The DIGIMIG 200 HIT synergic welder is used for manual welding of steel and non-ferrous metals. It enables welding with
MMA (covered electrode), TIG and MIG/MAG methods. The MIG/MAG method can be used in manual and synergic modes,
simplifying its operation and allowing the welder to be used by people with less experience and hobbyists. By changing the
polarity, the device allows you to weld using the MIG / MAG method using both standard wires in a protective gas shield and
self-shielding flux-cored wires.

HOT START function
The HOT START function is popularly called a hot start. It works when the arc is struck, causing a temporary increase
in the welding current 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. In the case of welding small elements, it is recommended to
disable this function, as it may cause burnout of the welded material.

The button is active only during MIG.MAG welding. Pressing and
holding the button will cause the flow of shielding gas, releasing it will stop the flow of gas.
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
shallower depth of penetration, while increasing the value causes deeper penetration and the possibility of short arc
welding. With a high value of the ARC FORCE function, you can weld while keeping the arc length to a minimum and
the electrode melting speed high
Welding current
The button is used to select the welding method. Selection of the appropriate mode is confirmed by lighting of the
control diode.
VRD function
The VRD function lowers the no-load voltage. The correct voltage value is only restored just before the arc is struck.
This minimizes the risk of electric shock, but in some cases it may make it difficult to strike the arc.

Changing the inductance value also reduces the amount of welding spatter during welding in a CO2 shield. The higher the
value of the inductance (+) the less spatter, when the value is negative (-), the greater the amount of spatter. The optimal
setting of the inductance value depends on several factors and may differ from the standard recommendations, so it should
be selected experimentally during welding tests.

8. WELDING OF ALUMINUM ALLOYS
Argon
The welder has built-in synergic programs for selected materials, wire diameters and shielding gases in accordance with the
table below:
Designation
Aluminum welding is not a simple activity, it requires the welder's experience, knowledge and adherence to certain practices
that will facilitate the execution of welds on aluminum elements. In the synergic program, the device selects the output
parameters for the appropriate grade of materials and types of wires.
AL
0.6/0.8/0.9/1.0
Using three welding parameters, set the optimal set to obtain the right weld. When selecting parameters, choose low voltages
and high wire feed speeds. It is recommended to use argon as the shielding gas, but the use of a mixture of argon and CO2
(82/18) also gives good results. Due to the required shape of the weld, the inductance should be selected experimentally
depending on the thickness and type of the welded material.
MIX
In addition, depending on the working conditions, you can set the inductance value, which affects the shape of the weld, the
depth of penetration and the amount of spatter during welding. It should be taken into account that the recommended
welding parameters in the synergic mode apply to typical welding consumables from the selected group and the
recommended shielding gases. When welding different 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 precise adjustment of settings.
First of all, you should remember about a few important things that significantly affect the appearance of the weld and affect
the correct course of the welding process.
Inductance adjustment
Inductance adjustment enables optimization of the arc characteristics depending on the thickness of the workpiece and the
welding method and conditions. The function is useful during MIG/MAG welding of thin elements, preventing their burn-
through, and during braze welding of galvanized elements.
It is recommended to use a handle not longer than 3 m equipped with a Teflon insert.
0.8/0.9/1.0 Ar+CO2 (82/18)
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 deformation of the wire and problems in the welding
process.
Material
Adjustment of this parameter also enables braze welding of thin (up to 3 mm) galvanized elements with wires made of CuSi3
copper alloy in pure argon shield or in some cases Ar/CO2 mixture in ratio (82/18).
Aluminum (ER 5356)
In synergic mode, you can select a program for aluminum welding. The program has been selected for welding with AlMg5
wire type ER 5356, which is suitable for welding all types of structures and sections.
Depending on the needs, appropriate voltage and inductance corrections should be made to obtain the desired effect.
Shielding gas -
recommended
• Use high grade argon: 4.8 and above recommended
Manual MIG mode, i.e. manual selection of parameters, is especially useful for brazing.

next use.
• Aluminum welding stations should be vacuumed with industrial vacuum cleaners once a day, after
in original packaging.
• The wire does not need to be stored in air-conditioned rooms, it is best to store it in low humidity conditions.
Do not soak the wire in water. • If a wire that is relatively cold is brought into a room on a hot,
humid day and immediately opened, it is possible that the humid air will contaminate the wire. Therefore, if
the wire is stored in an air-conditioned room, remember not to unpack the wire until it has warmed up
and adapted to the ambient temperature. • After finishing work, the wire should be removed from the
feeder and secured in a plastic bag for
1. Open the valve on the TIG torch so that the shielding gas flows out.
Workplace: • Pay
attention to the proper preparation of the welding work place: the hall should be clean, well ventilated
and the air humidity should be kept low. The presence of iron oxide dust or dust from electro-
air gouging of steel is unacceptable.
• Make sure the contact tip is the correct size and is designed for aluminum wire. • Consider replacing part
of the wire guide in the feeder with a Teflon version that improves wire feeding like a welding gun.
• Aluminum welding wire should be stored in a clean, dry environment, preferably

2. In the case of arc initiation with electrodes whose coating, after solidification, forms a non-conductive
slag, initially clean the tip of the electrode by hitting it several times on a hard surface until metallic
contact with the welded material is obtained.
• Make sure the handle is equipped with a Teflon guide insert designed for aluminum.
• After proper surface preparation, the welding process should be carried out as soon as possible. •
If a part must remain unwelded for an extended period of time, protect it with brown kraft paper and tape it.

cause a feeding problem.
Material preparation:
• The welding area should be cleaned and degreased just before welding,
• Aluminum elements should be degreased by wiping with a clean cloth soaked in a degreasing agent, eg
acetone (Alcohol is not a good degreasing agent, we advise against using it when cleaning aluminum).
• Remove heavy oxide residues before welding.
Normally, this is done manually or mechanically with a steel wire brush. If the material has become heavily
soiled, it may be necessary to use a grinder.
9. ARC INITIATION
• Make sure the feed rolls are not too tight. Excessive wire tension can
• Welders' clothes should be clean, gloves should not be greasy.
For welding aluminum alloys, pure argon of high quality class, recommended not less than 4.8, should be used
as a shielding gas. The gas flow should be selected according to the thickness and welding speed. Good
welding results are achieved when the process direction is counterclockwise.
