3. GENERAL DESCRIPTION
The synergistic welding machine DIGIMIG 200 PULSE is used for manual welding of steel and non-ferrous metals. It
enables welding with MMA (coated electrode), MMA with pulse, TIG Lift, TIG Lift with pulse, and MIG / MAG. Welding with
the MIIG / MAG method can be carried out with the use of single and double pulse. The MIG / MAG method can be used
in manual and synergic mode, simplifying its operation and allowing the welding machine to be used by people with less
experience and hobbyists. Due to the change of polarity, the device allows welding with the MIG / MAG method using
both standard wires in a protective gas shield and self-shielding flux-cored wires.
The device allows you to connect a Spool Gun (SG) with a mini wire feeder and a D100 spool of steel or colored wire.
The device is made in IGBT technology, which allows for a significant reduction in the weight and dimensions of the welding
machine and an increase in efficiency while reducing energy consumption.
The welder is used in closed or roofed rooms, not exposed to
direct exposure to atmospheric influences.

Work cycle
The duty cycle is based on a 10-minute period. 60% duty cycle means that after 6 minutes of operation, a 4-minute break
is required. Duty cycle of 100% means that the device can work continuously without interruption.
Attention! The heating tests were carried out at the ambient air temperature. The duty cycle at 20ºC has been
determined by simulation.
Level of security
The IP defines the degree to which the device is resistant to the ingress of solid and water contaminants. IP21 means
that the device is adapted to work in closed rooms.
Overheating protection
The IGBT module is protected against overheating by a protective system that turns off the power to the welding
machine. After a few minutes, the device cools down to a temperature that allows it to be switched on again
automatically. Do not disconnect the power supply during this time, because the continuously operating fan cools the
internal heat sinks of the device in order to reduce the temperature faster. After restarting, remember to limit the
welding parameters for further continuous operation of the device.

VRD function
The VRD function lowers the voltage in no-load condition. The correct voltage is not restored until just before the arc is
struck. This minimizes the risk of electric shock, but in some cases may make the arc difficult to ignite.
ARC FORCE function
The ARC FORCE function allows you to adjust the dynamics of the welding arc. Shortening the arc length is accompanied
by an increase in the welding current, which stabilizes the arc. Decreasing the value gives a soft arc and a smaller fusion
depth, while increasing the value causes deeper penetration and the possibility of short arc welding. With a high value of
the ARC FORCE function, it is possible to weld with the minimum arc length and high electrode melting speed
HOT START function
The HOT START function is popularly called hot start. It works when the arc is struck, causing the welding current to
temporarily increase above the value set by the welder. HOT START is designed to prevent the electrode from sticking to
the material and is a great help when striking the arc. When welding small parts, it is recommended to disable this
function, as it may cause burnout of the welded material.

7.3 SYN MIG, PULSE, D-PULSE and SPL MIG method
During MIG welding, the device can operate in synergic (SYN MIG, PULSE, DPULSE) and manual (SPL MIG) modes. The
synergic mode allows less experienced users to choose welding parameters. In this mode, the device automatically
selects the welding current and wire feed speed depending on the type of material to be welded and the diameter of the
electrode wire. It is possible to correct the welding voltage.
Manual mode allows the user to choose the welding voltage and wire feed speed depending on the needs.
Depending on the selected control mode and welding method, adjustments can be made according to the table below.

Correction of welding voltage in synergic modes
After setting the welding current in synergic modes, it is possible to correct the welding voltage. After setting the
welding current using the knob (P), you can adjust the welding voltage using the knob
(NS). To check the percentage change in voltage in relation to the value set according to the synergic program, press the
GAS (C) button. By turning the knob (L) it is possible to further correct the voltage. To return to the voltage value display,
press the GAS (C) button again.
Inductance regulation
Adjusting the inductance allows you to optimize the arc characteristics depending on the thickness of the workpiece and
the welding method and conditions. This function is useful during MIG / MAG welding of thin elements, preventing them
from burning out and during brazing of galvanized elements. Changing the inductance value also reduces the amount
of welding spatter during
CO shielded welding2. The greater the inductance value (+), the number of spattering decreases, while the value is
negative (-), the amount of spattering increases. The optimal setting of the inductance value depends
on several factors and may differ from standard recommendations, therefore it should be selected experimentally
during welding tests.
Adjusting this parameter also enables brazing of thin (up to 3 mm) galvanized elements with wires made of CuSi3 copper
alloy in pure argon or in some cases
Ar / CO mixtures2 in the ratio (82/18).

Pulse width
The width of the pulse is the duration of the pulse, it allows you to adjust the depth of penetration. Increasing the
width increases the penetration depth, reducing the amount of heat introduced into the material, reducing the risk
of burning through thinner sheets or smaller components.
Lower pulse width values should be used for higher currents. A larger pulse width should be used for small currents,
for example a width greater than 50% should be used for currents below 100A.

High-quality argon should be used: 4.8 and higher recommended
Additionally, depending on the working conditions, you can set the inductance value, which affects the shape of the
weld, the depth of penetration and the number of spattering during welding.. It should be taken into account that the
recommended welding parameters in synergic mode apply to typical welding materials from the selected group
and recommended shielding gases. When welding various alloy materials, the operating parameters may not be
optimal and require adjustment of the settings. For this reason, the synergic mode should not be treated as a
universal parameterization proposal, but as a starting point for fine adjustment of settings.
The manual SPL MIG function, i.e. manual selection of parameters, is especially useful for braze welding. Using the three
welding parameters, set the optimal set to obtain the correct weld. When selecting parameters, choose low voltage
values and high wire feed speeds. It is recommended to use argon as a shielding gas, but gives good results
also using a mixture of argon and CO2 (82/18). Due to the required shape of the weld, the inductance should be selected
experimentally depending on the thickness and type of material to be welded.
Copper-based binders are most often used as an additional material. These are wires marked as CuSi3 or SG –CuAl.
It is recommended to use a handle with a length of no more than 3 m, equipped with a Teflon insert.
8. WELDING OF ALUMINUM ALLOYS
In synergic mode, you can choose between two programs for aluminum welding. The programs were selected for
welding with ALSi5 type ER 4043 wires, mainly intended for foundry aluminum, and with AlMg5 type ER 5356 wire, which
is suitable for welding all types of structures and sections. Welding aluminum is not a simple activity, it requires
experience, knowledge and certain practices from the welder, which will facilitate the execution of welds on aluminum
elements. In the synergic program, the device selects the output parameters for the appropriate material grade and
wire types. Depending on the needs, appropriate voltage and inductance corrections should be made to obtain the
desired effect.
First of all, you should remember about a few important things that significantly affect the appearance of the weld and
have an impact on the correct course of the welding process.
Before starting welding work on aluminum parts, complete the following steps:
Device:
Make sure that the feed rolls are designed to work with aluminum: the groove is U-shaped and dedicated to the
correct diameter of the welding wire. Using the wrong rollers will cause wire deformation and problems in the
welding process.
