The term wire welding, also known as continuous wire welding, refers to a welding method that does not involve replacing the electrode every time it is needed, unlike electrode welding.
This is made possible by the wire being used during operations, making possible logistical interruptions very rare.
A traditional wire welding machine is characterised by the following components:
The continuous wire welding machine is used to make small or large welds, in any possible field; from car bodies to fixtures and metal structures.
However, it is best suited for work in covered areas, as the action of the wind could affect the quality of the end result.
Generally, continuous wire welders have a fairly easy operation: a small electric arc is generated between the point to be welded and the wire from which the weld pool will be obtained.
To further increase safety during operations, the torch emits a gas that protects the parts involved during welding, so that the weld pool, once in contact with the air, does not oxidise too quickly, affecting the final result.
Depending on the different characteristics of the gas used, we can distinguish between 2 different types of welding: MIG and MAG.
For the first case, an inert gas is used, and is used for welding light alloys, stainless steel and copper.
In the second case, only carbon dioxide escapes from the torch, which plays an active role in the welding process.
If, on the other hand, no gas is used for welding, the process is called MOG.
This category includes a selection of the best continuous wire welding machines, from which it will mainly be possible to choose a model without gas (MOG) or with gas/without gas (MIG/MAG).
The catalogue also includes multiprocess MIG/MAG welders.
Here is a summary of the main features to take into consideration for choosing a wire welding machine:
