit, the power consumed by the unit is reduced by 50
percent as compared with other similar welding units;
3. The welding unit is easily operated due to the optimal operating load factor in operation of the
unit at the rated current. Due to this, it is possible to perform welding works comfortably
using 3 mm welding electrodes at the rated current;
4. The enhanced reliability of the welding unit in operation in dusty environment;
5. All the printed-circuit boards with electronic elements of the welding unit are impregnated with
two layers of high-quality varnish in order to provide the high reliability of the welding unit
within its service life;
6. The possibility to adjust welding current smoothly;
7. The Improved welding arc stability.

The welding unit is allowed for outdoor operation. The internal electrical and electronic elements of
the welding unit are protected against moisture but are not protected against atmospheric condensate
drops.
ATTENTION!When operating the welding unit in cold season, after the unit
was switched off and cooled, condensate may appear inside the unit, so switch
on the welding unit only 3 –4 hours after the switching off!!!

7 | Pa g e PATON®VDI SERIES MINI DC MMA
For this reason, do not switch off the welding unit if it is anticipated that the unit is to be switched on
not later than 4 hours after switching off.
Install the welding unit so as not to block or cover the ventilation slots on the front and rear panels of
the unit. Prevent ingress of metallic particles (for example, when grinding the weld) sucked into the
welding unit by the unit ventilator.
ATTENTION!!!After fall from a height, the welding unit might be a source
of electrical shock. Install the unit on a firm stable surface.
2.3 CONNECTION TO A POWER SUPPLY SYSTEM
The commercial welding unit is rated for an input power supply voltage of 230 V (- 26% / +13%).
ATTENTION!!! If the welding unit has been damaged in the result of
increase of the input power supply voltage of the welding unit to more than 270
V, possible in the case of large unbalance of phase voltages in the standard
power supply system, the warranty of the manufacturer of the welding unit will
be invalid.
The power supply connector, cross-section areas of the power cable conductors, and power supply line
fuses should be selected with consideration for the technical characteristics of the welding unit.
2.4 REQUIREMENTS FOR AN ELECTRICAL OUTLET
ATTENTION!!! The parameters of an electrical outlet for the power supply
of the welding unit must correspond to the power supply voltage and
consumption current of the unit (see "Technical characteristics"). Connect the
welding unit to an electrical outlet that is rated for a three-wire plug with a
grounding conductor!!!
3. MANUAL COVERED-ELECTRODE ARC WELDING PROCESS (MMA)
3.1 PREPARING THE WELDING UNIT FOR OPERATION
Preparation the welding unit for MMA operation:
1. Insert the plug of the electrode cable into socket A (+) of the welding unit;
2. Insert the plug of the grounding cable into socket B (-) of the welding unit;
3. Connect the grounding cable to the workpiece;
4. Connect the power cable of the welding unit to the outlet of the power supply
system;
5. Set switch 3 to position 1 (switching on).
6. The device is ready for use. Enjoy Your work.

8 | Pa g e PATON®VDI SERIES MINI DC MMA
ATTENTION!!! In the manual arc welding process, after switching on the
welding unit by switch 3, the welding electrode is under voltage. Do not allow
the electrode to contact current-conducting or grounded parts, such as the
casing of the welding unit etc.
3.2 INCREASED-CURRENT ARC STARTING HOT-START
The advantages ensured by the increased-current arc starting function are the following:
1. Improved arc starting even when low-quality electrodes are used;
2. Better base metal penetration during the arc starting period and, as a result, the lesser number
of defects associated with incomplete penetration;
3. Prevention of slag inclusions.
What is achieved by:
During the short time interval of arc starting, the welding current increases by 33 percent of the
welding current set by default (see Figure 1).
Example: The electrode diameter is 3 mm.
The set welding current is 90 A.
The current at the increased-current arc starting stage is 90A + 33% = 120 A.

3.3 REDUCED WELDING VOLTAGE FUNCTION ARC-FORCE
The advantages ensured by the forced arcing at reduced welding voltage function are the
following:
1. Improved arc stability in the short arc welding mode;
2. Improved transfer of molten metal drops into the welding pool;
3. Improved arc starting;
4. Reduced probability of electrode sticking.
What is achieved by:
When the arc voltage is lower than the minimum voltage required for stable arcing, the welding
current increases by 30 percent relative to the set current (see Fig. 2)
Figure 2. Forced arcing at reduced welding voltage ARC-FORCE
3.4 PROTECTION AGAINST ELECTRODE STICKING “ANTI-STICK”
At the stage of arc starting, the electrode can stick to the workpiece and, as a result, the electrode can
be damaged due to overheating.
If the electrode has stuck to the workpiece, the welding current decreases within 0.6 … 0.8 s after the
sticking. The temporary reduction in the welding current makes it easier for the welder to peel off the
stuck electrode. After separating the electrode from the product, the welding process can be resumed
without any problems.
4. MAINTENANCE
ATTENTION!!! Before maintenance, switch off the welding unit and
disconnect the power cable from the outlet of the power supply system. Wait
for about 5 minutes until static charges in the electrical circuits of the unit
disappear, and then perform the maintenance operations. After the completion
of works with the welding unit, apply to the unit a plate with a warning text
prohibiting switching on the unit.
