Precaution MIG Welders:

Friday, February 25th, 2011

MIG welding stands for Metal Inert Gas Welding. It is the most common form of industrial welding. It is also known as MAG welding which stands for Metal Active Gas Welding and Gas Metal Arc Welding (GMAW welding). When it comes to welding or joining of two or more pieces of metals, MIG welding is preferred and used. However it can be quite hazardous. Yes, it is one among the easiest welding processes to learn. However it requires serious expertise, proper training, and hard work to overcome the diverse range of industrial hurdles whose hazardous factor varies in degrees.

Most hazards are caused due to fire. Thus it is the serious cause of danger associated with MIG Welding. The light and sparks can cause damage to the eyes. In some scenarios, the damage is even permanent as the worker is even capable of losing his eye sight. So, we should always be aware and precautious when it comes to welding. We should wear protective clothes that don’t expose our bodily parts to these sparks created during the welding process. See to that you wear welding helmet before you start the process. This is mainly for protecting your eye sight from lights and sparks caused by the welding tool. Wear proper veils to protect yourself from breathing the harmful gas generated while performing the welding. The workshop should have proper ventilation and see to that, that there is always a fire extinguisher and a bucket of sand nearby while performing the task. These precautionary accessories are quite cheap as well.

The Safest Ways to do MIG welding:

Monday, February 14th, 2011

Metal inert gas welding or MIG welding as it’s more popularly known is one of the welding methods which are versatile, time saving and easy to learn. Welding is a process which must be done keeping a lot of safety tips in mind.

MIG welding is a process where one uses a welding gun whose tip supplies electrical energy to the wire. This welding generates a lot of heat and fumes. So in order to be safe one must make sure he is protected from the heat and harmful UV rays by having glasses and mask. If one is going to do MIG welding for a long period of time then he can consider having an auto darkening mask which fits the face, so the welder can use both his hands without feeling the burden of holding the mask. Also taking safety precautions by ensuring that there are no flammable materials, wearing cotton or full sleeved clothing, boots etc will be of help. Another important safety tip will be that you have a fire extinguisher along with you that will help you in case of any untoward incidents.

Safety Tips for Mig Mag Welding

Monday, February 7th, 2011

Even though the Welding industry is getting updated with more and more new products in the market there is still a craze for the older proven welders and one of the welding methods being used for a long time now are the MIG MAG welding technique. MIG stands for metal inert gas and MAG stands for metal active gas.

Mig Mag welders are actually two welders combined into one, it’s one of the easiest welding methods and they do not even require safety equipments like shielding gas. The quality of the weld depends upon a number of factors ranging from the wind. The Mig Mag welders can be used in welding without the person having a shielding glass but in general welding is a dangerous process and has to be dealt with caution.

So it’s necessary that the welder has a protective gear like a jacket which will not keep his body exposed and gloves that protect his hands. The eyes are the most sensitive part of the human body so it’s necessary that one wears glasses to protect the retina, also ensure that while you weld no one is exposed to the UV rays by having a screen.

MIG Welding – Don’t take it too lightly!!

Friday, February 4th, 2011

Metal inert gas (MIG) welding is the most common form of industrial welding. It is also called as metal active gas (MAG) welding and gas metal arc welding (GMAW). It is the common method of welding used universally, however it’s the most dangerous method as well. Even though MIG Welding is the easiest process to learn, it requires thorough training for handling the wide range of industrial situations.

The major danger associated with the MIG welding is the fire. The light and the sparks will cause permanent damage to the eyes. So it’s better to wear protective clothing and have the safety gear on. Even the fragments of metal are highly dangerous, so make sure the workshop has good ventilation facilities and it’s preferable to wear a mask. Instead of a fire extinguisher you can even use a bucket of sand to saturate flames, which is as effective as an extinguisher and it’s cheaper.

MIG welding can be taken as a career as MIG welders are in good demand and can have a high income career. There are specific an advance level training given in the MIG schools. These two trainings help the MIG welders to learn and earn.

Factors to consider while choosing MIG welder:

Thursday, November 4th, 2010

• MIG welders come in 115-volt or 230-volt models. A 115 volt welder works well for thinner metals; 230 volt models can accommodate metals up to 1 1/2 inches thick. Decide what voltage you require.

• Decide on the length of duty cycle you require. For instance, duty cycle indicates how many minutes a welder can operate in a 10 minutes period without overheating.

• Find out if you need to weld using multiple wire thicknesses. For example, some MIG welders work better for small jobs using 0.03 inch wire.

• Decide what types of metal you will weld.

• Decide if you want to shield with pure carbon dioxide or if you want to shield with an argon and carbon dioxide mix. The compressed gas protects the pool of heated metal from elements in the air. For instance, normal air contains hydrogen, nitrogen and oxygen.

• Compare features. Many features include overload protection, short-circuit protection and a contactor.

• Make sure MIG welder fits your budget.

• Compare warranties. Your MIG welder should come with a warranty that ranges from two to three years.

Little more to know about MIG welding:

Friday, October 29th, 2010

An arc fusing method that joins metals by using heat with an arc called MIG welding. There are a number of welders that can virtually meet all fusing requirements that start from industrial MIG welders to manufacture stores, farms, aerospace and more.

In this type of welding one can also utilize an inert gas to defend flux core and in that way it doubles the security. It is always suggested to buy a double function instrument that can do MIG as well as Flux core. As it is modifiable you can change the size according to the intensity of substance you plan to fuse.

In fact, most of the people think MIG gun consumables to be a product but they are gears that play a vital role by doing quality welding. They can make a great impact on the entire production as well as expenditure of the total function. Therefore, it is essential to get the greatest potential and quality consumables for the business operations. The type of power source which you utilize definitely manipulates the quality, so try to use good power source to get good result.

Things to look into when you buy an expensive MIG welder

Tuesday, August 31st, 2010

If you notice quality of MIG welders have come down as most of them are manufactured in Eastern Europe and China. If you buy cheap MIG welders you have to compromise on functionality. The major advantage of buying a slightly more expensive welder is that wire feed control automatically varies according to power. Wire speed knob does not require fiddling when you change power settings. If you buy one of these you will never regret. In addition, if you buy a slightly expensive welder you can get a good sized feed motor and a quality wire feed mechanism. If you buy an expensive MIG welder which will cost somewhere around £200 to £500 you can avail more benefits in the long run. Generally expensive welders have two controls –one for power and the other for wire speed. Another control is spot timer.

MIG WELDING – An overview:

Friday, August 20th, 2010

MIG welding was originally developed in 1940 for welding aluminum and other metals. Main advantage of this welding is metal can be welded much faster than traditional welding techniques. It can weld softer metals like aluminum. When MIG welding was first developed, cost of inert gas made the process too expensive for welding steel. In addition, it also produces long continuous welds much faster than traditional welding methods. MIG welding produces a clean weld with very little splatter. MIG welding can be used with a wide variety of metals and alloys. This type of welding is commonly used in the automobile industry because of its ability to produce clean welds and it can weld metals quickly. People favor MIG welding as it is much faster and saves time. The operating cost is lower and it can adjust to limited electrode length and this allows for longer welds with fewer interruptions.
