Helmets are universally acknowledged as an essential protective device in the welding industry as no welding operations shouls be done without a special protection for the eyes. Auto darkening welding helmet is the modern day innovation and hotly favored by many welding operators.

It is common knowledge that several types of light radiate from the welding arc including ultraviolet (UV), high-intensity light and infrared (IR). These rays are highly pernicious and can lead to severe and at times permanent damage to the eyes.

The basic feature of auto darkening welding helmets is they change color the moment the electric arc is stuck. But you must make it a point to buy the auto darkening helmets only from some reputed manufacturers and ensure the helmets conform to ANSI standard Z87.1 on the auto-darkening cartridge. When you find a reasonably priced auto darkening welding helmet with excellent user reviews that has these specs, you can buy with confidence.

There may be fakes in the market and this is the best certification possible to satisfy your eyes are protected. Some better model auto darkening welding helmets provide a higher level of comfort than others and this depend on the speed of darkening response to the light emission. Sometimes even a millisecond in the time of darkening can make a difference.

There are two types of power used in the auto darkening welding helmets - solar-powered and battery power. The advantage of the solar-powered auto darkening welding helmets is that they provide UV and IR protection even when the eye shield has not changed color. They function automatically and protect the eyes against high-intensity light instantly. The battery-powered model has an on-off switch as well as an auto-off device as these are necessary for prolonging battery life.

The auto darkening welding helmets have fixed or variable shades depending on the model. The fixed type of shade is useful to welders who operate on the same type of material. But it is recommended that you opt for the auto darkening welding helmets with a variable shade option.

When the welding process uses lower amperages, you may lighten the shades and when the amperage is too high you can darken the lens. Wearing an auto darkening helmet will provide you comfort and confidence and make you a more efficient welding operator.

Auto darkening welding helmets offer a guaranteed protection to present day welding operators. These helmets automatically darken when an operator strikes the arc. Besides, they free the hands that in the past were busy adjusting the faceplate, or removing the helmet altogether to see.

Auto darkening helmets fully cover a welder’s eyes at all times without risking exposure to irritating fumes and flying debris. By instantly responding to light, these helmets auto darken when the welder strikes the arc and stops when the welder shuts off the arc. High end auto darkening helmets have a sensor built into their design that understands the difference between the operator’s arc and a coworker’s arc. For industries, it is best to invest in high-end auto darkening welding helmets to have a sensor for secondary arc light.

The process by which two materials like steel, aluminum, brass, and stainless steel are joined by fusing them is called welding and the welder is the equipment used for the process of welding. During the process the molten metal called filler is made used to keep the pieces that are to be attached as one. There are different types of energy sources that are and that can be made use of for welding matters. For example, powerful energy sources like gas flame, an electric arc, a laser, an electron beam, friction and ultra sound is used for the process of welding. There are different types of welding and they are mainly differentiated with the process by which they work. Arc welding, MIG welding, TIG welding, Stick welding are the types of welding that is in usage.

Mig Welding: Metal Inert Gas welding is known to be Mig Welding. This is also known to be Gas Metal Arc Welding or else GMAW. This is made use for fusing the metal aluminum with any other non-ferrous metal. It is used to join a many kinds of alloys and metals and we can only find a very little splatter in this kind of welding process. An unremitting, delicate wire electrode and shielding gas are supplied with a welding gun. The equipments necessary for this kind of welding is a welding gun, a wire feed unit, a shielding gas supply and an electrode wire. A steady and continuous source of power is required for welding a steel or aluminum. This kind of weld method is for the most part followed in the sheet metal manufacturing and is as a result a great deal used in the automobile manufacturing industries. . This technique is comparatively more rapid that other time honored techniques like the stick welding system.

Shield Metal Arc Welding is also being called and known as Manual Metal Arc in the trade. This method of welding is mainly used for welding steel stainless steel and cast iron materials. Things like a consumable electrode coated in flux are made use of to lay the weld in this Shield Metal Arc Welding. The equipments necessary for this kind of welding is a continuous power supply, an electrode, an electrode holder and a work clamp to hold.

TIG welding is nothing but Tungsten Inert Gas welding and this kind of welding is done manually. Magnesium and aluminum are the reactive metals that are joined with the process of TIG welding. An inert gas is used for this method as the source of energy. This type of welding is mostly used to join thin metals like aluminum, magnesium alloys, steel, stainless steel, copper, brass and titanium.

When compared with other welding processes Arc welding needs only low-cost tools and electric current as it’s energy source, which is easily acquired everywhere without trouble. One of the contemporary systems is a laser beam welding or energy beam welding.

MIG welding, as most of us are aware, is a semi-automatic arc welding process in which a continuous, consumable wire electrode and a shielding gas are fed through a welding gun. At the end of the gun, there is a contact tip which passes electricity to the wire. Both the wire and shielding gas are activated to create the weld when the operator depresses the trigger of the gun.
Pros of MIG welding
This welding is quite popular as it is easy to learn and calls for no special skills. Even a first-time operator will be able to achieve a good weld with minimum practice.
People favor MIG welding as it is a much faster than Stick welding and saves time. Thus operating cost of this welding is lower than Stick welding because of this saving of time. MIG adjusts to limited electrode length and this allows for longer welds with fewer interruptions.
Besides, there is also no waste of filler metals and generally speaking, thinner materials can be welded far more easily with MIG than Stick welding. One more reason people favor MIG welding is because MIG welding is a tidy process and does not require chipping slag as in Stick welding. MIG certainly makes for very convenient weld tacking and fitting of parts and there is very scant stub loss due to the continuous spool of filler metal.
This welding is versatile and capable for a variety of applications, including - trailer hitches, auto body repair and restoration, farm/ranch equipment, household projects, repairing wheel barrows, bicycles, etc. This type of welding demands less time when compared to other types of welding processes.
Cons of MIG welding
The initial cost of MIG set up is high in view of the regulators and shielding gas - though some MIG welding may be done with self-shielding flux core and without gas or a regulator.
It is indeed a fact that all types of material can be welded with a MIG machine. But, in the MIG process different materials require different wire and gases. For instance mild steel can be welded with either self-shielded wire or with CO2 or a CO2 mixed gas but aluminum material requires the use of Argon gas.
It is inadvisable to weld through dirty materials with MIG machines.

It is said one should always weld on the cleanest possible material, so for best results scrape off paint, rust or other debris where the weld is being made.
There is no denying that MIG welding equipment is more complex, expensive and less portable and the welding gun is difficult to maneuver. Filler metal can become tangled within the wire feeder making the operator feel annoyed and also adding to downtime. The operator has to patiently keep leads and liners in straight position to allow for proper feeding of filler metal.
Summing up

When electrically charged wire is fed into the welding arc then it is MIG welding. MIG is commonly preferred because the welding leads are very easy to perform. As a matter of fact, it is said that even robots can be utilized to get the mechanical job done. MIG welder is capable of working with almost all kids of metals, though aluminum and mild steel are the most popular ones.

Tungsten Inert Gas (TIG) welder works by a process that uses a tungsten electrode to produce a weld and hence the name. A TIG welder creates an arc between the metal to be joined and the tungsten electrode. The arc creates the weld and protected from the elements by gas being fed to the arc. A TIG weld produces enormous heat and electricity, and the welder must compulsively wear a safety shield particularly to protect the eyes.
Metal Inert Gas (MIG) welding uses a wire, which dissolves upon the completion of the weld. But TIG welding uses tungsten electrodes that do not burn off or dissolve during the welding process. TIG welding is used with thin layers of stainless steel, aluminum, copper and magnesium alloys.
TIG welding is quite a complex process and demands the use of both the hands during the welding process. The welder must maintain a short arc in order for the weld to be effective.
The ultraviolet light created by the arc could be harmful and the operator must wear protective clothing and gloves, to cover exposed skin. TIG welding, if done unguardedly, can seriously affect your vision and TIG can also burn your hands. You must use thick leather welding gloves, and a welding helmet, and closed-toe shoes. To avoid sunburn, wear a long-sleeved shirt, or still preferably a welding coat. But the rewards of TIG welding are high as TIG weld produces high quality, clean welds.
While doing TIG welding you must be careful not to touch the metal with the electrode. Any contact might as well produce a crater and weaken the weld point. When the arc is struck, a welder will move the metal in a circular motion as it is fed forward, in order to produce the weld. A true blessing for the operator is TIG welds can be made in all positions - flat, horizontal, vertical or even overhead.
Another redeeming feature is TIG welding does not create smoke or fumes, except in rare cases where the base metal being welded contains contaminants such as, oil, grease, paint, lead or zinc. The base metal should be therefore be thoroughly cleaned before TIG welding. Because only the necessary amount of filler metal is added to the welding puddle, TIG weld does not cause spatter or produce any spark.

The operator needs tremendous practice to gain proficiency in TIG welding. Many beginners generally practice TIG welding on waste scrap or discarded pieces to develop mastery.
TIG welders can be used to weld steel, stainless steel, aluminum, nickel alloys, magnesium, copper, brass, bronze, and even gold. TIG welding has many applications and widely used for welding wagons, bike frames, lawn mowers, door handles, fenders, and a host of other items. For doing TIG welding on aluminum, it is recommended to use pure argon. For steel, you can use an argon/carbon dioxide mixture. The gas that is used is important to keep the weld from becoming corroded, as metal will rust.
No TIG welding process is deemed complete till the welder is properly shut down. The prescribed cleaning methods should be followed to remove any particulates that might have accumulated during the welding process.
