What is a welding machine?
Also known under the term of welding station, this name, in fact, gives off a certain clarity which is actually a definition of the device. The verb “to weld” is synonymous with assembling, joining, etc. A machine used for welding is a device which is at the origin of the joining certain elements. Especially for this case, it is the join of metals.
The welding machine is, therefore, an electrical device enabling two parts to be joined so that on the atomic level the two materials involved in the process become one. Technically, it can be defined as a transformer modifying the input current into electrical welding current. It all depends on what use we reserve for the final product or what we need.
Depending on the type of welding you are dealing with, the machine can be plugged into an electrical outlet or connected to a gas cylinder. It is for this reason that this type of device is generally portable so that it can be easily moved on construction sites for major works. On the other hand, for certain large industrial-type works are used industrial welding machines designed for on-site use.
As far as the use of mains or electric current is concerned, we find ourselves casually in the case of arc welding. Otherwise, the use of a source other than the mains current like gas cylinders involves a flame for the welding operation.
In its operating process, a certain level of temperature is necessary so that the material concerned can undergo modifications.
Generally used in industry, but also in our homes for current needs, the welding machine is an essential device in the joining different metals. Depending on the welding method and the type of metal used, a minimum level of temperature is required for melting.
Types of inverter welding machines
There are basically 3 types of inverter welders: MMA, MIG-MAG and TIG. The MMA inverter welder uses so-called electrode welding and is one of the most popular on the market, in fact, it is the most suitable for beginners. The model creates an electric arc between a consumable electrode placed on the clamp and the parts to be welded. This welding system, in addition to being the simplest and cheapest, since it only requires electrodes and electricity, is also the most effective for welding dirty or rusty metal parts.
The MIG-MAG welder is used for continuous wire welding and its operation does not require the presence of the electrode. The electric arc is between the workpiece and a metal wire which is automatically driven by the machine at a predefined speed. The TIG inverter welding machine is based on gas and electrode welding with a non-consumable tungsten electrode. In order to protect the area to be welded from any contamination, a special gas, generally argon, supported by a filler metal, is used to weld stainless steel, special iron alloys and alloys of non-ferrous materials such as than copper, aluminium and magnesium.
Why do I have to wear a welding mask?
To protect yourself from the light you need to wear a welding mask. The principle of arc welding is based on the creation of an electric arc between a metal rod and the part to be welded. The arc welding generates a temperature from 3,000 to 20,000 °C which melts the metal. It also emits intense blue light as well as ultraviolet. Blue light is very energetic and causes serious damage to the lens and retina of the eyes.
Safe from ultraviolet
As for ultraviolet light, it can generate inflammation of the cornea, conjunctivitis, cataracts and even eye cancer. Of course, these ultraviolet rays also attack the skin, hence the covering mask and the need to wear gloves.
