They are according to other principles of their selection and as far as the parameters of a set of synergistic can still be corrected by the system described

in paragraph 7.3.1, it adjustable parameters in manual mode can not be changed according to the rules synergistic.

Please note that after calling packet memory settings and change any welding parameter changes made will not be automatically saved in this package.

After a few seconds (8 seconds) the new settings are loaded to the cache device, but will not be stored permanently on a specific number of memory.

Will function, until you change one parameter, or after a reboot. To return to the settings stored, you must call them from a particular memory stored

number.

7.3.2.1 brazing

Function Manual, the manual selection of parameters is particularly useful for braze welding. Using the three welding parameters must be set optimal set

capable of producing a proper weld. When selecting parameters to be selected low and high voltage wire feed speed. It is recommended to use argon as

a shielding gas, but good results can also use a mixture of argon with CO 2 ( 82/18). Due to the required shape of the weld inductance should be selected a shielding gas, but good results can also use a mixture of argon with CO 2 ( 82/18). Due to the required shape of the weld inductance should be selected a shielding gas, but good results can also use a mixture of argon with CO 2 ( 82/18). Due to the required shape of the weld inductance should be selected

empirically depending on the thickness and type of material being welded. As additional material is most commonly used copper-based binder. These

wires are labeled CuSi3 or SG -CuAl.

It is recommended to use the handle of not more than 3m equipped with a Teflon cartridge.

7.3.3 welding of aluminum alloys

In synergy mode, you can select one of two programs for aluminum welding. The programs were selected for welding wire ALSi5 type ER 4043, primarily

intended for aluminum casting and wire AlMg5 type ER 5356, which is suitable for welding all types of constructions and profiles. Welding aluminum is

not a simple function, the welder requires experience, knowledge and behavior of certain practices that will facilitate the welds on aluminum elements.

Device in a synergistic adjusts the output of the corresponding grade materials and types of wires. Depending on your needs, make the appropriate

adjustment of the voltage and the inductance to get the desired effect.

It should first of all remember a few important things that greatly affect the appearance of the joint and affect the correct welding process.

Before starting work on the welding of aluminum components, follow these steps:

Device:

• Ensure that the feed rollers are designed to work with aluminum groove is shaped like the letter "U" and are dedicated to the appropriate

diameter of the welding wire. Using the wrong rollers will cause deformation of the wire and the problems in the welding process.

• Ensure that the feed rolls are not too tight. Excessive tension wire may cause feeding problems.

• Make sure that the handle is equipped with a teflon cartridge guide intended for aluminum. The use of steel elements used to feed the steel

wire will cause feeding problems.

• Make sure that the contact tip is the right size and is suitable for aluminum wire

• It is worth mentioning the contribution of part of the wire guide in the tray to the version of Teflon, which improves wire feed, as is the case in

the torch.

Workplace:

• Pay attention to proper site preparation welding work: hall should be clean, have good ventilation and should maintain a low humidity.

The presence of iron oxide dust or dusts from the steel elektropowietrznym gouging is unacceptable.

• Position for welding aluminum industrial vacuum cleaners should be vacuumed once a day, after work.

• Clothing should be clean welders gloves can not be greasy.

19

Preparation of material:

• Spot welding, clean and degrease just before welding,

• Aluminum components degreased by wiping with a clean cloth moistened with a degreasing formulation, e.g.,. Acetone (alcohol is not a good

degreasing agent, discourage the use of it in the purification of aluminum).

• Remove all traces of heavy oxides before welding. Normally this operation is performed manually or mechanically by means of a steel wire

brush. In the case where the material is heavily contaminated, it may be necessary to use the grinder.

• After appropriate preparation of the surface, as soon as possible to perform the welding process.

• If the non-welded part must remain for a longer period of time, protect her brown wrapping paper and taped with adhesive tape.

Proper storage of welding wire

• Welding of aluminum should be stored in a clean, dry environment, preferably in its original packaging.

• The wire need not be stored in conditioned rooms, it is best suited to storage under conditions of low humidity. Do not dip the wire in the

water.

• If the wire, which is relatively cold is introduced into the room in the hot, humid day and once opened, it is possible that humid air will

contaminate the wire. Therefore, in the case of storage in a climatic chamber wire, be sure not to unpack the wire until it is heated and adapt

to the ambient temperature.

• After working the wire should be removed from the tray and secured in a plastic bag for the next use.

For welding of aluminum alloys, as the shielding gas must be used pure argon high-quality class, preferred not less than 4.8. The gas flow should be

selected according to the thickness and travel speed. Good welding results are achieved when the process occurs in the direction of the left side.

7.3.4 Welding of stainless steel

The synergistic device has been developed for welding of the most popular type of stainless steel alloys 308LSi and the like and used for shielding gas

mixture of argon + CO 2 in 82/18 ratio. The welding parameters and other high alloyed steels used other mixtures of shielding gases may require an mixture of argon + CO 2 in 82/18 ratio. The welding parameters and other high alloyed steels used other mixtures of shielding gases may require an mixture of argon + CO 2 in 82/18 ratio. The welding parameters and other high alloyed steels used other mixtures of shielding gases may require an

adjustment of the welding parameters.

8. INITIATION ARC

8.1 MMA

1. Touch electrode to the workpiece, and short rub tear.

2. In the event of initiation of the arc electrodes, wherein the sheath when solidified, creates a non-conductive slag, the pre-clean the tip of the

electrode by repeatedly impact against a hard surface until the metal in contact with the work piece.

8.2 TIG

1. Unscrew the valve handle TIG, that there was a flow of protective gas.

2. Gently tap the electrode material is welded to break the electrode from the welded material by tilting the holder in such a way that the gas

nozzle touch material.

3. Once the arc is struck straighten the handle and start welding.

8.3 MIG / MAG

1. Bring the holder parts to be welded, so that the distance between the nozzle and the welded parts was approx. 10 mm.

2. Press the button on the torch and start welding.

that time interrupt the power supply, since the continuously operating fan cools the heat sinks inside the unit to more quickly reduce the
temperature. After restarting, be sure to limit the welding parameters for further continuous operation.

Error wire feeder. Make sure that the spool of wire is attached correctly, or, on the spool is a wire or established are appropriate rollers and the
pressure roller is set correctly. The error message will disappear after the cause of the error. The display shows the last parameter settings
before the error occurred.
