More Information under Terms of Delivery

Welding device for daily mobile use.
MIG (GMAW) welding with shielding gas and electrode.

Adjustable functions and important device elements:

MIG / MAG welding machines are used for metal arc welding, in which a protective or mixed gas protects the weld against the harmful effects of oxidation. A high working speed, low warpage and clean seams, which only require minor rework, make MIGMAG welding machines particularly efficient and economically profitable.
Gasless FLUX CORED WIRE MIG MAG WELDING – is possible with all our MIG ST IGBT welding machines. You need for it special welding cored wire (not included in the scope of delivery).
Automatic wire feed speed. During MIG / MAG welding, the wire electrode is automatically unwound from the spool and pushed by a wire feed unit through a several meter-long hose packages to the power contact tube in the torch.
IGBT Technology for all our ST models we rely on the powerful IGBT transistors, which are used in the power engineering of our ST devices. The advantages are high blocking voltage and robustness.
MIG/MAG - power section has a stepless adjustable throttle (Inductance). This choke smoothes the welding current and changes the current rise rate to improve weld quality and precision...
Startstrom MMA/ARC-Stick Electrode welding can be used under almost all conditions and therefore MMA welding can be described as a universal process in the welding industry.
Anti-Stick-function prevents sticking of the stick electrode.
In the case of a sticking of the electrode to the workpiece, the welding current is switched off.
Hotstart – automatic voltage increase at start-up for better welding results.
Startstrom Smart Cooling
Fast cooling fan allows maximum power consumption and increases the operating time (ED) of the unit.
Startstrom Overheating -Control (O.C. - Overheating Control).
Overheat protection starts as soon as the unit is overloaded. A yellow indicator light turns on and goes out as soon as the unit has cooled down again.
The single-phase alternating current is to be protected in the household with a 16 A fuse.
The welding machine is connected directly to the single-phase alternating current (AC) 230 V (+ -15%), 50/60 Hz operation.
Startstrom ST-Guard-Housing is ergonomic, robust and operationally reliable:
- Sturdy sheet steel housing, - Shock-proof, - Hard plastic formwork,
- Control panel conveniently accessible and easier to operate, - Intelligent fan guide.


Excellent quality due to fully digital inverter technology

The welding machine MIG 200 ST IGBT has the most advanced inverter technology IGBT (Insulated Gate Bipolar Transistor). The resultant special features such as high speed and precision of the control give the devices their excellent quality in welding and cutting.

Partial mechanical metal arc welding (MSG), optionally as MIG (metal welding with inert gases, EN ISO 4063: process 131) or MAG welding (metal welding with active, reactive gases, EN ISO 4063: process 135) is an arc welding process The melting welding wire is continuously fed by a variable speed motor. The usual welding wire diameters are between 0.8 and 1.2 mm (less than 1.6 mm). At the same time as the wire feed, the protective or mixed gas is fed to the welding site via a nozzle with approx. 10 l / min (firing formula: protective gas flow rate 10 l / min per mm of welding wire diameter). This gas protects the liquid metal under the arc from oxidation, which would weaken the weld. In the case of metal-based gas welding (MAG), either pure CO2 or a mixed gas of argon and small amounts of CO2 and O2 (Corgon) are used. Depending on their composition, the welding process (baking, droplet size, splash losses) can be actively influenced; In the case of metal inert gas welding (MIG), argon is used as rare gas, more rarely also the expensive noble gas helium. The MAG process is primarily used in steels, while the MIG process is preferred for non-ferrous metals.
Optionally welding cored wires, also known as tube welding wires, can be used for metal arc welding (with active gas welding EN ISO 4063: process 136, with inert gas EN ISO 4063: process 137). These can be provided in the interior with a slag former and optionally alloying additives. They serve the same purpose as the caps of the stick electrode. On the one hand, the ingredients contribute to the sweat volume, on the other hand they form a slag on the welding bead and protect the seam against oxidation. The latter is particularly important in the welding of stainless steels, since the oxidation, the "tarnishing" of the seam must be prevented even after the torch has been advanced and thus the protective gas bell has been passed on.

MMA / ARC-Stick electrodes Hand welding
The great advantage of electric welding is that the materials do not have to be preheated and can be welded directly to the desired positions. It is also possible to connect workpieces of different thickness without problems. For example, a 10 x 10 mm square steel can be welded with a 3 mm sheet. In practice, such connections are constantly present, for example in the construction of a railing, in the manufacture of a fence or in the repair of agricultural machines, where heavy U-shaped profiles are often welded with thinner parts. The widest field of application of electrode welders is, of course, in industry, in the craft sector, in DIY and construction.

The control technology fits different
Applications and greatly improves the welding performance

MIG / MAG welding machine works with a melting welding wire, which is continuously tracked by means of a motor. In order to adjust the thrust speed, the amount of abrading filler material can be adjusted variably by the user. MIG welding uses inert, non-reactive gases, and active gases are used in MAG welding.

Voltage regulator (only for MIG MAG welding)
If the length of the electric arc changes (e.g. because the distance between workpiece and torch is increased) so the resistance of the electric arc increases. This causes less temperature to be generated in the electric arc. As a result, the wire melts slower. By increasing the voltage can counteract this temperature loss and the wire melts back to normal.

DC
DC direct current (german: Gleichstrom).
- For non-alloyed and low alloy steels, stainless steel, copper, brass and so on.
- Not for light metals, e.g. Aluminum suitable (no AC).

Bedienfeld

All our MIG welding machines are also suitable for MMA / E-hand welding.

Anti-stick
Shortly before the end, the system releases the set maximum current, which prevents sticking and annealing of the electrode. In the case of a sticking of the electrode to the workpiece, the welding current is switched off. The electrode does not glow and can easily be detached from the workpiece.

Hotstart
Prevents the sticking of the stick electrode by short-term superimposition of the set welding current and warms up the weld seam start faster.


Overheat protection
Overheat protection goes on when the unit is overloaded. A yellow indicator light turns on and goes out as soon as the unit has cooled down again.
