Please note this device uses 4 different welding methods. Read below how these work and what the advantages are.
1 and 2 MIG and MAG welding
The difference between MIG and MAG welding
The difference between MIG and MAG welding can already be deduced from the full names. MIG stands for Metal Inert Gas and MAG stands for Metal Active Gas. The only difference between these welding techniques is the type of shielding gas used.
For example, in MIG welding, argon or mixtures of argon with hydrogen gas and helium are used as inert gas. MAG welding uses an active gas, such as carbon dioxide (CO₂). For example, an inert gas does not react with the molten bath, while an active gas does. The MIG welding technique is therefore used when no chemical reaction is desired.
MIG/MAG welding
So the only difference between MIG and MAG welding is shielding gas. The welding process is otherwise exactly the same. That is why MIG/MAG welding is designated as 1 technique. With MIG/MAG welding we use an electrode that melts slowly. A constant voltage is therefore present, unlike, for example, TIG welding where a constant current is used.
With MIG/MAG welding, a wire is continuously mechanically fed during the welding process. This welding wire is fed by the welding torch and used by the welder to lay the weld. During welding, a plasma arc is created. The wire in this plasma arc serves as an electrode and melts, thereby also serving as an additive material.
3. MMA welding
MMA welding is a welding method in which the filler rod in the electrode holder serves as the welding electrode. The arc burns between the rod and the workpiece.
The difference with other welding methods is that the filler rod that serves as the welding electrode in MMA welding becomes shorter and shorter during the welding process. With TIG and MIG/MAG welding, the length of the electrode remains constant. Therefore, the distance from the welding torch to the workpiece must always remain constant. In MMA welding, however, the electrode holder must always be moved towards the workpiece to keep the distance between the electrode and the weld pool constant. This is a special challenge in MMA welding.
4. FCAW welding
In this welding process, the welding electrode is a hollow wire that is filled with a fine welding powder that consists of substances that form shielding gases during heating/melting in the molten bath, which protect the liquid metal against oxygen penetration. The wire filling also creates a fast-setting slag that supports the molten pool in vertical and overhead welding positions and reduces spatter and jets, so that relatively large currents can be worked. The slag layer can usually be easily removed mechanically after welding.
There are many different types of welding wire available for this welding process, with differences between the fillers used, but also in terms of wire production (welded or folded).
Some welding machines also offer the option of connecting a stick for electrode welding, so that the welder can easily switch between welding processes.
